Idler Pulley Relocation Bracket
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) 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 crucial in applications using a smaller-than-stock supercharger pulley.
No modifications are necessary for installation, and all necessary fasteners are included.
As shipped, the kit includes the bracket and fasteners only. The bracket is compatible with the OEM crank idler pulley and supercharger idler pulley, but our billet double-bearing idler pulleys offer durability, functional, and cosmetic advantages. Please choose from the options below.
Important Note for ZL1 Installations: In some instances, the tensioner pulley on the accessory drive will interfere with the installation of this bracket. The solution is to swap the tensioner pulley with the smaller diameter idler on the driver's side of the engine. Installing this smaller pulley on the tensioner arm provides the necessary clearance for the bracket, and the installation of the tensioner pulley on the driver's side of the engine allows the retention of the existing accessory drive belt.
Note: The pulleys offered as options with this bracket are also available separately and are listed elsewhere in this section. However, there is cost savings associated with the purchase of the kit as shown here.
