    S&S Cycle 509G Grind Gear Drive Cam Gears Kit .509 Lift Harley Twin Cam 99-06 Zoom


    • 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 # 93-5095 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 U.S.A.


    • Lower lift allows them to be bolted into stock 96"-106" 06 engines with stock valve springs
    • Bolt-in cams for 88 CID engines with stock compression ration
    • Strongest from 1,000-4,500 rpm
