S&s cycle cams chn dr 510c 07-15bt

Kit includes cams, gearcover gasket, cam bearings, and instructions. Fits 2006 Dyna® and 2007-Up big twin models. The 510 cam is designed as a bolt in cam for 88, 95, and 96 inch engines with compression ratios below 9.7:1, and is intended primarily for stock heads that have not been ported. Can be used with stock valve springs. 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.
