106-5235 Easy Start chain drive 640 camshaft set (CD)

For high-output builds, the S&S Easy Start 640 chain drive camshaft kit is the professional choice. This kit fits 2007 to 2017 Softail, 2006 to 2017 Dyna, and 2007 to 2016 Touring models. It is designed for 95-inch and larger engines with compression ratios from 10.5:1 to 11.5:1, and is the same grind found in S&S 124-inch crate engines. The Easy Start technology incorporates a centrifugal compression release, making it possible to start these high-compression monsters with a stock starter motor. This kit is sold as a set and includes the cams, bearings, and gasket. Because of the .640" lift, high-lift valve springs and clearancing are required. These cams are not suitable for kickstart models and require an idle adjustment to 1000-1100 RPM.
