The original fixed length clutch linkage rod works fine when everything is new, but will not allow proper clutch engagement as parts wear. As the clutch face, flywheel, release bearing and linkage components wear, or when the flywheel is resurfaced, the location of the release bearing in relation to the clutch fingers changes, and the operating rod must travel farther to disengage the clutch. This causes the end of the operating rod to bind and it will bend at the threaded end. This adjustable link eliminates this problem by allowing for you to adjust the length of the link as the wear components go through their normal life.
