Subaru Outback Towing Package: Real Limits, Smart Setups & Costly Mistakes

Bikes, kayaks, maybe a small camper, the Outback’s 3,500-pound tow rating makes it sound ready for all of it. But unlike full-size trucks, there’s no factory-installed heavy-duty radiator, auxiliary cooler, or stiffer suspension.

Here’s the reality: most Outbacks ship with nothing. No hitch. No wiring. No brake controller. Subaru’s so-called “towing package” is just an accessory bundle, hardware tacked on at the dealer or added later in the garage.

That leaves drivers guessing about hitch classes, wiring setups, and how close they can run to that 2,700- or 3,500-lb limit without cooking the CVT.

This guide breaks it down. Exact ratings by engine and trim. Factory vs. aftermarket hitches. Which wiring and brake controllers actually work.

And how to load smart without blowing your payload margin. Whether it’s a lawn trailer or a teardrop camper, this is how to tow without regret.

2022 Subaru Outback Wilderness

1. What Subaru’s “towing package” really means

No heavy-duty cooling hiding under the hood

Don’t expect the kind of tow package you’d get from Ford or Chevy. Those add bigger radiators, stronger alternators, and separate transmission coolers. Subaru skips all that.

The Outback keeps its stock radiator, CVT, and suspension across the board. The only difference is what’s bolted on: a hitch, wiring, and maybe a ball mount. That’s the whole “package.”

Only the Wilderness trim comes with a hitch from the factory. Everywhere else, it’s a dealer add-on. So when the spec sheet says “towing package,” think accessory kit, not drivetrain upgrade. And that matters when you’re asking a CVT to pull a 3,000-lb trailer through the mountains.

The bare minimum to tow safely

To tow anything safely and legally, you need three basics:

1. Receiver hitch. Either Subaru’s OEM part (L101SAN000) or a solid Class III aftermarket hitch with a 2-inch receiver. Class II hitches with a 1¼-inch opening exist but limit accessories and future upgrades.

2. Wiring harness. A 4-pin handles lights only. Go 7-pin if you’re adding trailer brakes or a charge line. Subaru offers both, and aftermarket kits with powered modules work just as well.

3. Ball mount and hitch ball. Match them to your trailer’s coupler and height. Aim for a level stance; nose-up or tail-dragging ruins stability.

Skip one of these, and you’re either illegal (no lights), overloaded, or stressing tires and suspension with poor trailer geometry.

Add-ons that make towing less stressful

The right extras make a big difference. A proportional brake controller, like the REDARC Tow-Pro Liberty or Tekonsha Primus IQ, syncs trailer braking with your foot. Extended mirrors help you keep track of what’s behind.

If tongue weight pushes the limit (270 lb for the 2.5L, 350 lb for the 2.4T), rear spring upgrades or airbags help keep things level. And for peace of mind, an OBD-II dongle that shows CVT temps gives you more real-world protection than any warranty promise.

2. Ratings that matter, not rumors

The engine sets your limit, not the trim badge

Subaru rates Outbacks by engine, not by features or trim names. The naturally aspirated 2.5L caps out at 2,700 lb of tow rating and 270 lb tongue weight.

Step up to the 2.4L turbo, and you get 3,500 lb with a 350 lb tongue. The Wilderness trim uses the turbo setup. If you’re shopping used, the old 3.6R splits the difference.

Outback towing capacity by engine

Model Years Engine Max Tow (lb) Max Tongue (lb) Typical Trims
2020–2025 2.5L NA BOXER 2,700 270 Base, Premium, Onyx, Limited, Touring
2020–2025 2.4L Turbo BOXER 3,500 350 Onyx XT, Limited XT, Touring XT, Wilderness
2015–2019 2.5i 2,700 270 All 2.5i
2015–2019 3.6R H6 3,000 300 3.6R
2010–2014 2.5i 2,700 270 2.5i
2010–2014 3.6R H6 3,000 300 3.6R

Torque is what gives the turbo its edge. The 2.4T puts down 277 lb-ft from just under 2,000 rpm to almost 5,000. That low-end grunt means cleaner launches and steadier climbs, without leaning so hard on the CVT.

If your trailer lives near 3,000 lb, go turbo. For smaller trailers under 2,000 lb, the 2.5L works well if you keep wind and hills in check.

