Wilwood 2014+ Polaris RZR XP 1000 Rear Kit 11.25in - Black

The Wilwood 140-16633 UTV6 Rear Brake Kit upgrades braking for Polaris RZR XP 1000, RZR XP 4 1000, RZR RS1, RZR S 1000, and RZR S4 1000 models. It features fixed-mount multi-piston calipers for increased clamping force and larger 11.25-inch floating rotors for enhanced brake torque, ideal for higher-powered UTVs. Forged aluminum, differential-bore calipers ensure uniform engagement. High-friction steel rotors (0.25 inches thick) minimize thermal distortion and prevent piston knockback. The kit includes black powder-coated calipers and plain face rotors. Alternative options (140-16633-D, 140-16633-DR, 140-16633-R) offer drilled rotors and red calipers. Compatible with factory master cylinders, ABS, pedals, and most 15-inch+ wheels (some 14-inch).
