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-204-47 has a 900 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.

Even with a 3500, the steering improved on the front.

The sumosprings have really improved the ride on corners - no more sway!

I needed to replace my poor quality, ineffective factory bump stops and after much research I felt the SumoSprings to be the answer and selected the recommended SSF-204-47. This product right out of the box proved to be a superior quality product. Install was very straight forward and I completed the install in approximately one hour. The test drive showed a slightly smoother ride, better bump compliance, and better control on the high speed road dips that make you feel like you are on a roller coaster. Best of all, cornering saw significantly less front end body roll and a significantly more responsive front end when swerving side to side. I thoroughly recommend this product. Ride improvement is truly noticeably.
