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-217-47 has a 1,500 lb capacity when compressed at 50%. The Black SumoSprings shouldn’t be compressed past 65% 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.

Had no problem ordering them and easy to install.
Towing is improved, love the level of the truck no when the bed is loaded, and the trailer is connected. I initially installed the 1" preload spacer, and that wasn't for me at all - changed the level of my trailer and truck. I'll bet that spacer is for the Trail Boss models, not the basic off-road package. Maybe that could be included in the literature if that's the case. Very impressive product. Looking forward to adding some of these to my travel trailer.
