4-Piece Billet Idler Kit

4-Piece Billet Idler Kit

2005 - 2010 Mustang GT

Six-Rib Accessory Drive

An Original Metco Motorsports Design!

The billet idler pulleys included in this kit can be installed as direct replacements for the original idler pulleys on the Ford 4.6L 3V engine.  These pulleys are precision-machined from billet aluminum and are built to exactly match the dimensions of the OEM pulleys. 

Like all Metco Motorsports pulleys, these heavy-duty pulleys are hard-coat anodized in black on the back side and belt surface to resist wear from the belt and surface corrosion.  The front of the each pulley is machined to match the popular design of the pulleys we manufacture for the Cobra, Lightning, and GT500 applications.  Like our other pulleys, each pulley in this kit (except the tensioner pulley) includes a billet bearing cover and a stainless steel retaining bolt.

The kit includes (2) 90mm smooth idlers, (1) 87mm grooved idler pulley, and (1) 76mm smooth idler pulley.  No modifications to the vehicle are necessary and no special tools are required for installation.  The original serpentine belt can be re-used. 

All of the pulleys in this kit are available separately.  Please feel free to call or email if you have questions or need a custom kit configuration.

Important Note:  Due to the unique manufacturing requirements, this kit is not a regular catalog item for us and it is offered with very limited availability.  This kit can only be purchased directly from Metco Motorsports, and it is not available for purchase through any of our authorized retailers.   The lead time for this kit is generally 2-4 weeks from the date of the order.

Installation Notes:  One of the included 90mm smooth idler pulleys installs in place of the original pulley on the driver's side of the engine, and the grooved idler pulley replaces the original idler directly beneath it.  The second 90mm idler pulley replaces the original on the passenger side of the engine above the tensioner, and the included 76mm pulley replaces the pulley on the tensioner arm.  On the tensioner arm, an application-specific hex bolt is provided to mount the pulley in the same fashion as the original pulley.
