330-0445 Easy Start chain drive HP103 camshaft set (CD)

Sold as a kit, this S&S Easy Start chain drive HP103 camshaft set is designed specifically for 103-inch Twin Cam engines from 1999 to 2006, excluding the 2006 Dyna. These cams feature a .575-inch lift and are optimized for engines with compression ratios between 9.7:1 and 10.5:1, delivering their best power in the 3000 to 6000 RPM range. The Easy Start system makes starting your high-compression motor a breeze by reducing cylinder pressure during cranking, so you won't need a heavy-duty starter. This kit includes the necessary gaskets and bearings for the install. Be aware that these require high-lift valve springs and clearancing, and they are not compatible with kickstart models or S&S 79cc heads.
