Feuling Reaper 508 Cam for 2017-2024 Harley M8*
NOTE Due to the unstable nature of this 4-valve engine design with one rocker arm activating two valve springs, Feuling highly recommends running one-piece pushrods over quick-install adjustable pushrods to maintain maximum camvalve lift and reduce valvetrain harmonics and associated hydraulic lifter issues.
NOTE Feuling fastener kit PART #3047 also highly recommended to help prevent cylinder head cracking; kit replaces the rocker shaft bolts with studs and nuts to help reduce the stress of the rocker shaft standoffs.
