HP103 Easy Start Camshaft Kit

🔧 Designed to reduce crank compression during initial starting, this kit lets the engine start more easily and then returns to full compression as rpm increases. The compression release lobe is centrifugally retracted once the engine is running, so there is no loss in performance at operating speed.

  • Bolt-in cams for 103" engines, compatible with stock compression ratios from 9.7:1 up to 10.5:1.
  • Provides power in the high rpm range (3000–6000 rpm).
  • Kit includes camshafts, gearcover gasket, bearings, retaining ring, o-ring, thread lock and instructions.
  • Made in the USA.
  • Works well with stock unported heads and also with S&S CNC ported heads.

Installer must check coil bind, valve-to-valve clearance and valve-to-piston clearance. Not for models with OEM compression releases.
