"Thank you guys for these unique products. I couldn't imagine being able to fit a 33.3" without any lift/level. However, these Coil SumoSprings are far much better than any level in the market. The ride became different, with more stability at the front. They have eliminated the vibration on gravel terrain without deflating the tires."

Something for everyone.

If your vehicle has coil suspension, we have options.

Coil SumoSprings are made from the same material as our other SumoSprings products – a micro-cellular polyurethane that decreases vibration, stabilizes sway, and tightens up your existing factory coils. This upgrade adds up to 30% additional capacity to your coils, creating a cushion effect and stopping unwanted dip and roll.
