Camshaft Kit - 551C Chain Drive - Twin Cam | Dyna
Upgrade the performance of compatible Harley-Davidson Twin Cam and Dyna motorcycles with the S&S Cycle 551C Chain Drive Camshaft Kit, part number 106-4858. Designed for engines ranging from 96 to 106 cubic inches with compression ratios from 9:1 to 9.9:1, this bolt-in cam set is well suited for stock or mildly modified touring bikes. Its performance profile is engineered to provide stronger power throughout the usable rpm range while maintaining practical street manners.
The S&S Cycle 551C camshaft kit is especially effective in the low- and midrange, with its strongest performance characteristics from 1,000 to 4,000 rpm. This makes it a practical choice for riders seeking improved throttle response, enhanced acceleration, and increased torque during everyday riding, touring, and passing situations. The cam set is intended to complement engines that benefit from additional usable power without requiring extensive modifications.
For 2006 Dyna models and 2007 through 2017 Twin Cam applications, these cams are designed for motorcycles equipped with a hydraulic tensioner chain drive system. The kit is made in the USA and should be installed by a qualified technician. Before final assembly, the installer must verify coil bind, valve-to-valve clearance, and valve-to-piston clearance to confirm proper compatibility and safe operation. The cams are not recommended for engines using compression ratios of 10:1 or greater. Confirm application details and engine specifications before installation.
