1/4" Rear Overload Springs - Fits 15-19 Outback

Whenever you are installing a suspension lift on your 15-19 Subaru Outback and carrying extra weight, RalliTEK overload springs are the best spring to use. Our exclusive dual-rate linear coil spring technology enhances off-road performance while allowing your lifted Subaru Outback to carry more weight and accessories while increasing ground clearance and reducing the dreaded Subaru “sagginess.” 

No matter what weight you're loading your overload springs with - rooftop tents for overlanding, bumpers for hardcore off-roading - our Subaru overload lift springs can handle the capacity. With our proprietary spring technology, we improve off-road handling and predictability while maintaining Subaru's plush on-road ride quality. As a result of our lift springs, larger tires can be fitted for enhanced stability in inclement weather or on difficult terrains. Our suspension lift kits are equally at home in the hills, on the overland trails, in the snow, or on the interstates.

  • Estimated lift: 1/4"
  • More responsive handling and turn in
  • Increased approach and departure angles
  • Extremely improved off-road performance
  • Maintains factory on-road ride quality
  • Increases ability to carry more weight on the vehicle
  • Rear Spring rate: 355 lb/in
  • 30% stiffer than OEM
  • Lifetime warranty

RalliTEK Overload Springs

The springs in combination with Bilstein B6 shocks raised my 2018 Subaru Outback (105,000 mile) to its normal stance. Headlights seem normal and I am no longer getting flashed on low beam. The alignment seems fine too, but I will get it checked anyway. Handling is much better particularly on sharp turns, and off-road absorption does not seem too firm. Very happy!

These springs changed the way the car handles. Makes a very noticeable difference. I installed these before a 3500km roadtrip camping all throughout the northeast US. The ride was comfortable and not soft. Paired with bilstein b6's and an STI sway bar it has greatly reduced understeer and makes cornering way more crisp.

Sag is finally gone!

I replaced the rear springs of my 2017 Outback with the RalliTEK Overload Springs a couple of months ago, and what a difference. Fully loaded car with 4 bikes on the back, and the sag was barely noticeable. Kept the original shock absorbers, and it is working fine, not getting any significant bouncing. I should have done this many years ago...

1/4" Rear Overload Springs

Very satisfied with these springs. I Paired these with the Bilstein B6 struts on my '15 Outback. There was nothing perceivably wrong with my stock springs or struts after 115k miles, but Outbacks are known for getting a very saggy butt even when loaded with just a few hundred pounds. These springs have completely taken care of this issue. I recently took the Outback on a multi-day car-camping/snowboarding trip with it fully loaded and it was so nice to not feel like the rear end is about to bottom out on every bump or dip in the road. As far as overall ride quality, I would say the vehicle feels more planted on the road and is less affected by wind gusts or passing semis. The springs and struts are noticeably stiffer, which makes some small features in the road feel more pronounced, but I would take that any day over not being constantly bucked around when driving over larger features with the stock

Worked Great!

The overload springs were exactly what I needed to prevent sag in my outback when loaded down or towing a small trailer.

Love the ride

Rides great, towed a uhaul trailer last week with zero sag in the rear end. Kinda wish I had gone with 0.5” or 0.75”lift spring.

Great upgrade for the adventure wagon

Springs greatly improved handling and ride height when loaded up with gear. Stoked on this upgrade!

Should be standard from Subaru

I was looking for solution to crosswind issue (felt like front and rear suspension not connected) and porpoising over large bumps. At first tried King Springs but they are meant for off road, too hard for everyday driving. I went back to OEM front springs plus RalliTEK overload springs and Bilstein B6 struts. The car handles great on mountain roads, more stable in crosswinds and the porpoising is gone.

Made a world of difference

I purchased the front and rear springs for my 2017 Outback to improve the ride height and stability when towing our tiny trailer. There is noticeably less sag in the rear end and better control with the new springs -- well worth the investment.

Works a treat!

Helper a lot with towing a popup trailer with a Subaru outback and even seemed to help with the cars factory understeer.

Those spring will work without the lift?

RalliTEK

These springs do provide a 1/4 inch lift from the spring alone, and require no other supporting components!
