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

Cam bearings and gaskets must be replaced when installing new cams

Kits require high-performance valve springs when installed in 99-04 models.

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