Black Diamond's 10.4 Conversion Kit produces improved shifting characteristics and reduced belt slippage. The 10.4 Conversion Kit's larger outside diameter produces a lower gear ratio at engagement giving the Diamond Drive even a smoother drive away. While at the top end the larger diameter allows for more contact surface area with the belt. The increased contact area minimizes the belt slippage allowing the clutch to run cooler and more efficient. The 10.4 Conversion Kit comes with factory balanced sheaves. You utilize the cam, spring and rollers you already own and reassemble with the new sheaves to complete the clutch. To maximize performance Black Diamond recommends having the assembled clutch balanced at your local dealer. Made in the USA.
*'05-09 models will require two .060" shims to fit properly*
