Suspension you can't destroy. Even if you try.
Manufactured from our micro-cellular polyurethane, the 4Runner SumoSprings suspension kit is designed to reduce rear-end sag, decrease vibration, and soften harsh rebounds on every adventure.
With zero-maintenance, these airless air springs increase overall ride comfort and were designed to outlast your truck.

"Overall, we are extremely impressed with the quality of these SumoSprings. We replaced our Timbren bump stops (a very reputable company) with a set of these Blue SumoSprings on the rear of the white 4Runner."
