S&S Cycle MR103 Gear Drive Camshaft Kit with Inner Gears Only

Bolt-in cam for 103in. Twin Cam motors. Use with stock heads and low restriction intake and exhaust. Broad torque curve improves output over stock over the entire rpm range. Camshaft gear drive kits increase valve timing accuracy by eliminating timing chain lash and loosely-fit stock chain drive. Reverses the rear cams 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 #0928-0017 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. Made in the USa. 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.