Payload is the wall you’ll hit first

Tow ratings grab headlines, but payload is what limits real-world setups. It’s on your door jamb sticker, and tongue weight eats into it fast.

Plan for tongue weight to run 10–15% of your trailer’s total. Then subtract every person, bike, cooler, or dog riding in the car. Most Outbacks carry 950–1,150 lb of payload, so it adds up fast.

Sample payload math

Item Weight (lb)
Payload sticker 1,050
Driver + 2 passengers −460
Roof gear, bikes −80
Cargo in rear −120
Payload left for tongue 390
Safe trailer est. @ 12% 2,600–3,200

Boxy trailers drag harder than they weigh

Towing isn’t just about pounds; it’s about air. A tall, blunt camper under 2,700 lb can strain the 2.5L more than a sleeker, heavier trailer. Big frontal area acts like a parachute, especially in headwinds or on long climbs.

The CVT will hold higher rpm to keep speed, raising heat. Don’t fight it. Ease up on cruise speeds and let the car idle a bit before shutting off after a long haul.

3. Hitch and wiring choices that make or break the setup

Receiver size locks in your options

The Outback accepts both 1¼-inch and 2-inch receivers, but that choice shapes everything that follows. Subaru’s older 1¼-inch Class II hitches fit tight to the bumper but limit what you can tow, or even carry.

Most bike racks, cargo trays, and weight-distribution hitches are built for 2-inch. That makes a Class III 2-inch setup the smart long-term play.

Mounting style matters too. Concealed hitches hide the cross-tube behind the bumper, leaving only the receiver visible. Cleaner look, better clearance.

Exposed hitches hang lower and install easier, but they’ll scrape on driveways or trailheads. Subaru’s OEM hitch even replaces the rear bumper beam to keep crash-energy paths intact, added safety, added cost.

Wiring that makes you street legal

Trailer lights aren’t optional. A flat 4-pin covers the basics, brakes, blinkers, and markers. That’s fine for a 1,000-lb utility trailer. But once you need electric brakes, reverse lights, or a charge line, a round 7-pin becomes mandatory. And you’ll need a controller in the cabin.

Aftermarket harnesses use powered converters to protect the Outback’s CAN-bus from current spikes. Subaru’s harnesses do the same, but you’ll pay more for the logo. Either way, sloppy splices and bad grounds cause headaches, flashing faults, dim lights, or trailers that never register.

Brand breakdown: what’s worth your money

Subaru’s L101SAN000 hitch integrates cleanly and preserves crash structure, but the install means removing the bumper. Curt offers exposed and concealed bolt-on setups at lower prices.

Stealth hitches disappear completely and include a removable mount, great for looks and theft protection, but pricey. Draw-Tite leans on thick chain loops and a J-pin to silence rattle.

Hitch and wiring options

Brand / Option Style Class / Receiver Key Pros Trade-Offs
Subaru OEM (L101SAN000) Concealed, replaces beam Class III / 2″ Factory fit, crash-tested Higher cost, bumper removal
Curt Concealed or exposed Class III / 2″ Widely available, coated, bolt-on Exposed versions reduce clearance
Stealth Fully hidden, removable Class III / 2″ Cleanest look, anti-theft pin Highest price, proprietary parts
Draw-Tite Concealed or exposed Class III / 2″ Heavy-duty loops, J-pin for rattle Some models show cross-tube
Wiring (4-pin) Flat 4 N/A Simple, light-only use No brakes, no charge line
Wiring (7-pin) Round 7 N/A Full brake/charge/reverse setup More install effort, needs controller

Just remember, no hitch upgrade can override the Outback’s factory limits. The drivetrain, cooling, and payload rating still call the shots.

4. Brakes that stop the fight, not start it

When trailer brakes become mandatory

Most states require brakes once the trailer’s GVWR hits 1,500 to 3,000 lb. Cross that line, and brakes aren’t optional. Even under that weight, they’re smart insurance, especially with hills, heat, and loaded coolers.

Trailer brakes cut stopping distance, prevent fade, and keep the camper from shoving the Outback when traffic stops hard.

To run them, you’ll need a 7-pin plug, a working breakaway battery, and a controller inside the vehicle.

