Total Price: $567.98

Rear SumoSprings are a maintenance-free suspension enhancement built to create a better journey. Handmade from micro-cellular polyurethane, they are designed to reduce rear-end sag and increase load carrying ability while decreasing vibration, stabilizing sway, and softening harsh rebounds. 

The SSR-612-40 has a 1,400 lb capacity when compressed at 50%. The Blue SumoSprings shouldn’t be compressed past 70% of their original height in order to keep full memory rebound.

Please Note: SuperSprings International products are specifically designed for vehicles equipped with factory suspension. We cannot guarantee their compatibility with aftermarket products or parts. For questions about fitment on your specific vehicle, please contact us.

2018 Tacoma TRD Sport 2wd, i have a camper shell on the truck and it the ride feels much better, smoother I would say and more stable. Very easy to install in just a couple of minutes

I put these on my 2016 frontier to help with hauling my 870 lb 4 wheeler. With these the truck is almost level when loaded and it helps a bunch when driving. Much better control and I still have a bit of travel to help absorb the bumps. When unloaded there is about a 1" gap and you cant tell there there under normal conditions. In a work EXCELENT.

Really impressed with ride

I bought a pair of these for my 22 Toyota SR5 dbl cab long bed 4x4. I added a Leer 122 canopy and noticed roll when taking corners afterwards. The install went easy and the body roll is gone, smoother ride, and potholes are much less of an impact.
