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-217-40 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.

The blue one added a slight lift without sacrificing the ride

Excellent order processing. My order was shipped much sooner than estimated ship time when I placed the order. Just completed an 800 mile round trip with my new SumoSprings installed on my trailer. The improvement in ride and towing experience is remarkable. This is the best modification to my trailer yet. If I buy another trailer SumoSprings will be the first thing I install.

I recently purchased the SSR-217-40 for my 2020 Chevy Trailboss. They arrived in 3 days (CA to VA) and I was very impressed with the shipping speed and happy to receive them. I put them on last night and everything went on and fit as expected. I did use the optional 1" spacer, but have yet to load it down. I expect I will leave the spacer to help with a faster preload. I installed them by myself in about 30 minutes in my driveway and jacked up my truck with a floor jack under my drop down trailer hitch. Lifting the rear end as high as I could without taking the tires off the ground gave me plenty of clearance. The kit came with everything needed, down to a small tube of blue locktite.

Great product, had the same set up on my 2014 Toyota Tundra and have been really pleased with the springs.
