Bolt-in 100 HP cam. Compatible with all stock components but requires free-breathing air filter & exhaust mufflers. With each cam change S&S recommends their 583903 Precision tappet assembly set. 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: 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.
