CAMS HP103GD 99-06

HP103 Cam Kit

• 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.
• Due to the inherent characteristics of gear drives, you may experience more valve train noise.
• Installer must check coil bind, valve-to-valve clearance and valve-to-piston clearance.
• Bolt-in cam for 103” and 106” Big Bore Twin Cam motors
• Use with stock heads (up to 10.2 compression) and low restriction intake and exhaust
• Great for lighter bikes with strong power from 3500-6000 rpm
