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-116-40 has a 1,000 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.

Easy installation took the sag out when empty rides well haven't had a chance to try it under load yet but I'm confident it will perform as expected
I originally used the SSR-116-47 on my F-150 but noticed a much harsher ride when unloaded. I switched to the SSR-116-40 and it is night and day better unloaded and much better than stock with a large payload. The 40's assist with the load without changing the unloaded ride characteristic. With a 1500 lb load, I have no body roll and the entire truck/fifth wheel combo feels stable and solid. This is a great product from a fantastic company with great customer service.
