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-203-40-2 has a 3,000 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.

Truck rides a little stiffer when unloaded, but when loaded or towing my enclosed trailer and mainly my 5th wheel, we notice a major difference. We will be ordering a set for our 5th soon.
Superb product!
So far so good - product has been on for four days and k my towed fifth wheel once- impressive
Purchased the SSR-203-40-2 during your sale back in November and just installed them today on my Silverado 3500 dually. I can't believe I waited so long. Thought we didn't really need them until we bought our 5th wheel RV but I was wrong. What a difference in the smoothness of the ride. This product should be standard form the factory!! I can't think of any downside to have these on every HD truck! Can't wait for your next sale so I can buy 2 pair for the 5th wheel trailer. If you ever run into anyone who is on the fence on buying these let me know. I would be more than happy to set them straight! Great product.
Quick delivery. Easy instal. Noticeable improved ride.
Received springs pretty quick. Mounting went ok except emergency brake cable on right side was fastened in the way to install j-hook
A little tricky with the install. Rear brake line RR in conflict with hook bracket. RL brake line passes over studs and nuts, friction on brake line a concern. Extremely happy with product. Used with cab over camper. Camper remodel at Grasslands, BLM areas, and forest roads. 4WD accessible public lands. Sumos made a big difference on washboard and rough roads, road haves and reasonable sway situations. I called and spoke to a friendly and knowledgeable salesman and followed his recommendations. I'm very glad I did.
