Upgrade your engine's performance with the S&S Cycle 585G Gear Drive Camshaft Kit. Designed for optimal power and reliability, this kit replaces your stock chain-drive system with a precision gear drive, enhancing valve timing accuracy and enabling higher cam lifts.

Description

The S&S 585G gear drive camshaft kit is engineered for 88/96/103/110 cubic-inch engines with compression ratios between 10.0:1 and 10.5:1. By reversing the rear cam's rotation, the kit increases clearance between cam lobes, allowing for more aggressive cam profiles. This gear drive system eliminates chain lash, significantly boosting valve timing accuracy for improved engine performance. Recommended RPM range is 3500-6000 for 88" to 103" engines, and 2500-5500 for larger engines. Experience enhanced power and responsiveness with this premium camshaft kit. Made in the USA.
