Since you're here, add the front solution too.
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-338-54 has a 1,400 lb capacity when compressed at 50%. The Yellow SumoSprings shouldn’t be compressed past 55% 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.

Removed air Suspension installed spring suspension. Works great no more air leaks.
Worked great. Took the sway and rock out of it. Very pleased.
Great products and good support. Thank you.
Huge improvement in ride, handling, and sway reduction
The package came sooner than I thought. I watched the video that Super Springs has for putting the springs on the chassis. The video made it look easy..I got my buddy and we followed the instructions on the video..In about 40 minutes with two total amateurs the Sumo Springs were on. The Wayfarer came with the Black Sumo springs. I replaced the Black with the Yellow Sump Spring. There is a big difference between the springs. So far I really like the Yellow Springs. I am waiting for the first of the year to come...Super Springs is supposed to have a new bolt-on helper leaf spring.
Seemed to help sway.
When I first bought the RV it really swayed badly going up drive ways. Driving on the freeway was bad on cross winds and when semi’s. I needed something so I bought the sumo yellow what a difference. Love them
Made dramatic improvements
Vast improvement in ride, stability and handling. Cornering extremely improved. Fairly easy to install even with all the extra components tucked into the chassis.
Easy order and install
SumoSprings have made our van handle much better - flatter through corners and less swaying over low speed bumps.
