S&S CYCLE Camshaft Kit - 585C - Chain Drive - Twin Cam

The cam is designed for 88 to 95 inch engines with compression ratios from 10 to 10.5:1 and 100 and 107 inch engines at 9.7:1 to 10.5:1 compression. Many riders are leery of the stock chain cam drive in late model big twins. Mt 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. The new with hydraulic chain tensioners works well for all but the most demanding high performance applications. That's why S&S offers our most popular grinds for 2007-16 big twins in a version. One advantage to a cam set is the expense. When you replace the stock cams with an S&S cam set, you re-use the stock cam drive components so you save money on parts.
