S&S, M8 chain driven 590C camshaft kit

All out high RPM horsepower cam for 124" and larger engines with monster bores and ported heads. The high lift allows maximum breathing right into the horsepower spitting RPM range. On the S&S dyno a 2018 Fat Boy with a 131" stroker kit, 68mm throttle body & Stealth +1 air cleaner gave 146HP @ 6200RPM and 112.58 torque @ 4700 RPM. 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 the paper or online Motorcycle Storehouse catalog for the S&S camshaft specification chart.