Choose a controller that behaves like your foot

Skip the time-delay stuff. Go proportional. It matches trailer braking to how hard you’re pressing the pedal, smooth, straight stops with no surprises. Time-delay models apply a preset curve, which can grab early or push late, especially on dirt or wet roads.

For Outbacks, REDARC’s Tow-Pro Liberty is clean and low-profile. The control knob mounts on a blank dash panel, and the brain hides under the dash.

Tekonsha’s Primus IQ is more visible but gives you a clear LED readout and easy gain control. CURT’s Echo plugs into the 7-pin and links to your phone, no drilling, great for rotating between vehicles.

Trailer brake controller options

Model Type Install Style Best For Watch Outs
REDARC Tow-Pro Liberty Proportional Hidden brain, dash knob Clean OEM-style installs Drill carefully, avoid knee airbag zone
Tekonsha Primus IQ Proportional Visible under dash Budget builds, easy tuning Needs solid bracket and line of sight
CURT Echo Mobile Proportional Plug-in at 7-pin Multiple tow vehicles, renters Phone battery drain, keep Bluetooth solid

Wiring it wrong? Get ready for ghost faults

A 7-pin setup needs more than lights. You’ll need a fused 12V charge line to the trailer battery, a blue brake output wire from the controller, and a solid chassis ground.

Use a powered converter to keep the CAN-bus safe. Run fused lines from the Outback’s battery, and anchor every span. Loose grounds and corroded pins trigger most “trailer not detected” messages.

Troubles you’ll spot first

If stops feel choppy, it’s likely a time-delay controller or a load shifting too far forward. “Trailer not connected” almost always points to corrosion or a weak ground.

If the lights flicker or pulse, it’s probably LED fixtures without a proper load resistor. If the controller lights up but doesn’t apply brakes, start hunting for a blown 12V fuse. Always fix wiring before blaming the car.

5. Powertrain heat management that decides your day

Why the turbo stays cooler under pressure

The 2.4T makes 277 lb-ft from 2,000 to 4,800 rpm, torque right where you need it. It pulls a 3,000-lb trailer without revving to the moon or crushing the CVT at high load.

The 2.5L can do the job, but needs more throttle and rpm to hold speed on hills or in wind. More strain equals more heat. That’s why the turbo feels calmer with the same load.

CVT heat builds quietly and quickly

Towing loads up the CVT, and heat follows. Subaru calls it “severe duty” for a reason. Think of fluid like brake pads; it wears faster under pressure.

The usual change window sits around 30,000 to 60,000 miles. If you tow regularly, shorten that gap. And log it. Clean fluid protects the chain and keeps the pump from cavitating during long climbs.

Airflow is everything, don’t block it

Up-front cargo trays or bulky bike racks cut airflow where you need it most. Starve the condenser or radiator, and temps spike fast. Keep the grille clear. Make sure underbody panels are intact.

Clean out leaf buildup near the A/C condenser. On hot days, turn off auto stop-start, set the HVAC to a constant temp, and let the fan move air during stops.

Use what gears you’ve got

The CVT simulates stepped gears. Paddle shifters can hold lower ratios downhill, giving the engine a chance to help with braking. On climbs, avoid jabs at the throttle.

Pick a steady input the car can sustain. Stay in the torque band, don’t chase speed. Smooth input reduces heat and saves wear on belts and brakes.

Telemetry turns guesses into action

Plug in an OBD-II dongle that shows temps and load. On long climbs, watch coolant temp trends. If power starts fading or warnings pop, you’re already in thermal protection mode. Slow down. Cut the next grade short. Let the drivetrain cool before you shut off the engine.

6. Wilderness and XT: where the extra torque pays rent

Strong hardware, but still plays by Outback rules

The XT and Wilderness trims bring real advantages, but they don’t turn the Outback into a half-ton. You get more torque, better clearance, and a factory tow rating of 3,500 lb. But cooling, brakes, and payload still matter. These are tough wagons, not trucks.

What comes built in

Every XT and Wilderness packs the 2.4T turbo engine, a 3,500-lb tow rating, and a 350-lb tongue cap. Wilderness adds 9.5 inches of ground clearance, skid plates, and all-terrain tires.

