2009-2015 CTS-V, 2012-2015 Camaro ZL1
This heavy-duty pulley is designed to replace the original tensioner pulley on the supercharger drive of the LSA engine. This pulley is precision-machined from high-grade billet aluminum and fitted with dual bearings for unmatched durability. This pulley includes a billet front cover for the bearings as well as an application-specific stainless steel pulley bolt. The face of the pulley has a machined finish that matches our supercharger idler pulley (PN MIP-100V, listed in this section), and the back side and belt surface of the pulley are hard-coat anodized in black.
This pulley installs as direct replacement for the original. It is the same diameter (76mm/3.0") as the original pulley so the existing belt can be re-used.
This tensioner pulley is a specialty item, and may require 3-4 weeks from the date of order to ship.
