Stop Bottoming Out On Every Trail Without Sacrificing Daily Ride Quality
The 70-363791 lift kit from Bilstein swaps in four purpose-tuned B8 TerraSport dampers so your Outback gains real ground clearance, 2 inches up front and 1.4 inches in the rear, without the harsh ride or alignment headaches that come with cheap spacer lifts. Each damper uses a higher fixed spring perch and a longer body engineered specifically for this application, so your factory springs and top mounts bolt right back on and your factory alignment geometry stays intact.
Key Features
- Direct fit replacement using your factory springs and top mounts, no coil spring swap required
- Custom valving tuned specifically for the lifted ride height of 70-363791
- Monotube gas pressure design resists fade under sustained off-road use
- Higher fixed spring perch and longer damper body deliver a true 2 inch front and 1.4 inch rear lift
- Zinc-coated shock body and piston rod resist corrosion from mud, salt, and moisture
- Maintains factory-spec alignment angles at the new ride height
- Set of 4 dampers with all mounting hardware needed for installation

FAQ
What is the 70-363791?The 70-363791 is a Bilstein B8 TerraSport suspension lift kit for the 2015-2018 Subaru Outback that includes four custom-valved dampers to deliver a 2 inch front and 1.4 inch rear lift while reusing factory springs.
Does this kit include springs?No, this kit reuses your factory Outback springs and top mounts. Only the four dampers and mounting hardware are included.
Will this kit affect my factory alignment?No, the 70-363791 is engineered to maintain factory-spec alignment geometry at the new lifted ride height, so you should not need aftermarket alignment components.
What is the difference between B8 TerraSport and B8 5100?B8 TerraSport dampers are direct-fit units designed to work with your factory springs for a specific lift height, while the B8 5100 line is typically used with aftermarket coil springs or on truck platforms for a wider range of lift heights.
Can I install this kit at home?Yes, the 70-363791 bolts in place of your factory struts and shocks using standard hand tools, though a shop press may be needed to transfer springs and top mounts if they are not already assembled.
Does this kit fit all-wheel drive Outback models only?Yes, the 2015-2018 Outback was sold exclusively as an all-wheel drive vehicle in the US market, so this kit is compatible with all trims listed in the fitment table.
Is a spacer lift a good alternative to this kit?No, spacer lifts raise ride height without changing damper valving, which often results in a harsh ride and reduced damper travel. The 70-363791 uses purpose-tuned dampers instead of spacers for a more controlled ride.
What warranty does this kit carry?The Bilstein B8 TerraSport series carries a Limited Lifetime Warranty to the original purchaser covering defects in material and workmanship.
