This is a billit steel crank as opposed to the original Cushman cast cranks. This has a 3/16 longer stroke than the standard Cushman crank. This noticeably increases the displacement in the engine increasing your torque and horsepower. Combined with our Cam Shafts, an 1 1/2" valve, and a Mikuni Carburetor we can develop as much as 14 horsepower from a standard 8 horse engine.
