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

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.
