S&S CYCLE Easy Start Camshaft for Twin Cam '07-'17 and Dyna '06 Models - Part 330-0057
Regular price $1,070.95 USD
Category:
Camshaft - Easy Start - 557 Gear Drive - Twin Cam '07-'17 | Dyna '06
The S&S CYCLE Easy Start Camshaft (Part 330-0057) is designed to facilitate effortless engine startups on Twin Cam models from 2007 to 2017 and Dyna models from 2006. This camshaft features an innovative compression release system that temporarily reduces crank compression during startup, making engine ignition smoother and less strenuous on the starter. Once the engine reaches a certain RPM, the centrifugal mechanism retracts the compression release lobe, restoring full compression for optimal performance without any compromise in power or efficiency. This thoughtful design is ideal for heavy bikes like Tri-Glides and other similar applications, providing reliable starting performance under demanding conditions. Crafted with a bolt-in design, the camshaft includes essential components such as camshafts, gearcover gasket, bearings, retaining ring, O-ring, threat lock, and detailed installation instructions, ensuring a straightforward installation process. Made in the USA, this camshaft is built to high standards of quality and durability. Installation requires the mechanic to verify coil bind, valve-to-valve clearance, and valve-to-piston clearance to ensure proper operation. Not compatible with models equipped with OEM compression releases, this camshaft offers an excellent upgrade for riders seeking improved starting ease and consistent performance in heavy-duty motorcycle applications.

- Designed for Twin Cam '07-'17 and Dyna '06 motorcycle models
- Compression release feature assists with easy engine startup
- Centrifugally retracts compression lobe at higher RPMs for full compression
