S&S Cycle HP103 Chain Drive Camshaft Kit for Twin Cam '07-'17 and Dyna '06 – Easy Start Design

Camshaft Kit - Easy Start - HP103 Chain Drive - Twin Cam '07-'17 | Dyna '06

The S&S Cycle HP103 Chain Drive Camshaft Kit (Part Number: 330-0346) is engineered to deliver high-performance gains for Twin Cam models from 2007 to 2017 and Dyna models from 2006. This kit features a specialized camshaft design that allows for easy engine start by initially reducing crank compression. Once the engine reaches higher RPMs, the centrifugal retraction of the compression release lobe restores full compression, ensuring consistent power output without sacrificing performance or efficiency. This makes it ideal for riders seeking improved high RPM power, particularly in the 3000 to 6000 RPM range. The kit includes all necessary components such as camshafts, gear cover gasket, bearings, retaining ring, O-ring, thread lock, and installation instructions, providing a comprehensive upgrade solution. Crafted in the USA, these bolt-in cams are compatible with stock 9.7:1 compression ratio engines, up to 10.5:1, and work well with unported stock heads or S&S CNC ported heads for enhanced airflow and performance. It is important for installers to verify coil bind, valve-to-valve, and valve-to-piston clearances prior to installation to ensure optimal operation. Not suitable for models equipped with OEM compression releases, this camshaft kit offers a straightforward upgrade for riders looking to boost high RPM power with minimal hassle.
