106-5242 Easy Start gear drive 570 camshaft set (IG)

This S&S 570 Easy Start gear drive cam set is designed for 1999 to 2006 Twin Cam models, excluding the 2006 Dyna, and is optimized for 88 to 103-inch engines with 9:1 to 10:1 compression. This set includes the camshafts with inner gears only and provides a solid power increase from 3200 to 5700 RPM. The Easy Start technology makes starting your Big Twin effortless by reducing cranking pressure, allowing you to stick with your stock starter and battery. Note that this is not a complete kit; the required installation hardware is available separately under part number 503566. These cams are not bolt-in for these years and will require high-lift valve springs and clearancing.
