S&S Cycle 99-06 BT Easy Start Gear Drive Camshaft Kit

If you're looking to get more out of a modified Harley-Davidson Big Twin engine, the S&S Cycle 635GE Easy Start gear drive camshaft kit is a solid option. This kit is specifically designed for engines that have been upgraded with larger displacement and higher compression, offering a significant boost in torque and horsepower beyond what typical bolt-in cams can achieve. It's a well-built component that can make a real difference in how your bike performs when you twist the throttle.

The gear drive design means you won't have to worry about chain stretch or tensioner wear over time, providing a more consistent and reliable camshaft timing. This kit is recommended for modified engines, and to get the most out of it, you'll want to pair it with high-lift springs, as they are required for all applications. For optimal performance and longevity, especially with chain drive cams, S&S Cycle also highly recommends upgrading to an S&S oil pump and cam support plate, along with a stock 2007 and later style hydraulic cam chain tensioner.

This kit fits a wide range of Harley-Davidson Big Twin models from 1999 through 2006, including popular bikes like the Road King, Electra Glide, and Dyna Super Glide. While this kit is designed for performance, it's important to note that it is not CARB approved and cannot be shipped to California. For maximum performance gains, consider pairing this camshaft with performance intake and exhaust components.