A hitch usually comes pre-installed on Wilderness or gets added at delivery for XT trims. Symmetrical AWD and a low center of gravity keep things stable, but there’s no extra cooler under the hood.

Spec snapshot: XT and Wilderness

Trim Set Engine Max Tow (lb) Tongue (lb) Ground Clearance
XT Family 2.4T 3,500 350 8.7 in
Wilderness 2.4T 3,500 350 9.5 in

What still needs doing

You still need a proper Class III 2-inch hitch, a 7-pin socket, and a proportional brake controller. Wire it like a modern CAN-bus car deserves: use a powered converter, clean grounds, and a fused charge line.

If you’re running trailer brakes, mount the controller where you can adjust gain on the fly. Don’t expect stability control or driver aids to fix a poorly set-up rig.

Height, tires, and tongue angle matter more now

Wilderness rides taller, which means a standard ball mount often puts your trailer nose-up. Use a bigger drop to level the load, then double-check tongue weight.

All-terrain tires add rolling resistance and unsprung weight. Softer sidewalls, especially at highway pressure, can introduce sway. Choose a load rating that leaves headroom over your combined trailer and cargo weight.

Off-road terrain loads the system fast

Gravel, sand, and ruts feel like dragging extra weight. Starts take more throttle. Climbs run hotter. Brake distances grow longer. Derate your towing expectations off-pavement.

Drop your target trailer weight, drive slower, and cushion the tongue load. And with long-drop drawbars, mind the departure angle; even Wilderness bottoms out if the hitch is too low.

7. Loading and sway control that keep the wheel calm

Nail tongue weight or chase sway all day

Tongue weight should land between 10–15% of total trailer weight. For boxy campers, 12–13% is the sweet spot. Too light and the trailer wanders. Too heavy and you bury the rear suspension. Don’t eyeball it. Use a scale and get it right the first time.

Cargo placement that locks the trailer down

Keep 60% of the weight ahead of the axle. Load heavy gear low and forward, not high and behind the wheels. Strap everything tight so it doesn’t shift and wreck your balance mid-trip. A trailer that’s packed clean pulls straighter than one that’s slapped together.

Tires and speed make or break stability

Set tire pressures to spec, door sticker for the Outback, sidewall or trailer label for the camper. Soft tires flex and invite sway. Over-speeding does the same. Keep the cruise calm and knock it down in crosswinds or traffic.

Level the rig before you roll

The trailer should ride level, not nose-up or tail-heavy. Pick the right drop or rise for your ball mount so the coupler sits parallel to the ground. Even small angle shifts can swing tongue weight by 20–30 lb. After you level it, recheck the tongue number to stay inside your payload cap.

Simple sway control that pays off

A friction sway bar adds real stability for small to mid-size campers. Mount it on the 2-inch receiver, dial the knob with the trailer loaded, and listen. A bar that chatters quietly on tight turns is working. Total silence means it’s probably not doing anything.

Weight distribution on a unibody: real limits

You can use a weight distribution hitch if your Class III receiver is rated for it. Not all are, so check the label. Set the bars light. The goal isn’t to max out lift, it’s to shift just enough weight forward to settle the steering.

After setup, check your headlight aim and steering feel. If the front feels floaty, you’ve still got weight where it shouldn’t be.

Tongue weight: measure it like it matters

Load the trailer the way you’ll tow it. Park level, chock the wheels, and release the weight bars if they’re installed. Use a tongue scale under the jack or a Sherline gauge near the coupler.

Shift cargo forward or back to hit your target number, then lock it down. After a short drive, recheck it; some setups shift slightly under motion.

When sway starts, fix the inputs, not the car

If the trailer begins to wiggle, ease off the throttle and keep the wheel straight. If you’ve got trailer brakes, use them manually; don’t jab the car brakes.

Let the speed drop gradually, then pull over and check tongue weight, tire pressure, and load placement. Adding sway control or backing down your speed on the next leg usually solves it.

8. Driver aids with a trailer: what helps and what bites

What the cameras see with a trailer behind you

Subaru’s EyeSight system uses forward-facing stereo cameras, so the trailer won’t block them. But once you’re hitched up, the way the car reacts changes.

