Product details
This RZR front race conversion uses UTV6 calipers with 1.25/1.12/1.12-inch piston bores and 11.25-inch solid steel rotor rings. Dynamic rotor adapters fit the retained front hubs. Anodized calipers and 11.25-inch plain face rotors are the selected configuration. Founded by Bill Wood in 1977 and based in Camarillo, California, Wilwood Engineering designs and manufactures disc brake systems and components for motorsport, street-performance and specialized applications. Its range includes calipers, brake rotors, master cylinders, valves, fittings and brake lines, chosen to match the complete system.

Fitment & Compatibility
Read each RZR XP/XP 4 Turbo, Turbo S and PRO XP/PRO XP 4 entry independently, including EPS, DYNAMIX, Fox, Velocity, Orange Madness, Sport, Premium, Ultimate and Rockford Fosgate versions. Front mounting and hose routing must match the documented installation; do not assume that every RZR year or rear kit is interchangeable. Use the complete application table below to check the individual year, model, submodel, original brake configuration and attached notes.
PMB Performance brings 20+ years of parts and fitment experience to brake selection. Send the actual hub or spindle details, existing brake configuration and wheel measurements for help checking this combination.
