Description
S&S Camshaft Kit for Harley Davidson Milwaukee Eight
Camshaft installation for HD M8 including all required bearings, o-rings and hardware. Gear drive cams comes with all gears required to convert from chain drive. The gear driven cams provide improved valve timing accuracy and more mechanical sound, when compared to chain driven cams.
For best performance it is, like with all performance cams, recommended to use a free breathing air cleaner and exhaust system.
With each cam change S&S recommends installing their precision tappet assembly set. Although only required for 540, 550 and 590 we highly recommend replacing the pushrods with S&S Quickee pushrods as it will save you massive amounts of time. This is also a good moment to upgrade from the stock plastic tappet anti-rotation devices to S&S billet aluminum tappet cuffs as these capture the tappets without impacting vertical motion and keeping them perfectly aligned, even in high stress, high RPM situations.
