Gaining the correct engagement is key for overall performance as well as proper launch control. Let your RZR reach its full potential with EVP’s Shift-Tek Ultimate Clutch Kits for all Pro XP and turbo R models, and 2021 XP Turbo/S models.
Available in High Engagement (2600 RPM) or Low Engagement (2200 RPM) packages, these kits are designed and calibrated for better belt life, maximum traction and quicker back shifts. Whether you’re a hardcore racer or everyday duner or trail rider, we’ve got calibrations that’ll keep you on the gas and ensure the best riding experience possible.
- Available in High (notched weights) or Low (straight weights) Engagement kits
- Springs are made from chrome silicon steel alloy, which is stronger than most alloys
- Stiffer primary spring compared to OEM, allowing more belt squeeze to eliminate slippage
- Replacement secondary spring increases back shift speed
- 38-48 Progressive Helix will help eliminate belt slip while adding better grip for smoother back shifts
- Shift-Tek weights feature specific geometry catering to the P90x clutch
- All EVP clutch kits are designed to work with both the OEM and EVP BAD ASS Belts
- Kits are compatible with all RZR Pro XP and Turbo R models, and 2021 XPT/S models only
- Designed, tested and manufactured in the U.S.A.
Pro-XP, Turbo R & XP Turbo/S Ultimate Clutch Kits Include:
- EVP Adjustable Weight SET (Choose High or Low)
- High Engagement: 2400 RPM engagement, notched
- Low Engagement: 1800 RPM engagement, non-notched
- EVP Silver Primary Spring:
- When used with High Engagement (notched) weights, RPM engagement increases to 2600 RPM compared to the stock 1800 RPM engagement
- Low Engagement (non-notched) weights + Silver Primary Spring increases engagement to 2200 RPM
- Silver Spring alone with no weights = 2200 RPM engagement
- EVP Turquoise Secondary Spring: stiffer than stock to allow better belt squeeze, increase back shift speed and eliminate belt slip to reduce heat and eliminate potential blowouts
- EVP 38-48 Helix for Polaris P90X-HD Clutch
NOTE: These clutch kits are compatible with all RZR Turbo R models, 2021+ RZR Pro XP, and 2021 XPT/S models.

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!
