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-329-47 has a 900 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.

The teams help to get the product before my trip was awesome. Installation was super easy. The ride difference is amazing. Did a 1,600 mile trip right after install with 11 passengers, hauling a small trailer and loaded to the ceiling. Handling and ride was awesome!

Super Springs was really helpful and shipped it out quick. The ride improvement was great, feels solid and the swaying in and out of driveways has improved immensely. Just a much more solid ride.

Order, shipping, communication was outstanding. Installation was much easier than expected. Replaced all bump stops in less than 45 minutes!
