Metco Motorsports MRB1000 Idler Pulley Relocation Bracket 09-11 CTS-V/12-15 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 pulleys offer significant durability, functional, and cosmetic advantages.

Notes:

• The bracket is intended for use with 9.55" and larger crank pulley rings only. Use with smaller rings may result in belt interference.
• The 8-rib smooth idler pulleys offered optionally with this bracket are also available separately.