You’re carrying extra weight, which alters how it stops when EyeSight intervenes. Rearward visibility also takes a hit. Add mirror extensions or a trailer-mounted camera if you’re towing anything tall.

ACC and pre-collision are no safety net

Adaptive Cruise Control will do its best to maintain gap, but it can’t fight momentum. Trailers stretch braking distances and heat up rotors faster.

Use the longest gap setting, watch traffic like it’s a job, and start braking early. If ACC surges or stutters at low speed while towing, take over and drive it yourself.

Lane centering doesn’t know you’re towing

This feature assumes you’re driving a solo car, not one with a camper swaying behind. On crowned roads or in wind, those little steering nudges can start a wobble.

If the wheel feels twitchy while towing, shut lane centering off and keep a firm hand on the wheel. Trailers track straighter when you set the line.

Reverse aids and sensors need real-world testing

Backup cameras still work, but reverse auto braking and parking sensors can freak out when a drawbar or trailer tongue sits close to the bumper.

Subaru doesn’t publish trailer-specific EyeSight behavior, so test everything in a quiet lot before your first real trip. If a system false-triggers, disable it for the maneuver and turn it back on once you’re clear.

AWD and stability control polish, not prevent

Symmetrical AWD gives great traction on ramps and gravel. And Subaru’s Vehicle Dynamics Control system can trim throttle or brake a wheel to dampen a mild skid.

But neither will fix a bad load, light tongue weight, or poor trailer geometry. Load it right, air the tires properly, and keep speeds sane. The electronics are there to help, not to bail you out.

9. Costs and wrench time that decide your plan

What your wallet actually sees

It’s not just parts; you’ll pay for wiring, labor, and time under the car. The Class III 2-inch hitch anchors the setup. A 4-pin covers lights only. Go 7-pin if you want brakes and charge lines.

Controllers range from sleek and tucked away to plug-and-play types. The prices below reflect real-world market ranges, not cherry-picked deals.

Typical towing setup costs, Subaru Outback

Component DIY Parts ($) Pro Labor ($) Notes
Class III 2″ hitch 150–400 150–300 OEM higher, often requires bumper removal
4-pin wiring 50–150 80–200 Lights only
7-pin w/ charge line 120–250 150–300 Brakes, reverse circuit, 12V feed
Brake controller 100–250 80–200 REDARC and Primus IQ are solid picks
Ball mount and ball 30–100 Match rise/drop to level the trailer
Total Range 330–1,150 460–1,000 Mix varies by part choice and shop rates

What to expect in labor hours

Shops quote real hours, not ballpark guesses. Hitch installs take longer if the bumper beam has to come off or heat shields need trimming. Wiring time jumps when a charge line or reverse circuit enters the mix. These numbers hold if the car’s clean and rust-free.

Typical install hours (clean vehicle)

Task Pro Hours DIY Hours
Class III hitch, concealed 1.5–3 3–5
4-pin light harness 1–2 2–3
7-pin, charge line, reverse circuit 2–3.5 4–6
Brake controller and power 1–2 2–3
Ball mount leveling, road test 0.5–1 1–1.5

Where DIY saves you, and where it can bite back

Installing the hitch, 4-pin wiring, and ball mount is doable at home if you’re patient and follow torque specs. But 7-pin installs with a charge line demand clean crimps, proper fuse placement, and solid grounds.

Skip those, and you’ll spend weekends chasing ghost faults. Hard-mount controllers need smart placement too, never near a knee airbag or where your shin might slam into it.

How to make the install survive weather

Use a powered converter to protect the CAN-bus. Run the 12V line from the battery with a fuse within 12 inches, then loom and anchor every inch.

Seal the 7-pin bracket so water doesn’t corrode the contacts. Torque the hitch properly, check it after 100 miles, then recheck once per season.

Who should install what

If you’re handy, the hitch, ball mount, and basic 4-pin wiring are fair game. But leave the 7-pin, brake controller, and fused charge line to a pro, ideally a shop that does towing work weekly. Ask them to level the trailer under load and dial in the gain with you in the seat.

10. Pre-trip checks that actually prevent problems

The car setup that saves your trip

Start with the payload sticker, write it down. Cold-set the tire pressures per the door label, including the spare. Check fluid history; towing counts as severe duty, especially for CVT fluid.

