S&S Cycle 2007+ BT 625C Chain Drive Camshaft Kit

If you're looking to get more performance out of your Harley-Davidson Big Twin engine, especially those 95 cubic inch or larger with a 10.0 to 10.75:1 compression ratio, this S&S Cycle 625C Chain Drive Camshaft Kit is a solid option. Many riders are wary of the stock chain cam drive, but the version used in 2006 and later models was a significant improvement over earlier designs, working well for most high-performance needs. This kit lets you swap in S&S's popular 625C cam grinds while reusing your stock chain drive components, which helps save on parts costs.

The 625C cam offers a valve lift of 0.625 inches on both intake and exhaust, with a duration at 0.053 of 255 degrees for the intake and 260 degrees for the exhaust. This setup is designed to work with engines that have a specific compression ratio range. The kit comes with the cams themselves, a gear cover gasket, cam bearings, and instructions. Keep in mind that you will need to source special valve springs separately to complete the installation.

This camshaft kit fits a wide range of Harley-Davidson models, including many from the Dyna, Softail, and Touring families from 2006 and 2007 onwards. It's a well-built component from S&S Cycle, a well-known name in performance Harley parts, offering an improved performance profile for your engine.
