  • SumoSprings Part Number SSR-610-40
Total Price: $567.98

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-610-40 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.

They have made a difference in the handling of each and I am glad I did this. I got them on the Black- Friday sale and saved a lot. They are easy to install and did my motor home in under a hour for front and back. This cost under $400 and the shop wanted around $1800. So each the videos and do them yourself.

Easy installation that works great with a gooseneck hitch. If they last I’ll be happy…

Great fit and easy installation at a great price. Attach a trailer, load it heavy, and go with little to no sag. All my trucks in my business will have these installed.

Very easy install and works great

Extremely easy to install on my 2011 Nissan Frontier 4x4. I lifted the bed by placing a jack under the tow hitch and that gave me plenty of room to install the sumo springs. Once I let the bed down, there was no clearance between the frame and sumo springs, but it does not seem to have affected the ride much. It does look like it raised the back end maybe an inch or so compared to before the install. I did hook up the travel trailer and the Sumo springs did their job and kept the truck from squatting as much as it did before.

Installation was straight forward, took about an hour per the instructions provided. Springs are in place with about a quarter inch clearance on a truck with a Shell and 200 lbs gear in place. Have not towed with them yet.
