This is a billet 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 a Dennis Carpenter Super Stock Camshaft, 1 1/2" valve and a Mikuni Carburetor, we can develop as much as 14 horsepower from a standard 8 horse engine.
