Description: These Teflon shims can be used in place of the metal washers usually put between the clutch shoes, and the flywheel. They space the shoes off the face of the flywheel to prevent hang-up when the shoe sides bur. One shim can last up to 4 gallons of fuel with proper clutch maintenance! They are more convenient than three small, metal washers when you are doing clutch maintenace. Since they're Teflon they also eliminate the wear to the face of the flywheel caused by metal shims. They provide a surface with very little friction for the shoe to pivot on. They are available in quantities of (1) shim for $2.50/pack and (4) shims for $8.00/pack. Bulk quantities are also available in quantities of (50) or more. Note: Fits Associated, Mugen, Sportwerks, Kyosho, CEN Matrix, & OCM Flywheels
