S&S Cycle 509G Camshaft Kit - 330-0017

Upgrade your Harley-Davidson's performance with the S&S Cycle 509G Gear Drive Camshaft Kit. This kit is designed to provide increased valve timing accuracy and improved engine performance, making it an excellent choice for enthusiasts and professionals alike. Experience enhanced power and responsiveness across a broad RPM range.

Description

The S&S Cycle 509G Gear Drive Camshaft Kit is engineered to boost the performance of 88 CID engines with stock compression ratios. By replacing the stock chain drive with a gear drive, the kit significantly increases valve timing accuracy by eliminating timing chain lash. The reversed rear cam rotation provides additional operating clearance between cam lobes, allowing for higher cam lifts. Designed for strong performance from 1000-4500 rpm, this kit provides a noticeable improvement in power and throttle response. With 180 psi cranking compression (12.41 Bar in EU), compression releases are not required. These cams can also be bolted into 96"-106" '06 engines with stock valve springs, due to the lower lift.
