EVP UTV Polaris RZR Pro XP and XP Turbo S STM Rage 4 WCP Primary Clutch

Our STM Rage 4WCP Primary clutch features a wider, thicker, more durable spider with new composite spider roller bushings for long life and quiet operation. Utilizing a captured pin with set screws and all-new composite cam arm bushings, it's built for maximum durability and long life in harsh environments and ease of use. We have also added a finned fixed sheave for added airflow and cooler operation.

The included HB series weights are designed for the Pro XP and XP Turbo/Turbo-S specifically. They feature a "humpback" design and offer a good belt grip on the bottom end and awesome mid to top-end performance, especially on higher HP machines.

This clutch can be used with the OEM Secondary Clutch or the STM Billet Tuner Secondary Clutch (Sold separately - Choose from drop-down above)
