The stock clutch is made from cork material. This is a very soft and quickly deteriorating material. When your clutch is slipped the fibers create friction and heat. That heat breaks down the cork very easily. Our fibers will allow your clutch to get much hotter before the material begins to break down. This gives you a much more reliable clutch. When combined with our 6 spring conversion we have pushed this clutch to 500 horsepower reliably with better than stock driveability. There is no warranty on clutch parts. Be sure to install and adjust the clutch correctly - follow the ATV manufacturers service manual for your ATV.
