The Clutch Masters Master Cylinder Upgrade Kit replaces the factory clutch master with a 6061 billet aluminum unit featuring a 0.700 inch bore for firmer, more consistent hydraulic actuation under aggressive driving. It deletes the factory clutch delay valve for faster, more direct engagement. The black anodized kit includes a billet master cylinder with adapter and jam nut, a billet remote reservoir with mounting bracket and hose, an extended adjustable pushrod with billet clevis, banjo fittings with crush washers, and a jam nut tool.
