We have been testing various clutch weight designs for months and have settled on what we believe is the best profile to get the power to the ground and keep the rpms under control. The EVOPS RZR XP TURBO kit consists of 3 custom ground adjustable weights and shims for both the primary and secondary clutches. These weights are super aggressive. The spring shims help to optimize upshift and backshift. We have setups for Stages 1-5. Kits should be ready to ship by late next week. We will post driftbox data of the kit showing substantial 0-60 time reductions vs stock shortly. Kits will be up on our website this weekend.
