S&S Cycle 551C Series Grind Chain-drive Cam Kit for 07-17 Twin Cam & 06 FXD

Description

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
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.
Designed as bolt-in cam for touring bikes with compression ratio between 9:1 and 9:9
More power across the rpm range, with improved low and midrange torque
Can be used with stock pushrods, springs and lifters
Strongest from 1,000-4,000 rpm
Made in the U.S.A.
