Completely Redesigned!
At 150+ wheel horsepower, the OEM clutches become a liability and are far more prone to breakage. Adding industry leading STM clutching to your vehicle will improve your vehicle's durability and the performance gains will be astounding!
The STM Rage 4WCP Primary clutch features a wider, thicker, more durable spider with a new composite spider roller bushings for long life and quiet operation. Utilizing a captured pin with set screws and an 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 air flow and cooler operation.
The included HB series weights are designed for the Pro XP and XP Turbo/Turbo-S specifically. They feature a "hump back" design and offer 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 the OEM Secondary Clutch or the STM Billet Tuner Secondary Clutch, sold separately.
Includes:
- Billet Aluminum STM Clutch - Fully Assembled and calibrated based on your Vehicle Specs* (Must answer questions prior to adding to cart)
- High Performance Spring
- Retaining Bolt
- Lock Washer
- Bolt Retaining Insert
- Clutch Puller - To remove the STM clutch from the engine
- Weight Fastener Kit - To calibrate the cam arms
- Compression Tool - To change the weights or spring in the clutch without removing it from the engine
*EVP DISCLAIMER: It is the customer's responsibility to ensure that the clutch is calibrated properly for their machine per the instructions provided.
This clutch uses the OEM belt specified for your machine, but you will see improved performance and belt life with EVP's Bad Ass World's Best Belts (sold separately)

Evolution Powersports has a reputation of the utmost quality and attention to detail on every product they design. From within the industry and outside, I have heard nothing but great things about this company and my experience has been the same. If you are looking to make more reliable power this company can get you there. Both customer service and product design are top notch and they stand behind their work!

If you truly want to build your project with the best possible parts available, buy EVO. They not only build with the best materials they test and test to make sure you are getting the performance gains they say you will but that the mods will be safe and keep the reliability of the machine as high as possible. Thanks again to both Jim and Todd. Keep it up guys!
