These high performance clutch kits are designed to drop into the stock clutch basket yet provide increased clutch friction area and smooth, linear engagement. They are supplied with 3 sets of coil-type clutch springs that allow you to tune your clutch to any engine performance from stock to extremely wild and anything in between. Kits feature a billet aluminum clutch pressure plate with a steel liner plate, extra wide friction discs for maximum contact area and matching extra wide steel clutch discs. Installation requires small modifications to the inside of the inner and outer primary covers.
