This March Performance crankshaft pulley is CNC-machined from 6061-T6 billet aluminum, giving a true-running, durable replacement for the factory piece. It drives the whole accessory system from the crank, and its precise machining keeps the belt aligned with the rest of the drive. The finish is built to hold up to engine heat and keep the front of the engine looking sharp.
