S&S Cycle 2006 Dyna Easy Start 635GE Gear Drive Camshaft Kit

If you're looking to give your 2006 Dyna or any 2007-up big twin engine a noticeable boost in performance, this S&S Cycle 635GE Gear Drive Camshaft Kit is a solid option. This kit is designed to increase your engine's power output while also making it easier to start, which is a big plus for any rider. It's a well-built upgrade that can make a real difference in how your bike feels on the road.

What makes this kit stand out is its gear drive design. Unlike chain-driven cams, gear drives offer a more direct connection between the camshaft and the crankshaft. This means less slop and more precise timing, which translates to improved throttle response and a stronger powerband. The 635GE camshaft profile is specifically chosen for its ability to deliver improved performance without making the engine difficult to start or requiring extensive modifications. You can even reuse many of your stock components, which simplifies the installation process and helps keep costs down.

When you open the box, you'll find everything you need to get this kit installed. It includes the cams themselves, a complete installation kit with bearings and a retaining ring, a new gearcover gasket, an O-ring, and thread lock. The detailed instructions will guide you through the process. While this kit is not CARB approved and cannot be shipped to California, it's a popular choice for riders looking for a significant performance upgrade for their Harley-Davidson big twin.
