Double-Bearing Idler Pulley 50mm

2009 & Newer Cadillac CTS-V, 2012 & Newer Camaro ZL1

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.

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.  Special high-speed bearings (not shown) that have been proven to survive at the high speeds that a small-diameter pulley will see are fitted in a dual-bearing configuration to provide unmatched stability and durability.  A precision-machined billet sleeve is included to provide the perfect fit over the factory pulley mount.

This replacement idler pulley is necessary in CTS-V & ZL1 applications using our larger supercharger drive rings (sizes 9.1″ and up).

This pulley is offered in two configurations:  a 1.5″ width for the GM LSA application and a 1.75″ width for custom applications using a 10-rib belt.
