Description

Product Description

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

Fits: 2017-2024 Harley M8 Models – (Excludes VVT 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 PART #0932-0199
• Requires high lift valve springs; see PART #0926-2973 or 0926-2974
• 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.
