    These accessory drive brackets from Holley are great when swapping a GM LS engine into a muscle car, truck, hot rod or other vehicle. These brackets were designed to deliver a factory style appearance, correct belt alignment, and factory stability.  Holley's kits supply the required brackets and hardware needed for installation.

    To determine correct application, these three easy steps will help get you going:

    • Step one is to determine your belt alignment based on your crank Pulley position on the engine you have.
    • Step two is to choose the Holley accessory drive brackets that you need (A/C, Alt & P/S or both).
    • Step three is to see which Holley installation kit your set–up requires to line up your accessories with your crank Pulley position. An application specific installation kit (part # 425211, 425212, or 425213) is REQUIRED for most applications.

    Note: When referring to guide links below, keep in mind that part numbers shown are MFG numbers without "425" prefix.
