  • Reverses the rear camshaft’s rotation to provide increased clearance between the cams, allowing higher lifts.
  • High-lift camshafts intended for modified 106" and larger engines, with compression ratios from 10.0:1 to 11.0:1.
  • Improves valve opening accuracy and timing by eliminating timing chain slack and the imprecision of the stock drive.
  • Compatible with stock, unmodified cylinder heads; S&S CNC-machined heads are recommended.
  • Requires material removal from the inside surface of the stock crankcase for installation.
  • Requires a hydraulic press and other professional tools for proper installation.
  • S&S requires the use of an adjustable pushrod and cover kit.
  • Camshaft bearings and seals must be replaced when installing new camshafts.
  • Optimal performance range: 3,000–6,000 rpm.
  • This product is not a bolt-in cam kit.
  • Kit contents: camshafts, inner and outer gears, inner and outer bearings, seals, and installation instructions.
  • Made in the USA.
  • The installer must verify there is no spring coil bind and confirm valve-to-valve and valve-to-piston clearances.
  • Due to the characteristics of gear-drive systems, increased valvetrain noise may occur.
