This custom adapter is part of the Metco Motorsports fuel rail adapter kit (PN MFRS2000) used with Metco fuel rails.  This is the billet fitting that mates the high-pressure hose of the MFRS2000 to the factory fuel feed line.

This adapter is CNC-machined from 6061 aluminum and has a barbed end on one side for the high-pressure hose of your choice, and the opposite end is configured to mate with the original fuel feed line.

We offer this adapter separately from the MFRS2000 assembly for users wishing to design a custom fuel system for their vehicle.

Our crank pulley rings are designed for use with our Metco Motorsports Interchangeable Crank Pulley Kit offered for the supercharged Lightning and Harley Davidson  truck and the supercharged Mustang Cobra.

These crank pulley rings are precision-machined from billet aluminum and then black-anodized for good looks and long-lasting surface protection.

If you already have the Interchangeable Crank Pulley Kit on your vehicle, one of these crank pulley rings is all that is needed to change your boost level.

Our crank pulley rings are available in several sizes, including an underdrive pulley for use with a Kenne-Bell or Whipple supercharger, a stock-diameter ring, +2 lb, +4 lb, +6 lb, +8 lb, and +10 lbs.  Please make your selection above.

Note:  Some pulley rings may be available in a machined finish.  Please call or email for availability.

Replace the original 2.7" supercharger pulley on your 2013 or newer GT500 and gain 2-3 lbs of additional boost.

Our one-piece pulley is precision-machined from high-grade steel and then black-powdercoated for a stealthy appearance.  The pulley bore is machined to exact specifications for a proper press-fit installation.

If this pulley is paired with our MSI-90 auxiliary idler kit the original supercharger belt can be retained and there will be no belt slip.

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 ICPCOBRA2 except that this kit allows the user to select one pulley ring instead of two.

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 selection above. 

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 "Alternator Pulley" in the 03-04 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 pricing and availability.

Stock-size and 1" smaller than stock size pulley rings are also available for use with Kenne-Bell or Whipple superchargers. Learn More

Replace the original 3.00" supercharger pulley with one of our precision-made supercharger pulley kits to add boost to your Shelby Mustang.  The kit includes a pulley hub machined from high-grade steel that presses onto the blower shaft.  The CNC-machined aluminum ring bolts to the steel hub using the supplied stainless steel fasteners, and this two-piece design makes subsequent pulley ring changes a snap.

The steel hub is re-usable (unlike aluminum one-piece blower pulleys), and is nickel-plated for long lasting surface protection.  The aluminum ring is hard-coat anodized in black to resist surface wear.

We recommend the use of our Auxiliary Idler Kit (Metco Motorsports PN MSI-90) with this supercharger pulley.  When these two components are installed together, the vehicle's original serpentine belt can be re-used.

Note 1:  Due to the extremely tight interference fit of the factory supercharger pulley on the Shelby GT500 and the weak design of the pulley itself, the factory pulley is often damaged upon removal.  To change pulleys, the use of a hydraulic press is recommended but a high-quality pulley removal and installation tool can also be used.  We manufacture our own pulley tool and it is available under Metco Motorsports PN MPT0001, listed elsewhere in this section. 

The steel pulley hub is nickel-plated and is no longer offered in the black oxide finish shown in some of the images above.

If your 2007-2012 GT500 is equipped with our popular 2.60" supercharger pulley upgrade, you may add this stock-appearing pulley cover for a stealthy look.  This cover is precision-machined from billet aluminum and then black-anodized, and it simply slides over the 2.60" pulley.  The cover is secured using a stainless steel socket-head fastener (provided) that threads into the hole at the end of the supercharger shaft. .

*Please note that this pulley cover is only compatible with Metco Motorsports 2.60" supercharger pulleys manufactured after Novermber 2012.  If you have doubts about compatibility with your pulley, measure your pulley ring and its widest point (just forward of the belt surface) to confirm an OD of 69.5mm.  If your pulley measures 72mm, it is the earlier design and this cover will not fit.

These pulley rings are designed for use with Metco Motorsports two-piece supercharger pulleys.  If you already have a Metco supercharger pulley on your GT500, one of these rings is all that is needed to change the boost level on your vehicle.  These pulley rings will bolt to your existing pulley hub using the same (5) fasteners, and no special tools are required for the change.

Our pulley rings are precision-machined from billet aluminum and then black anodized for long lasting surface protection. 

Listed below are approximate boost gains that can be expected when installing these pulleys on a Shelby GT500:

MSPR3.00: Stock diameter, no change  MSPR2.80:  +2-3 lbs  MSPR2.60:  +3-4.5 lbs

We recommend the use of our Auxiliary Idler Kit with the 2.60" supercharger pulley to maximize belt wrap and to minimize belt slippage.  Our idler kits are listed elsewhere in this section.  

Kit includes (1) pulley ring.  Please make your selection above.
