Drive clutch springs are in constant motion, being subjected to compression, rebound, end to end radial torqueing, distortion and vibration. "Glide Washers" are custom made with a baked-on lubricity coating. By placing a washer on each end of the spring, it can no longer bind on the spider or clutch cover. This frees up the spring to do its intended job. Each kit comes with 5 washers. Two have a lubricity and rust proof coating and three are zinc plated to prevent rust. Each washer increases clutch engagement speed approximately 40 to 50 rpm's which makes it an excellent tuning tool. Made for Polaris & Arctic Cat.
