WILWOOD RACE REAR BRAKE KIT POLARIS RZR 140-17323

The Wilwood UTV6 Rear Brake Kit (Race) is a performance rear braking kit for compatible Polaris RZR PRO XP side-by-side vehicles, designed to provide increased braking force, improved brake feel and greater brake torque for higher-powered UTV applications. The kit combines fixed-mount multi-piston calipers, BP-28 high-friction brake pads and larger floating rotors. Dynamically mounted rotors help reduce thermal stress and prevent piston knockback over rough terrain, while the forged aluminium differential-bore caliper design reduces deflection and promotes more uniform engagement.
