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.

SumoSprings Builder Kits are for the DIYers out there. They require custom mounting and can be used in front or rear applications. These SumoSprings are 5" tall and 4" in diameter and can be installed by themselves or with one to two off the 1" spacers. The DIYer will need to supply the hardware and bracketry for this installation.
