Wilwood 16-21 Polaris RZR XP 4 Turbo Rear Kit 11.25in Drilled Rotors - Black
Wilwood’s matched front and rear UTV 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, and larger diameter floating rotors for more brake torque, improving braking on higher-powered UTVs. Forged aluminum differential-bore four and six piston calipers reduce deflection and provide more uniform engagement to increase braking force and improve feel. High-friction steel rotors, are up to 20% greater in diameter and thicker for less distortion. Dynamically mounted rotors reduce thermal stress and prevent piston knockback from rough terrain.
