330-0466 Easy Start gear drive MR103 camshaft kit (IOG)

This S&S Easy Start gear drive MR103 camshaft kit provides both a performance boost and a reliability upgrade for 1999 to 2006 Twin Cam engines, excluding 2006 Dyna models. With a .585-inch lift, these cams deliver strong power across the 2500 to 5500 RPM range, making them ideal for 103-inch builds. The gear drive design replaces the stock chain system for superior timing accuracy and durability. Thanks to the Easy Start compression release, your engine will fire up easily without needing a high-torque starter. This complete kit includes inner and outer gears, installation hardware, bearings, and gaskets. Note that high-lift valve springs and clearancing are required, and they are not compatible with kickstart models.
