The S&S Cycle HP103 Chain Drive Camshaft Kit, part number 330-0442, is designed for Harley-Davidson Twin Cam engines with 103-cubic-inch displacement and stock compression ratios from 9.7:1 up to 10.5:1. This bolt-in camshaft kit delivers a strong, usable powerband for riders seeking improved performance without extensive engine modifications. It is intended for 1999-2006 Twin Cam applications, excluding 2006 Dyna models.
This camshaft kit is compatible with stock, un-ported cylinder heads and is also well suited for use with S&S Cycle CNC-ported heads. Its performance range is concentrated between 3,000 and 6,000 rpm, providing responsive acceleration and strong mid-to-upper-range power for street and performance-oriented riding. The chain-drive design supports a direct installation approach for compatible engine configurations.
The S&S Cycle HP103 camshaft kit is made in the USA and requires high-lift valve springs for proper operation. Before installation, carefully verify coil-bind clearance, valve-to-valve clearance, and valve-to-valve piston clearance. These checks are essential for confirming adequate component clearance and ensuring the camshaft is correctly matched to the engine, cylinder heads, pistons, and valve train components. Professional installation and setup are recommended for the best results.
