These are a direct replacement bushing and washer that will keep the clutch bolt on centerline. When a clutch is balanced it is based on the concept that you have equal weight all around the center line of the clutch. The stock bushing allows the bolts to move up to .030″ off centerline which puts your clutch out of balance. Our bushing will keep your bolt within .001″ of center. Available in Stainless Steel (35.00) or Titanium (49.00).