Make sure brake pads aren’t low, pedal feel is smooth, and there’s no pull. Test all exterior lights and wipe the windshield clean where EyeSight watches the road. If you’re hauling roof gear, double-check that nothing blocks grille airflow.

The trailer prep that keeps it hooked

Torque the hitch hardware to spec and recheck it after 100 miles. Make sure the ball size matches the coupler, torque the nut, and insert the safety pin.

Level the trailer with the right drop or rise, then lock the coupler and secure the latch. Cross the safety chains under the tongue and hook them to frame-rated loops.

Don’t clip the breakaway cable to the same hook; it needs its own anchor. Plug in the 4- or 7-pin, test every light, and check that the trailer battery is charging if you’ve got one.

Load placement that stops sway before it starts

Keep tongue weight between 10–15%, closer to 12–13% for tall campers. Stack about 60% of cargo forward of the axle, keep heavy stuff low, and strap it tight. After loading, recheck tongue weight and payload math, trailers shift under real-world weight. Trailer tires should be set to the sidewall spec.

Inspect them for dry rot, bulges, or cracks. If you’re using a brake controller, set a conservative gain for your first run, then plan a safe spot to calibrate with the trailer fully loaded. Cruise speed should be modest. Add margin for hills and wind, and map fuel and cool-down stops ahead of time.

11. Use cases that match your trailer, not your hopes

Light-duty loads that just work

Keep total weight under 1,500 lb, and your 2.5L Outback handles it easily, yard trailers, small dirt bikes, flat cargo hauls. A Class III 2-inch hitch and a basic 4-pin harness cover the setup.

Aim for 10–12% tongue weight and don’t rush the cruise. Trailer brakes usually aren’t required at this weight, but check local laws; some states are stricter than others.

If sway shows up, it’s usually one of two things: your tongue’s too light or your trailer tires are too soft. Fix those before touching anything else.

Small campers that stretch the 2.5L

Between 1,500 and 2,700 lb, you’re towing at the edge of what the 2.5L can manage comfortably. This range demands a 7-pin harness, a solid proportional brake controller, and a tongue weight closer to 12–13%, especially for boxy campers.

Slower speeds help when wind kicks up. Use the paddles on grades to help the engine manage descent and heat. Treat CVT fluid like a wear item, change it often, log it, and protect your margin. Don’t eat up payload with gear that should have stayed in the trailer.

When the forecast calls for long climbs or strong headwinds, pack lighter. There’s no reserve left if you max everything out.

Big trailers that demand the turbo

Once you’re pushing past 2,700 lb, it’s time to put the 2.4T or Wilderness trims to work. Trailer brakes are non-negotiable. Use a 7-pin harness with a fused charge line and a controller you can adjust without taking your eyes off the road.

Match ball mount drop carefully to keep the trailer level, and confirm the tongue load stays below 350 lb. Add up your total payload with passengers and bikes; don’t guess.

If your camp gear tips you past the door sticker, you’re out of spec. That’s not just a warning, it’s the line between control and compromise.

12. Pitfalls and limits that catch Outback owners first

Cooling capacity you wish it had

Subaru doesn’t offer a heavy-duty radiator or supplemental transmission cooler. On long climbs, summer days, or windy highways, heat climbs fast.

There’s no hardware upgrade, only smarter driving. Margin, slower speeds, and early fluid service are your insurance policy. Ignore heat, and it becomes your tow limit whether you like it or not.

Payload, not tow rating, decides the trip

The tow rating may sell the car, but the payload sticker is what decides if the trip actually works. With a typical 1,050 lb rating, it doesn’t take much. Add two adults, a full cooler, and a 300-lb tongue weight, and you’re out of room. Run the math in your driveway before you’re stuck doing it at a rest stop.

Drag hurts more than weight

A 2,300-lb teardrop glides. A 2,300-lb box camper drags like a parachute. Frontal area hits the 2.5L hardest, forcing it to rev higher and burn more fuel just to hold speed.

Expect more noise, slower cruise, and heavier throttle input when the trailer stands tall. Route planning isn’t just about terrain; it’s about wind, too.

Stronger hitches don’t raise factory limits

The Class III 2-inch hitch is the right pick for strength and accessory fitment. But it doesn’t move Subaru’s factory tow ratings. You’re still capped at 2,700 or 3,500 lb, and the same tongue limits apply.

