• Camshaft gear drive kits increase valve timing accuracy by eliminating timing chain lash and loosely fit stock chain drive
• Reverses the rear cam's direction of rotation, providing additional operating clearance between cam lobes; as a result, higher cam lifts are possible with the gear drive kit
• Kits include cams, inner gears, outer drive gears, inner and outer bearings, gasket and instructions
• Material must be removed from the inner surface of the stock gear cover to install S&S gear drive cams
• A hydraulic press and other professional-level tools are required to install these kits
• S&S recommends that adjustable pushrod/cover kit PART #14-9988 be used
• Cam bearings and gaskets must be replaced when installing new cams
• Cams are also available with inner gears only; intended for cam replacement for motors that have already been converted to an S&S gear-drive system
• Designed as bolt-in cam for touring bikes with compression ratio between 9:1 and 9:9
• More power across the rpm range, with improved low and midrange torque
• Can be used with stock pushrods, springs and lifters
• Strongest from 1,000-4,000 rpm
• Made in the U.S.A.

NOTE: Kits require high-performance valve springs (except 509G and 510G) when installed in 99-04 models

NOTE: Installer must check coil bind, valve-to-valve clearance and valve-to-piston clearance

NOTE: Due to the inherent characteristics of gear drives, you may experience more valve train noise
