S&S CYCLE 551 Easy Start Camshaft Kit — 551 Series grind, chain – 99-06 Touring, 00-06 CVO, 00-06 Softail, 99-05 Dyna

551 Easy Start Camshaft Kit — Designed to reduce crank compression during startup to make the engine easier to crank; once the engine starts and rpm rise the compression-release lobe retracts and the engine runs with full compression and no loss of performance. ⚙️

• Optimized for 88"/96"/103" to 106" Touring bikes with slip-on mufflers and 9.0:1 to 9.0:9 compression.
• Bolt-in for stock or mildly modified Touring models.
• Greatly improves low-end and midrange torque; strongest from idle to 4000 rpm.
• Includes camshafts, gearcover gasket, bearings, retaining ring, o-ring, thread lock and instructions.
• Made in the USA. Not recommended for compression ratios of 10.0:1 or greater.
• Installer must check coil bind, valve-to-valve clearance and valve-to-piston clearance. Not for models with OEM compression releases.
• Can be used with stock pushrods, lifters, and springs unless noted.

For best results have this kit installed by a qualified technician and verify clearances during installation.
