Feuling 508 Cam For Harley Milwaukee Eight 2017-2025 Installation

Feuling 508 Camshaft For Harley

The 508 Grim Reaper offers 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 the race series oiling system. High lift valve springs are required and heavy duty pushrods are highly recommended.

Features:

  • Aggressive puller, optimized for 114" or larger motors
  • 2250-5900 rpm power range
  • Responds well to modified cylinder heads, increased compression ratio, performance exhaust and intake systems
  • High lift valve springs required 
  • High performance pushrods and lifters recommended
  • Made in the USA
