The Koso spring slider comes complete with base plate, spring holder and ball bearings. The design of the spring slider prevents spring wind up and distortion of the rear clutch compression spring that occurs when the rear clutch shifts in and out causing the spring to twist.

Without the spring slider, the compression spring will eventually become loose and deformed causing the spring tension to change. We recommend that this part is purchased and installed with the rear clutch compression spring.
