These small parts in this rebuild kit are an easy fix to reduce pressure on your clutch pedal support bushings. The roller bearings allow for a free-moving pedal, and they'll last longer than standard bushings. A new shaft is included as a replacement if your original shaft is scored. This 12 piece kit includes a pedal Shaft, 2 roller bushings, 4 spacer shims, wave washer, 2 plastic bushings, 2 snap rings, and cotter pin.
