Interchangeable Crank Pulley Kit

2003-2004 Ford Mustang Cobra

Interchangeable Crank Pulley Kit (Includes One Pulley Ring)

This comprehensive kit allows the user to replace the heavy factory crankshaft pulley and cage assembly with a lightweight, precision-machined aluminum hub and interchangeable outer ring.  The kit includes all of the necessary hardware, including a billet bracket to cleanly and securely relocate the factory crank idler pulley.  Once this kit is installed, the user can adjust the vehicle's boost level by simply changing the outer pulley ring to any of the available Metco pulley rings, a process that takes just minutes.

This kit is custom-engineered to be a complete bolt-on, with no cutting, drilling, or irreversible changes required.  A special tool is included to assist the installer with removal of the factory pulley retaining bolt.  In most cases, total time required for installation is about two hours.  

Pulley ring choices include:  1" smaller than stock diameter (for use with aftermarket superchargers using pump fuel), stock diameter, +2 lbs, +4 lbs, +6 lbs, +8 lbs, and +10 lbs.  Please make your selection below. 

Please note that Metco offers underdrive alternator pulleys that are recommended for use with +2 lb, +4 lb, +6 lb, and +8 lb, (and larger) crank pulley rings.  These alternator pulleys are also listed in the Mustang Cobra section of our site.  

Note 1:  Metco Motorsports crankshaft pulley rings as included in this kit are also available separately.

Note 2:  A special crank pulley hub is available for applications using the ATI harmonic balancer for the Cobra (PN 918036).  This custom crank pulley hub is listed elsewhere in this section, and can be substituted for the standard crank hub included in this kit at no extra charge.  This custom crank pulley hub is only available for purchase directly from Metco Motorsports.    

Beware of unauthorized knockoffs offered by LFP.  These parts are not the same as those offered by Metco Motorsports, and Metco Motorsports has no affiliation with LFP whatsoever.
