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.
The rear six-piston caliper uses 1.00-inch piston bores and BP-10 compound pads. The mounting kit includes shims for setting the caliper position relative to the rotor. Verify alignment and pad clearance before securing the banjo connection and testing suspension movement.
