This is a must-have modification for your tuned RZR XP Turbo! Clutching is everything, especially when you add power to your machine. To properly transfer added horsepower you need to adjust your CVT clutch. Our custom weights were designed to help shift the clutch harder, resulting in more power to the rear wheels. These Goldstar magnetic adjustable weights have been a customer favorite as they are very easy to adjust and work so well. This Stage 2 also comes with our primary spring, secondary spring & custom cut helix which helps hold side tension on the belt for less slip and quicker backshifts. All around, this kit adds huge performance and will help the belt life, belt smell, and clutch life of your XPT. When installing make sure you remove your primary limiter which is the grey plastic washer between the spring and the clutch. Many will also cut down the secondary limiter nipple to half the size for more shift out. With this removed and BMP custom tuning, you can see over 90 MPH! The kit comes with a full setup guideline that will let you know how to properly adjust the weights for your tire size and other modifications.
