Every SumoSpring is handmade with care, making each one unique with its own natural characteristics, such as slight color variations and surface bubbles, proof of the craftsmanship that goes into every piece.
Front SumoSprings are a maintenance-free suspension enhancement built to create a better journey. Handmade from micro-cellular polyurethane, they are designed to stabilize weight transfer and limit body roll while decreasing vibration, stabilizing sway, and softening harsh rebounds.
The SSF-503-40 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.

Easy to install
I shared my install pics with members of our Newmar Superstar owners group and several have since placed orders for their motorhomes.
Game Changer! Greatly reduced the side-to-side sway of my Freightliner S2RV over rough roads and around turns. Also noticeably reduced the vibration and smoothed the ride. Would be 5 star rating, but I had to modify the driver side bracket to provide clearance from the shock absorber.
easy to install.
Fairly easy to install on the driver's side, but the passenger side was a little more involved due to having to move the positive jump cable attach point and two airlines from the air drier. After the installation, I took the RV for a test drive. I could feel the improvement immediately when I pulled out of our driveway, no rocking like before. On our narrow county roads, the rocking was reduced, easier to maintain my position in the center of the lane. Interstate travel was so much more steady during windy conditions. All in all purchase and installation was worth the cost and installation effort. Thx Ed
