Description
Chain Drive Camshaft Kit for '06 Dyna® and 2007-'16 Big Twins
- 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 #14-9988 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
- 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
