M8 chain driven 475C camshaft kit

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.
