Aftermarket Assassins - Polaris RZR Pro XP / 4 Pro XP S3 Clutch Kit

Note: Does not fit 2021-up models as the helix design changed.

The S3 recoil clutch kit is one of the first modifications you should make to your Pro XP. These kits deliver aggressive acceleration and instant clutch response across all terrains—whether on the trail, at the race, in the dunes, or mudding. You'll experience wicked acceleration, better RPM hold on climbs, reduced bogging, and improved wheel speed.
