Wilwood 140-17735 NDPR Rear Brake Kit for UTV, Black, Compatible with Polaris RZR.

NDPR Rear Brake Kit for UTV (Black)

Wilwood NDPR Front and Rear UTV Brake Kits feature dynamic mount rotors and upgraded calipers for popular off-road vehicles. They combine multi-piston fixed mount calipers with increased clamping force and larger diameter, floating rotors for increased brake torque, enhancing braking on high-horsepower UTVs. Forged aluminum four-piston calipers reduce deflection and provide more even engagement for increased braking force and improved feel. High friction steel rotors are up to 20% larger in diameter and thicker for less warping. Dynamic mount rotors reduce heat stress and prevent piston knock-back over rough terrain. Kit Summary
