Feuling 508 Cam For Harley Milwaukee-Eight 2017-2026 Installation

Feuling 508 Camshaft For Harley

The 508 Grim Reaper delivers aggressive pulling power with a hard-edged exhaust note. It revs faster than the 521 grind, hits harder and carries a more demanding tune. The 508 Grim Reaper performs best in 114 cubic inch and larger engines with increased compression. Ported cylinder heads are not required, but they complement the cam and add pulling power across the range. The stock throttle body provides an excellent powerband, while a high flow throttle body can raise peak power. A high flow exhaust system and air cleaner are strongly recommended for best performance. Feuling recommends pairing it with the Race Series oiling system. High lift valve springs are required and heavy duty pushrods are strongly 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
