Description

The 508 Reaper Cam from Feuling for the Harley M8 motor. Requires high-lift valve springs.

Fits: 2017-2020 Harley M8 Models

  • Produce more power and torque in the riding rpm range, improving throttle response, acceleration and fuel mileage
  • Smooth camshaft lobe ramps are easier on valvetrain components and eliminate excessive valvetrain noise and wear
  • Dyno proven and track tested
  • The Grim Reaper Aggressive pulling power with a nasty sound
  • This camshaft revs up faster than the 521 grind, sounds nastier and pulls harder, but is more difficult to tune
  • The Reaper 508 grind will shine in 114" and larger cubic inch engines with added compression ratio
  • Ported cylinder heads are not required, but will complement the cam and add even more pulling power throughout the range
  • The stock throttle body produces an excellent powerband and use of a high flow throttle body will increase peak power numbers
  • A high-flow exhaust system and air cleaner is highly recommended for optimal performance
  • Feuling recommends matching 508 cam with Race Series®​ oiling system
  • High-lift valve springs are required; see Feuling Endurance BeeHive valve spring kits or High-Load valve springs (High-Load requires the use of Feuling Race Series®​ lifters)
  • Heavy-duty pushrods are highly recommended; see PART #0928-0091
  • 2250 - 6250 rpm range
  • Made in the U.S.A.

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.
