LS/LT Accessory Drive Bracket Kit
Holley is pleased to offer a solution to the accessory drive challenges encountered when swapping a GM LS engine into another 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, but allow you to choose the source for supplemental accessories and components that are often already on the donor engine or host vehicle. A Fitment and Required Components Guide helps you locate and source components and provides other notes and helpful hints.
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 # 21-1, 21-2, or 21-3) is REQUIRED for most applications. Replacement hardware kit is 97-171.
