Fitment & Compatibility
The table below includes the listed Polaris RZR XP 1000, XP 4 1000, S 1000, S4 1000 and RS1 configurations with year-specific trim coverage. The front conversion requires the upright grinding shown in DS-1499 for pad clearance. Reuse the factory hubs with the dynamic steel rotor adapters and use the supplied banjo bolts and crush washers. Do not reuse the original banjo bolts. Check the actual wheel section, at least 0.080-inch caliper clearance and the hose path through steering and full suspension articulation.
