The 405 Reaper Cam from Feuling for the Harley Softail M8 motor. A direct bolt-in replacement that can be used with stock valve springs, pushrods, lifters and exhaust.
Fits: 2017-2020 Harley M8 Models
- Will respond well when used with slip-on mufflers or full exhaust system and a high-flow air cleaner
- Produces a wide powerband that increases torque and horsepower throughout the entire rpm range
- 1700 – 5700 rpm range
- Direct bolt-in replacement for M-Eight engines; can be used with stock valve springs, pushrods, lifters and exhaust
- Feuling recommends mufflers with smaller cores for the best low-rpm power
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 cam/valve 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.
