Description

Designed for high performance engines with cylinder bores between 4" and 4 3/8".

Features & benefits

  • Fits: 1984-'99 big twins with 4" bore and over
  • A ported breather passageway and a machined breather window allows the air/oil mist to flow from the flywheel cavity to the cam chest of the engine with the least possible restriction
  • Crankcase venting can be achieved via two crankcase breathers, the cylinder heads, or both! We recommend using both crankcase breathers in engines larger than 95"
  • Relocated cam chest oil pick-up increases gear case scavenging and virtually eliminates oil carry-over at sustained high speeds
  • Cam chest is moved outward .250" to allow crankcases to handle large cylinder bore sizes
  • Machined to accept the stock oil filter assembly used on 1992-'99 big twins
  • Fits: S&S 4" bore: V100, V107, V113, V107T
  • Fits: S&S 4 1/8" bore: V124, V111, V117
  • Clearanced for strokes as long as 5"
  • Fits: S&S 4 3/8" bore: V126
