S&S Cycle® Raw Gear Drive 551 Cam Kit, with All Necessary Hardware - Made in U.S.A.

Fits 2007-2017 Harley-Davidson Models with Twin Cam Motors; 2006 Dyna Models

Features:

• GEAR DRIVE CAM KITS FOR TWIN CAM

• 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.

• NOTE: Kits require high-performance valve springs (except 509G and 510G) when installed in 99-04 models.

• NOTE: Installer must check coil bind, valve-to-valve clearance and valve-to-piston clearance.

• NOTE: Due to the inherent characteristics of gear drives, you may experience more valve train noise.

• CHAIN DRIVE CAM KITS FOR TWIN CAM

• 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 07-17 Twin Cam are for use with models with hydraulic tensioner chain drive system; cams 510C and 551C are bolt-in applications, all others require high-lift valve springs

• Made in the U.S.A.

• NOTE: Installer must check coil bind, valve-to-valve clearance and valve-to-piston clearance.

• HP103 SERIES GRIND CAMS

• 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
