The S&S Cycle Camshaft Kit part number 330-0445 is designed for easy engine startup by initially reducing crank compression. During engine operation, the centrifugal retraction of the compression release lobe allows the engine to run normally with full compression, ensuring no performance loss. This kit is ideal for engines with a displacement of 103 cubic inches and suitable for stock compression ratios up to 10.5:1, providing increased power in the high RPM range from 3000 to 6000 rpm. The kit includes high-quality camshafts, a gearcover gasket, bearings, a retaining ring, O-ring, thread lock, and detailed installation instructions. Made in the USA, these cams are bolt-in replacements that require the installer to check coil bind, valve-to-valve clearance, and valve-to-piston clearance to ensure proper fitment and performance. They work well with stock, unported heads but are also optimized for use with S&S CNC ported heads for enhanced airflow. Not suitable for models featuring OEM compression releases, this kit is a reliable upgrade for Twin Cam engines from 1999 to 2006, excluding the '06 Dyna model. With a weight of approximately 61.6 pounds, these components offer a straightforward installation process and improved high-RPM power delivery for Harley-Davidson enthusiasts seeking performance enhancements.
