Overview of S&S Cycle 510G Gear Drive Camshaft Kit - 33-5177
- Gear drive camshaft kits increase valve timing accuracy in Twin Cam engines 99-06 (except 06 Dyna models) by eliminating timing chain lash and loosely-fit stock cam gears
- Kits reverse the rear cam's direction of rotation and provide additional operating clearance between cam lobes; the result is that higher cam lifts are possible with the gear drive kit
- Kits include cams, inner gears, inner and outer bearings, outer drive gears, gasket and instructions
- Cams without any gears are also available - 14-8888
- To install S&S gear drive cams, material must be removed from the inner surface of the stock gear cover
- Cam bearings and gaskets must be replaced when installing new cams
- Also, a hydraulic press and other professional-level tools are required to install these kits
- S&S recommends that adjustable pushrod/cover kit 14-9988 be used
- Made in the U.S.A.
- For Cams only order 14-8888
- Kits require the use of adjustable pushrods and high-performance valve springs.
- 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.
