The Tusk Competition Clutch Kit is a high-performance clutch perfect for racing and high heat applications. This clutch is a great choice when replacing wore out and slipping clutches on motorcycles and ATV s. Both the friction and steel plates are made to meet or exceed OEM specifications with tight tolerances to ensure a perfect fit. Instead of being cork based like standard clutch kits the friction plate material is made from an Aramid fiber material which is extremely heat resistant and durable. High strength steel drive plates prevent heat distortion and warping.
