Idler Pulley Relocation Bracket
For LSA Applications, including 2009-2015 Cadillac CTS-V, 2012-2015 Camaro ZL1
This precision-machined idler relocation bracket is designed specifically for the GM LSA application. The bracket installs as a direct replacement for the original bracket, but moves the crank idler pulley (bottom pulley) up and away from the crank pulley to allow for drive rings sized 9.55" and larger. Another important benefit is that the supercharger idler pulley's position (top pulley) is relocated slightly to improve belt wrap at the supercharger pulley, which is helpful to mitigate belt slip in applications using a smaller-than-stock supercharger pulley.
No modifications are necessary for installation, and all necessary fasteners are included. This kit is not intended for use with crank pulley rings smaller than 9.55" in size.
As shipped, the kit includes the bracket and fasteners only. This bracket is compatible with the OEM crank idler pulley and supercharger idler pulley, but our billet double-bearing supercharger idler pulley offers durability, functional, and cosmetic advantages. Please choose from the option below.
Important: The bracket is intended for use with 9.55" and larger crank pulley rings only. Use with smaller rings may result in belt interference.
Note: The pulley offered as an option with this bracket is also available separately and is listed elsewhere in this section. However, there is cost savings associated with the purchase of the bracket with the supercharger idler pulley. If needed, a replacement crank idler pulley is available from GM and GM retailers under part number 12606032, and the retaining bolt is part number 11518630. These original parts are recommended for use in the lower pulley location when using this pulley mounting bracket.
