FEULING PARTS Race Series 508 Camshaft Kit - Harley-Davidson '17-'24 - 1459

FEULING camshaft kits for Milwaukee Eight engines include chain drive camshaft, lifters and a cam installation kit that includes cam bearing, cam/crank hardware and a gasket/O-ring kit that allows for install of the factory one piece pushrods and or our optional and recommended heavy duty HP+ 0.165 wall one piece pushrods - see # 4087

Feuling fastener kit #3047 is also highly recommend to help prevent cylinder head cracking, this kit replaces the rocker shaft bolts with studs and nuts to help reduce the stress on the rocker shaft standoffs.

HP+ kits come with HP+ lifters and RACE SERIES kits come with RACE SERIES lifters
508 CAM - 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 this cam with our RACE SERIES oiling system #7097.

NOTE: High Lift valve springs are required on stock cylinder heads, see FEULING BEEHIVE valve spring kit #1107 (DRAG# 0926-2973) or #1108 (DRAG# 0926-2974). SE cylinder heads have high lift valvesprings and will accept the 521 grind cam. Heavy Duty one piece pushrods are also highly recommended see #4087.

RACE SERIES hydraulic lifters have a full .200 of total travel designed with a slower bleed down rate to handle heavy valve spring pressures, increase engine RPM before valve float and feature increased roller clearance for steep ramped camshafts and clearance for the Milwaukee Eight front exhaust camshaft lobe flange.
