Feuling Reaper 538 Camshaft

  • 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
  • Aggressive camshaft with a nasty sound
  • Revs up fast and pulls hard in engines with big bore cylinders, modified cylinder heads, intake, compression and exhaust
  • The Reaper 538 grind will shine in 124" 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 Race Series oiling system
  • High lift valve springs are required on stock cylinder heads
  • SE cylinder heads have high lift valve springs, but will need to be verified
  • Heavy-duty one piece pushrods are also highly recommended
  • 2250-6250 rpm range
  • Made in the USA

Questions & Answers

How many will I need

By Ernie P.

I have a 2017 Harley Street Glide. Will I need 2 cams or does this motor only require 1 ?

Only one cam is required for Milwaukee Eight engines. The four cam lobes will service all eight valves on your machine since each pushrod that they actuate are connected to two valves.
