  • With hundreds of hours of testing on each cam, you know you are getting the best cam S&S can produce

  • Requires high-lift springs
  • Less overlap and fast ramps build higher cylinder pressure
  • Lower TDC lift makes installation easier
  • Designed for use with hydraulic tappets
  • Installer must check coil bind, valve-to-valve clearance, valve-to-piston clearance and cam lobe to case clearance.
  • Made in the U.S.A.
