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.

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

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!
