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-146-40 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.

Even though we have one of the best hitches, we still had some porpoising when towing our travel trailer. After having the Sumo springs installed, it's gone, and the ride of the truck feels more like a truck should instead of like the bouncy ride of an old Cadillac. Very glad we purchased these springs instead of going the expensive air bag route.
Significantly reduced rear sag to almost unnoticeable when towing travel trailer. Better ride and control. Guy with same truck and similar trailer stopped me when leaving campground and asked me how I got everything so level. Highly recommend.
Took the endless bounce out of the suspension when pulling the boat. Truck will corner with much more confidence and less roll in the front end.
Awesome product as always!
Significant improvement in bounce improvements in brake response as well
Working with the tech to make sure I got the right sumo springs was really helpful. Install was quick and easy. Immediately I notice improved ride quality and handling. And no more squat with the trailers.
