The pulley is CNC-machined from billet aluminum and black anodized for long-lasting surface protection. The pulley is sized to maintain proper alternator speed when used on 2003 and 2004 Mustang Cobras equipped with the Metco Motorsports +6 lb crank pulley kit.
This pulley installs as a direct replacement for the factory alternator pulley and requires no modifications or special tools.
