Features
- Designed for engines with 96 to 106 CID and 9:1 to 9:9 compression, this is a bolt-in cam set for stock or mildly modified touring bikes
- Reverses the rear cam's direction of rotation, providing additional operating clearance between cam lobes making higher cam lifts possible
- More power across the rpm range, with improved low and midrange torque, strongest from 1,000-4,000 rpm
- Increases valve timing accuracy by eliminating timing chain lash and loosely fit stock chain
- Material must be removed from inner surface of the stock gear cover to install
- A hydraulic press and other professional level tools are required for installation
- Cam bearings and gaskets must be replaced when installing new cams
- S&S recommends that adjustable pushrod/cover kit be used
- Not recommended for compression ratios of 10:1 or greater
- Kit includes inner gears, outer gears, inner and outer bearings, gaskets and instructions
- Made in the USA
Notes
- Installer must check coil bind, valve to valve clearance, and valve to piston clearance.
- Due to the inherent characteristics of gear drives, you may experience more valve train noise.
- Not for '06 Dyna.
- Some models will require high-lift springs
