Wilwood 140-17735-R NDPR Rear Brake Kit, Red, for Polaris RZR

NDPR UTV Rear Brake Kit (Red)

Wilwood NDPR UTV Front and Rear Brake Kits include dynamic mount rotors and enhanced calipers for popular off-road vehicles. These kits combine fixed mount multi-piston 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 warpage. Dynamic mount rotors reduce thermal stress and prevent piston knock-back over rough terrain. Kit Summary
