Product details
Listed Polaris RZR 1000 and RS1 rear applications use black six-piston calipers and plain 11.25-inch rotors. Verify wheel fit and the rotor adapter. This UTV conversion combines fixed multi-piston calipers with dynamically mounted solid steel rotors, retaining the specified original hubs. Bill Wood founded Wilwood Engineering in 1977 in Camarillo, California, where the company is based. Wilwood designs and manufactures disc brake systems, producing brake rotors, calipers, master cylinders, fittings, valves and brake lines for motorsport, street-performance and specialized applications. Individual parts are selected to meet the requirements of the complete braking system.

Fitment & Compatibility
Match the Polaris RZR 1000-family and RS1 year/trim rows in the table below before choosing this rear UTV6 assembly. The nonvented steel rotors mount dynamically to adapters on the existing hubs. DS-1500 includes shims for caliper alignment and specifies new supplied banjo bolts and crush washers; the stock banjo bolts must not be reused. Check pad position, wheel shape and the complete range of suspension movement. Aftermarket hubs or suspension parts require a separate clearance assessment, even when the machine is named in the chart.
Rear model coverage includes the listed XP 1000 and XP 4 1000 EPS variants, plus RS1, S 1000 and S4 1000 applications. Later Sport, High Lifter and Ultimate trims are covered only for their specified years. Compare the rear hub and upright on the actual machine; an RZR family name is not a substitute for the complete year and trim row.
