2003-2004 Ford Mustang Cobra
Interchangeable Crank Pulley Kit (Includes Two Pulley Rings)
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 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.
This kit is identical to the Metco Motorsports ICPCOBRA1 except that this kit
allows the user to select two pulley rings instead of one.
Pulley ring choices include: 1" smaller than stock diameter (for use with
Kenne-Bell or Whipple superchargers), stock diameter, +2 lbs, +4 lbs, +6 lbs,
+8 lbs, and +10 lbs. Please make your selections below.
Please note that Metco offers underdrive alternator pulleys that are recommended
for use with +4 lb, +6 lb, +8 lb, and +10 lb crank pulley rings. These alternator
pulleys are 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). If your car is equipped with
this balancer, please contact us for availability and pricing.
