What is the main advantage of using gear drive cams over stock chain drive?

Gear drive cams eliminate the cam chain, which can stretch, wear out, or cause tensioner issues over time. This results in a more reliable system with no worries about cam chain failure. It also provides more precise cam timing.

What specific components are included in this cam chest kit?

This kit includes a new oil pump (upgraded 2007-2016 style), a new cam support plate, new S&S gear drive camshafts, and new tappets. It's a complete package for overhauling the cam chest area.

Does this kit include everything needed for installation?

While this kit contains all the critical internal cam chest components, it's always recommended to consult the manufacturer's installation instructions. You may need additional items like gaskets, seals, or specific tools depending on the exact condition of your engine.
