The S&S Cycle 330-0543 Complete Chain Drive Cam Chest Kit provides a comprehensive replacement and performance upgrade for 1999–2006 Harley-Davidson Big Twin engines. This kit replaces critical cam chest components, including the oil pump, cam support plate, camshafts, chain tensioners, and tappets, with premium U.S.-made S&S Cycle components. It is designed to eliminate uncertainty about the condition of these high-wear parts while improving engine performance and supporting reliable valve-train operation.
Upgrade 1999–2006 models to the 2007–2016 style oil pump included with the kit for better, more consistent oil pressure. S&S hydraulic cam chain tensioners help improve valve timing stability and extend chain life, while the included S&S Quickee pushrods simplify installation without requiring removal of the rocker covers. The Easy Start chain-drive performance cam set delivers higher lift and optimized cam timing for responsive performance gains.
This S&S Cycle cam chest kit fits select Harley-Davidson Big Twin applications, including FXDX Dyna Super Glide Sport, FXDXT Dyna Super Glide T-Sport, and FXSTDSE Screamin’ Eagle Softail Deuce models. Verify exact year, model, engine configuration, and camshaft requirements before installation. The kit is intended for competition or off-road use where applicable and is not California Air Resources Board approved.
