Description:
Wilwood's UTV4 Race brake kits feature dynamically mounted rotors and upgraded calipers for popular side-by-side machines. Kits combine fixed mount multi-piston calipers with greater clamping force, BP-20 (high-friction) brake pads, and larger diameter floating rotors for more brake torque—improving braking on higher-powered UTVs. Forged aluminum differential-bore 4- and 6-piston calipers reduce deflection and provide more uniform engagement to increase braking force and improve feel. High-friction steel rotors are up to 20 percent greater in diameter and thicker for less distortion. Dynamically mounted rotors reduce thermal stress and prevent piston knockback from rough terrain.