A stiffer drawbar might help reduce flex, but it won’t give you more margin. Hardware strength doesn’t override what the drivetrain and chassis are rated to handle.

WDH on a unibody: helpful but risky

Weight distribution can help smooth handling when you’re near max load, if the hitch is rated for it. Use light spring tension and measure front axle height before and after.

Don’t just crank the bars until it looks level. Too much tension stresses the rear structure and can make steering feel vague or twitchy. Always recheck headlight aim and test the setup on quiet roads before trusting it on a long haul.

EyeSight can’t read the trailer

The forward cameras still work fine, but the extra mass behind you changes how the car responds. Adaptive Cruise Control can misjudge gaps or brake harder than you expect.

Lane centering, which feels smooth when solo, might start a wag when towing a tall trailer. Test all driver aids hitched, then shut off the ones that create more work than help.

Towing makes CVT service mandatory, not optional

Subaru calls towing “severe duty” for a reason. The 30,000–60,000-mile service windows don’t apply if you tow even semi-regularly. Change the fluid early, log it, and save the invoice. Replacing it beats paying for a rebuild.

Cheap wiring causes expensive ghosts

Scotch-locks, exposed charge lines, and weak grounds are the fast lane to electrical headaches. Subaru’s CAN-bus needs a powered converter, properly fused feeds, and sealed connectors.

A corroded 7-pin or floating ground will trigger “trailer not connected” alerts at the worst moment. Do the wiring right once, and it goes quiet for good.

13. Buyer’s guide that matches your trailer, not the badge

Start with the trailer, then pick the engine

Don’t shop by trim. Write down your trailer’s real-world weight, loaded, packed, and ready to roll. If it stays under 2,000 lb, the 2.5L can do the job with the right setup. If it pushes 2,700 lb or more, you’ll want the 2.4T or Wilderness. Torque, not trim, decides whether the car works or sweats.

Near the max? Buy margin, not just power

XT and Wilderness trims give you a 3,500-lb tow rating and a 350-lb tongue cap. The 2.4T’s 277 lb-ft of torque makes launches smoother and grades easier.

Plan on a Class III 2-inch hitch, a 7-pin harness with a fused charge line, and a brake controller mounted where you can adjust it safely while driving. Keep your payload math tight, people, pets, and bikes still count.

Towing light? Save money smart

If your trailer stays under 2,000 lb and towing only happens a few weekends a year, the 2.5L is a strong value. Stick with a Class III 2-inch hitch and a 4-pin harness.

If you push past 1,500 lb or tackle hilly terrain, step up to a 7-pin and trailer brakes. Keep tongue weight around 10–12%, stay out of the fast lane, and the 2.5L will handle it without fuss.

Used models: where the sweet spots are

The 2015–2019 3.6R sits comfortably between the 2.5L and 2.4T. It tows up to 3,000 lb with a 300-lb tongue cap, and the flat-six delivers torque without the CVT squeeze.

Older 2.5i models still carry the 2,700-lb rating but often have less payload to work with. Watch for clean wiring installs, twisted splices, and sloppy controller mounts are red flags.

Upgrades that are worth real money

Look for a concealed hitch install, a prewired 7-pin, and a brake controller mounted cleanly, not zip-tied or crammed near your knee. If the trailer rides high, ask for a ball mount that matches drop or rise. Skip cosmetic extras and spend your budget on wiring and gear that won’t quit in the rain.

The Subaru Outback can tow confidently, but only if you respect its limits. It’s not a truck. There’s no heavy-duty cooling, no reinforced frame, no margin for guesswork. But when built right, it handles trailers with surprising composure.

If your load stays under 2,000 lb and you tow occasionally, the 2.5L handles it cleanly with proper hitching and wiring. But if you’re towing near 3,000 lb through hills or heat, the 2.4T or Wilderness trims earn their keep, because torque, not trim, buys peace of mind.

No matter the engine, everything comes down to the setup: nail payload math, keep tongue weight near 12%, wire it right, and add brakes when required.

Skip those, and the Outback feels maxed out before you leave your neighborhood. Do it right, and it tows calm, controlled, and efficient, just like it was built for the job.
