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-111-47 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.

Absolutely Amazing!!!!!!!!! Couldn’t believe how much better the truck rides. Makes my daily commute of 250 miles so much more enjoyable. The sumo spring are the best money I have spent so far on this truck and I have over $25,000 in upgrades on my truck. Honestly I have been telling everyone about them! Thank you for a great product and excellent customer service!! Any wait to put them on my travel trailer!

We have only driven to the gas station to fill up for our next trip but can already tell they are going to help.

15’ F350 powerstroke 9’6” stainless XV2 This product surpassed all expectations! Greatly reduced body roll, hits potholes like a half ton, and got rid of all the suspension sag from the plow. Easy 20 minute install. Extremely happy with this product, I’ll be ordering the Sumo rears very soon.
