At a Glance: 2026 Outback, Forester and Crosstrek

Symmetrical AWD vs 4WD: Why There's No Low Range

Subaru explains the difference itself. Full-time AWD, which most Subarus use, sends some power to both axles at all times and varies the split as sensors detect slip. A 4WD system typically offers two ranges the driver shifts between: high range for normal driving and low range for particularly difficult terrain. Subaru's substitute for a low range is X-MODE, which the company says optimizes engine output and CVT ratio and adds hill descent control. On the Wilderness trims, dual-function X-MODE adds Snow/Dirt and Deep Snow/Mud settings, and Low Speed / Low Ratio Gradient Control can detect a steep climb and shift the CVT to its lowest ratio.

The Wilderness models also get shorter gearing. Subaru's 2024 Crosstrek Wilderness release lists a 4.111 final drive against 3.700 on other Crosstreks; the 2026 Forester spec sheet lists the same 4.111 against 3.700; and the 2025 Outback spec sheet lists 4.444 on the Wilderness, 4.111 on the XT and 3.900 on the 2.5-liter. A shorter final drive multiplies torque at the wheels, which helps at crawling speed, but it is not a substitute for a two-speed transfer case. That drivetrain, not any accessory, sets the ceiling on how technical a trail any of these cars should attempt; our are Subarus good off-road guide covers where that line falls.

Ground Clearance and Trail Angles by Trim

Subaru gets the Wilderness height from longer springs and shocks rather than bolt-on spacers; its Crosstrek Wilderness release credits longer coil springs and shock absorbers for the added clearance and longer strokes for keeping the tires on rough ground. Every Wilderness also adds underbody protection, and the Crosstrek Wilderness release specifically lists a metal front skid plate. The Outback's long rear overhang shows in its departure angle, which is the lowest of the three even in Wilderness form.

Roof Load Ratings: The Ceiling for Rooftop Tents

Subaru publishes both numbers for its current off-road-oriented rails. The 2026 Outback's standard raised rails, and the Outback Wilderness's ladder-type rails, carry 220 lb dynamic and 800 lb static. The 2026 Forester Wilderness's rails carry 176 lb dynamic and 800 lb static. The Crosstrek Wilderness's ladder-type rails carry 165 lb dynamic and 700 lb static, which Subaru says allows use of larger rooftop tents. The dynamic number is the one that limits the drive: a tent and its crossbars together must fit under it. For a worked example with a 165-lb tent, see roof racks and rooftop tents; for older generations, check the owner's manual for your model year rather than assuming current figures apply.

Factory Tire Sizes and Realistic Upsizes

Tire diameter is the rim size plus twice the sidewall height, and the sidewall is the width times the aspect ratio: 225 mm × 0.65 ≈ 146 mm, or 5.76 inches, so a 225/65R17 is about 17 + 11.5 = 28.5 inches tall. The upsizes in RalliTEK's chart are about an inch over stock. The company also lists "aggressive" sizes — for example 245/70R17 (30.5 inches) on the Outback and 235/70R17 (30 inches) on the 2024-and-later Crosstrek — for 2–3 inch lifts, and says those can require trimming plastic, flattening the pinch weld or heating the inner fender liner out of the way. More on sizing in all-terrain and mud tires.

Lift Options: Spring Kits, Not Just Spacers

Aftermarket lifts for these unibody cars are smaller than truck lifts, but they are not limited to strut spacers. RalliTEK's 2-inch kit for the 2024–2026 Crosstrek Wilderness, for example, raises the car 2 inches over the factory Wilderness height using replacement springs rated 190 in-lb in front and 260 in-lb in back, which the company says is 20% and 30% stiffer than stock. Because lifting a Subaru changes rear alignment, it sells two correction options: rear subframe drops, which it calls the cheapest route to factory alignment specs, and adjustable rear arms, which restore alignment without giving up clearance at the rear differential. The same company lists a 3-inch kit for the 2026 Outback Wilderness. As with any lift, plan on an alignment afterward and read the suspension and lift kits hub for how spring rate and geometry affect ride.

Towing Ratings

Subaru's 2026 spec pages list 1,500 lb for standard Crosstrek and Forester models, 2,700 lb for the 2.5-liter Outback Premium, Limited and Touring, and 3,500 lb for the Outback Limited XT, Touring XT and all three Wilderness models. The Forester Wilderness reaches its figure with an uprated transmission cooler, according to Subaru. The 2025 Outback spec sheet pairs its ratings with tongue weights of 270 lb (2,700-lb rating) and 350 lb (3,500-lb rating). Subaru sells the Outback Wilderness hitch as an accessory with a combined 7-pin and 4-pin connector; check tongue weight against the hitch rating as well as the vehicle rating.

How to Choose Subaru Accessories

Confirm your exact model year and trim first: roof ratings, final drive, tire size and towing all change between standard and Wilderness versions. Check the dynamic roof rating before buying a rooftop tent, the lift maker's listed tire sizes before buying tires, and the tow rating before buying a trailer. Every fitment note on this hub comes from Subaru's published specifications and makers' compatibility charts, backed by owner fitment reports; we don't buy, install or test this gear ourselves — see how we rank.
