310-0812 Complete cam chest kit with gear drive 551GE cams

Upgrade your 1999 to 2006 Twin Cam (except 2006 Dyna) with this S&S gear drive cam chest kit, featuring 551GE Easy Start cams. This set is designed to provide better low-end torque while making the bike much easier to crank over, thanks to the centrifugal compression release. The gear drive system provides optimized cam timing and removes the worry of plastic tensioner failure. Included in this comprehensive kit are a high-volume oil pump, an upgraded cam support plate, performance tappets, and adjustable chromoly pushrods. This setup not only improves reliability but also upgrades the oiling system of early Twin Cams to the more efficient 2007 to 2017 style, ensuring consistent oil pressure across all riding conditions.
