S&S Cycle 551G Gear Drive Twin Cam Camshaft Kit 106-4868, Dyna

Camshaft Kit - 551G Gear Drive - Twin Cam | Dyna

The S&S Cycle 551G Gear Drive Twin Cam Camshaft Kit, manufacturer part number 106-4868, is designed for engines with 96 to 106 cubic inches of displacement and compression ratios from 9:1 to 9:9. This bolt-in cam set is intended for stock or mildly modified touring bikes and provides increased power across the RPM range, with improved low- and midrange torque and strongest performance from 1,000 to 4,000 RPM.

The kit reverses the rear cam’s direction of rotation, providing additional operating clearance between cam lobes and allowing higher cam lifts. Gear drive also increases valve timing accuracy by eliminating timing chain lash and the loose fit of the stock chain. Installation requires material removal from the inner surface of the stock gear cover, along with a hydraulic press and other professional-level tools. Cam bearings and gaskets must be replaced during installation, and S&S recommends using an adjustable pushrod and cover kit.

Included components are inner gears, outer gears, inner and outer bearings, gaskets and instructions. The installer must check coil bind, valve-to-valve clearance and valve-to-piston clearance. This kit is not recommended for compression ratios of 10:1 or greater. Due to the inherent characteristics of gear drives, increased valvetrain noise may occur. Made in the USA. Fitment includes the listed Harley-Davidson Dyna, Electra Glide, Street Glide, Ultra Limited and Road King applications.
