S&S Cycle Camshaft Kit - 551G Gear Drive - Twin Cam

• 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.
