Feuling Reaper 521 Chain Drive Camshafts

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.

Made in the U.S.A.

Aggressive pulling power with a nasty sound, the Reaper 521 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.

Stock throttle body produces an excellent powerband; use of a high flow throttle body may increase peak power numbers.

A high-flow exhaust system and air cleaner is highly recommended for optimal performance.

Feuling recommends matching 521 cam with Race Series oiling system PART #0932-0199.

High lift valve springs are required on stock cylinder heads; see Feuling Beehive valve spring kit PART #s 0926-2973 or 0926-2974 on page 700.

Heavy-duty one-piece pushrods are also highly recommended; see PART #0928-0091 on page 703.

RPM range 2250 - 6250.
