The 557 Easy Start Camshaft Kit reduces crank compression during startup to allow easier engine cranking, then the compression release lobe retracts as rpm rises so the engine runs with full compression and no loss of performance. 🔧

  • Designed for Tri-Glides and other heavy bikes.
  • Bolt-in design for straightforward installation.
  • Includes camshafts, gearcover gasket, bearings, retaining ring, o-ring, threat lock and instructions.
  • Made in the USA.

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