SUMO SPRING REAR BUMP STOPS - SPRINTER (1994+ 2500 ONLY) PAIR
SUMO SPRING REAR BUMP STOPS - SPRINTER (1994+ 2500 ONLY) PAIR
SKU:SSR-325-47
The Sumo Spring replaces the factory rear bump stops. It contacts the rear axle sooner to increase the rear suspension spring rate while still compressing to the height of the factory bump stop. Suspension travel is not reduced. The additional spring rate reduces sway, improves control in high winds and comfort while the suspension cycles. Recommended for vans that carry heavy loads most of the time or tow trailers. The additional spring rate will reduce rear suspension sag when loaded. These pair great with our rear tuned Falcon shocks for a complete change in ride dynamics.
All SumoSprings are manufactured from proprietary closed microcellular urethane with materials density, tensile strength, elongation, tear resistance, rebound, and compression characteristics designed specifically to suit drivers applications. Made in USA.
I had wanted to install the mini spring pack but they were incompatible with my mono leaf suspension. Wasn't interested in a full spring replacement given most of my travels are going to be highway and I just want to bring a little stability to my near-GVWR van. The Sumo springs turned out to be a great solution. I could tell a difference as soon as I pulled out of my driveway. Between these and the Falcon shocks I have much fewer Crosswind "Assist" episodes and the ones that I do have are much less aggressive.
These are a simple, yet effective improvement for Sprinters. I put them on my '16 4X4 and noticed the difference immediately.
They were actually harder to put in then the fox shocks I put in at the same time. It took quite a bit of muscle to squeeze them in. I could tell a difference right away leaving the parking lot at the curb cut that usually even makes everything in the van shake crazy, also taking corners there’s a big improvement. When I let the weight back down on the axle the rubber of the sumo spring was with in a 1/8” of cupping the axle, so any movement and it comes in contact. I think these paired with the shocks are a must for a 170” sprinter that carries a heavy load.
