Replacing your OEM Crank Pulley with the JHM Lightweight Crank Pulley will help you shave over 2 pounds 11 ounces of rotating mass off of your engine's rotating assembly.

Reducing the mass of parts included in the engine's rotating assembly (rods, pistons, crank, crank pulley, clutch, flywheel) will help you free up horsepower. This will lead to improvements in throttle responsiveness and overall power.
