S&S, M8 chain driven 550C camshaft kit

Horsepower cam for 114 and larger engines. On the S&S dyno a 114" Street Glide with a Stealth air cleaner and Power Tune dual headers with Mk45 mufflers was good for 120 HP. 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 printed or online Motorcycle Storehouse catalog for the S&S camshaft specification chart.
