S&S, M8 chain driven 540C camshaft kit

Torque cam designed to offer generous pulling power up that hill; or quickly passing a big rig in traffic for big bore motors. Real life touring power below 6000RPM but still good for respectable HP numbers. Kit includes cam; all required bearings; o-rings and hardware. Gear drive cams provide improved valve timing accuracy but more mechanical sound; when compared to chain driven cams. The additional mechanical sound is the reason why OEM runs chain driven cams. Note: This is a small base circle cam. Requires adjustable pushrods and heavy duty valve springs. S&S Recommends 558660 Quickee pushrod & cover kit and 565784 S&S .605" heavy duty valve Spring kit. Note: For best performance it is; like with all performance cams; recommended to use a free breathing air cleaner and exhaust system. Note: With each cam change S&S recommends their 583903 Precision tappet assembly set. Note: See paper or online Motorcycle Storehouse catalog for the S&S camshaft specification chart.
