Every SumoSpring is handmade with care, making each one unique with its own natural characteristics, such as slight color variations and surface bubbles, proof of the craftsmanship that goes into every piece.
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.
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.

We don’t drive our Revel on awful roads. We do use it on wash board, rough dirt roads. The summo springs have greatly improved the “rock and roll” tendency of our RV, thanks for a good product.
The combination of Sumo and SuperSpring have made a great difference in the ride quality. They have basically eliminated body roll and soaks up potholes and large road depressions like they weren’t even there. The van rides like floating clouds
The ride is much more comfortable. Especially on the highway. When hitting pot holes at high speed the rear of the vehicle does not bounce. I also noticed that it has improved stability on winding highway.
Easy install and instant, noticeable improvement in ride and handling quality
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!
