HP103 Cam Kit

Features

• 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 #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 U.S.A.
• Cams for 00-06 Twin Cam are for use with stock splined drive gears; for installation on 99 Twin Cam motors you must purchase splined outer drive sprocket; S&S recommends that Andrews 4340 steel drive sprocket PART #DS-199175 be used
• Cams for 06 Dyna and 07-16 Twin Cam are for use with models with hydraulic tensioner chain-drive system; require high-lift valve springs
• Made in the U.S.A.
• GEAR DRIVE CAM KITS
• 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.
