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-205-47 has a 1,500 lb capacity when compressed at 50%. The Black SumoSprings shouldn’t be compressed past 65% 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.

I needed to replace my poor quality, ineffective rear factory bump stops and after much research I felt the SumoSprings to be the answer and selected the recommended SSR-205-47. This product right out of the box proved to be a superior quality product. Install was very straight forward and I completed the install in under one hour. The "unloaded" test drive showed a slightly smoother ride, better small bump compliance, and better control on the high speed road dips that make you feel like you are on a roller coaster. Best of all, cornering saw significantly less back end body roll and a significantly more responsive rear end when swerving side to side. For my particular application - 2017 Chevy Express 3500 - the SSR-205-47, was under approximately 1/2" compression in the "unloaded" state, which was excellent. This contact/compression allowed my unloaded van to ride on the SumoSprings which did make for a smoother, better performing ride over the factory bump stops. It's no secret that these 1 ton vehicles ride rough. The SumoSprings helped significantly to reduce this rough ride. When loaded, I continued to notice all the above benefits. I thoroughly recommend this product. Ride improvement is truly noticeably.
