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-623-40 has a 1400 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.

These are great. Super easy install. I am running the front and rear bump stops along with an ICON stage 4 suspension set-up with 285/70R/17 AT tires. A week after install I took the 4Runner to Big Bend National Park and ran the back roads that had numerous whoops and washboards. These bump stops are awesome. Made the rebound of the suspension smooth as butter. I was running these back roads between 30-40mph, and the 4Runner stayed “planted” and I never felt as if there would ever be a loss of control. If you are on the fence about purchasing these, purchase with confidence. Ordering was simple and the shipment came sooner than expected.

These are great when going off the beaten path, no more creaking and groaning over washboards. Speed bumps? Smooth as silk. The runner flows over bumps, potholes, and washouts with ease. Love these suspension upgrades!!!

Very helpful when I had questions and I was impressed with knowledge and expertise of your staff. Shipping was on time. I have yet to install the sumo springs and plan to do some right after the new year

They do exactly what I wanted them to do, and that is to support weight when I need it.
