Camshaft Kit - Easy Start - 551 Chain Drive - Big Twin '99-'06
The S&S Cycle Easy Start Camshaft Kit is designed for 1999-2006 Big Twin Touring models and provides easier starting without sacrificing normal engine performance. Its compression-release lobe temporarily reduces cranking compression during startup, then retracts centrifugally as engine speed increases. Once running, the engine operates with full compression for dependable performance. This bolt-in camshaft kit is optimized for 88- to 106-cubic-inch Touring engines equipped with slip-on mufflers, a stock starter, and compression ratios from 9.0:1 up to 9.9:1.
The 551 camshaft profile is tuned to deliver strong low-end and midrange torque, with its strongest performance from idle through 4,000 rpm. It is suitable for stock or mildly modified Touring applications and can be used with stock pushrods, lifters, and valve springs unless otherwise specified. The kit includes camshafts, a gearcover gasket, bearings, retaining ring, O-ring, thread-locking compound, and installation instructions for a complete installation solution.
Made in the USA, the S&S Cycle 106-5293 camshaft kit is not recommended for engines with compression ratios of 10.0:1 or higher or for models equipped with OEM compression releases. Before installation, the installer must verify coil bind, valve-to-valve clearance, and valve-to-piston clearance to ensure proper engine operation. This kit is intended for riders seeking improved starting performance and stronger usable torque while retaining the practical characteristics of a bolt-in camshaft upgrade.
