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
High-power cam for modified engines, increase compression, high-lift springs and large bore throttle body required
For best results requires ported heads, low restriction intake/exhaust
Strongest from 4,000-6,500 rpm
Made in the U.S.A.
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
