S&S CYCLE 583 Easy Start Camshaft Kit — 583 Series grind, S&S Cycle – 06-16 Dyna, 03, 07-16 Touring, 07-15 CVO, 10-16 Trike, 07-16 Softail

The 583 Easy Start Camshaft Kit simplifies starting by temporarily reducing crank compression during initial spin, then returning to full compression as rpm increases. ⚙️

• Allows for easy start by initially reducing crank compression, but once the engine starts and rpm increases, the compression release lobe is centrifugally retracted and the engine runs normally, with full compression, and without any loss in performance.
• Optimized for use as a great overall camshaft for Softail and Dyna, but can be used in any Big Twin.
• Provides strong low-end torque and horsepower; strongest from 1500 rpm to 5000 rpm in Softail and Dyna models.
• Bolt-in; includes camshafts, gearcover gasket, bearings, retaining ring, o-ring, thread lock and instructions.
• Made in the USA. 🔧

Installer must check coil bind, valve-to-valve clearance and valve-to-piston clearance. Not for models with OEM compression releases. Not recommended for compression ratios of 10.0:1 or greater.
