EV1010-1181 Industries, ''EasyStart'' jackshaft assembly

The EasyStart jackshaft assembly from Evolution Industries is a specialized conversion kit designed for high-performance starting systems. This version features a 10-tooth pinion gear and is intended exclusively for use with the Evolution Industries 84-tooth EasyStart starter ring gear conversion. It fits 1994 to 2006 Big Twin models, excluding the 2006 Dyna. The kit is fully inclusive, providing the jackshaft bolt, spring, pinion gear, thrust washer, lock plate, and all required couplings. By using this specific gear ratio, you get a more efficient cranking cycle, which is vital for high-displacement or high-compression engines that struggle with standard starter setups.
