106-5243 Easy Start gear drive 570 camshaft kit (IOG)

Designed for 88-inch to 103-inch engines with a 9:1 to 10:1 compression ratio, this S&S 570 Easy Start gear drive kit provides a significant power increase across the 3200 to 5700 RPM range. This complete kit fits 1999 to 2006 Twin Cam models, excluding the 2006 Dyna, and includes inner and outer drive gears along with all necessary installation hardware. The integrated Easy Start technology uses a centrifugal compression release to ensure your bike starts effortlessly using the stock battery and starter motor. Once running, the cams function normally with no loss in performance. Please note that these are not for kickstart models and will require high-lift valve springs and potential clearancing for proper fitment.
