X300 Clutch Kit

The KWI X300 Clutch Kit is a purpose-built performance clutch upgrade for Polaris RZR XP and Turbo platforms — engineered to deliver maximum performance, precision, and adjustability without unnecessary extras getting in the way. If you want consistent RPM control, stronger belt grip, and smooth backshifting across every terrain, this is the kit that delivers it.

Each kit includes (3) X300 Adjustable Weights, a White Secondary Spring, and a Magnet Pack — custom-tuned in-house by KWI for the XP and Turbo platform. The fully adjustable weight system gives you real tuning control over engagement, RPM range, and power delivery for your exact tire size, terrain, and riding style. Whether you're pushing dunes, crawling rocks, or charging wide-open desert, the X300 keeps torque and power right where you need it.

The X300 Kit restores lost power, eliminates belt slip, and delivers a more responsive throttle feel — for high-performance builds and daily riders alike. Straightforward to tune, proven on the platform, and built to perform every single ride.
