Metco: 63mm Idler Pulley [CTS V gen 2, Camaro ZL1 gen 5, LSA]



We offer this replacement idler pulley in a reduced diameter (2.00") to provide the necessary clearance for overdrive crank pulley rings.  This idler pulley installs as a direct replacement for the factory idler located at the 10 o'clock position relative to the crank pulley.  Our pulley even uses the original pulley bolt for installation.  This pulley is approximately 1.5" wide and is necessary in CTS-V & ZL1 LSA applications using larger lower crank pulley rings.

Like all Metco idler pulleys, this pulley is precision-machined from billet aluminum and hard-coat anodized on the backside and the belt surface for extreme wear resistance.  The pulley is fitted with dual bearings to provide unmatched stability and durability.  A precision-machined billet sleeve is included to provide the perfect fit over the factory pulley mount.
