This billet idler pulley can be installed as a direct replacement for the unsightly plastic pulley mounted on the tensioner arm of the new Camaro SS and the supercharged CTS-V.

Like all Metco Motorsports pulleys, this pulley is precision-machined from billet aluminum and then hard-coat anodized in black on the back side of the pulley and on the belt surface.  Like our other pulleys, a billet bearing cover and stainless steel retaining bolt is included.

This 87mm 6-rib pulley is slightly smaller than the OEM pulley, but serves to optimize belt tension as indicated on the factory tensioner indicator.  This pulley represents a simple and inexpensive way to enhance the underhood appearance of your new Camaro or CTS-V and add durability at the same time.  No modifications are necessary to install this pulley and the original serpentine belt can be re-used.

Installation Note:  This pulley replaces the pulley on the tensioner arm, located on the passenger side of the engine next to the throttle body inlet.  On the supercharged CTS-V application, this pulley is part of the accessory drive, not the supercharger drive, and does not affect the boost level provided by the supercharger.
