Camshaft - Easy Start - 635 H.O. Gear Drive - Twin Cam '07-'17 | Dyna '06

The S&S CYCLE 330-0339 Easy Start Camshaft is engineered to provide a seamless engine start-up experience while delivering optimal performance across a wide RPM range. This high-lift camshaft features a unique compression release mechanism that reduces initial crank compression, facilitating easier starting. Once the engine reaches higher RPMs, the centrifugal retraction of the compression release lobe allows the engine to operate normally with full compression, ensuring no loss of power or efficiency. Designed for modified engines with 106 cubic inches or larger displacement and compression ratios between 10.0:1 and 11.0:1, this camshaft is ideal for riders seeking enhanced performance.

Built with precision, the kit includes camshafts, a 4-gear set, gearcover gasket, bearings, retaining ring, O-ring, threat lock, and detailed instructions. Made in the USA, this camshaft is not a bolt-in component and requires additional modifications such as high-lift valve springs, adjustable pushrods, and clearance checks for optimal operation. It works best with stock, un-ported heads, though S&S CNC ported heads are recommended for maximum gains. Due to gear drive characteristics, users should anticipate increased valve train noise, which is typical of high-performance gear-driven systems.

This camshaft is designed to deliver peak power between 3,000 and 6,000 RPM, making it suitable for aggressive riding styles and performance-focused builds. While it is compatible with Twin Cam models from 2007 to 2017 and Dyna models from 2006, it is not suitable for models equipped with OEM compression releases. Overall, the S&S CYCLE Easy Start Camshaft offers a compelling combination of ease of starting, high performance, and reliable construction for motorcycle enthusiasts seeking to enhance their engine's capabilities.
