2003-2004 Mustang Cobra

Underdrive Alternator Pulley

Our underdrive alternator pulleys are CNC-machined from billet aluminum and black anodized for long-lasting surface protection.  The pulleys are sized to maintain proper alternator speed when used on 2003 and 2004 Mustang Cobras equipped with the Metco Motorsports Interchangeable Crank Pulley Kit.  

These alternator pulleys install as a direct replacements for the factory alternator pulley and require no modifications or special tools.  A longer belt will be required.  

An underdrive alternator pulley is recommended when using our +4 lb and larger crank pulley rings.  Each boost level requires a specific alternator pulley.  Please make your selection below.

Note 1:  As of 1/2012, all Metco Motorsports alternator pulleys are machined to include the separate spacer shown in the above image.  A separate spacer is no longer offered.

These alternator pulleys do not fit the Mechman alternator.  These pulleys are intended for the 6G alternator used in select Modular Ford applications.
