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

Fits 2006 HD® Dyna® and 2007-'16 big twin models. The 625 cam is designed for 95 inch or larger engines with compression ratios between 10.0 and 10.75:1.Many riders are leery of the stock chain cam drive in late model big twins. While it is true that the early version introduced in 1999 was often not well suited to high performance applications, the later version introduced in the 2006 Harley-Davidson® Dyna® model, and later incorporated in all big twins in the 2007 model year, was vastly improved. New chain drive with hydraulic chain tensioners work well for all but the most demanding high performance applications. That's why S&S now offers our most popular grinds for 2007-up big twins in a chain drive version. The advantage to a chain drive cam set is the expense. When you replace the stock cams with an S&S chain drive cam set, you re-use the stock cam drive components so you save money on parts.
