🔧 Easy-start cam kit engineered to reduce compression only at initial cranking, then restore full compression as RPM rises for normal operation without loss of performance.

✅ Designed as a bolt-in solution for 103" engines, delivering more usable power across the rev range with best results from 2500–5500 rpm.

  • Includes camshafts, gearcover gasket, bearings, retaining ring, o-ring, thread locker and instructions.
  • Works with stock, un-ported heads and performs well with S&S CNC ported heads.
  • Not for models with OEM compression releases.
  • Includes a 4-gear set; due to gear drive character, some valve train noise may be present.
  • Installer must check coil bind, valve-to-valve clearance and valve-to-piston clearance before final assembly.

🇺🇸 Made in the USA. Follow the included instructions for safe installation and optimal performance.
