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-114-54 has a 2,800 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.

Installed This kit on my F250 Super Duty before my last trip towing a 35ft 5Th wheel trailer. Nice level smooth ride. The spring compressed about halfway and still had a great ride. I feel a lot safer towing with this kit. Very happy! I did not want to have air bags and all the hard ware and air. With SumoSpring I never have to think about it again. No air needed, no worries about air bag failure and no worry about having air available.
