Holley Ls/Lt High Mount Accessory Drive Bracket - Sd7 Compressor - Cast Finish

Holley is delighted to present straightforward, tidy, and cost-effective solutions that address accessory drive challenges encountered when integrating a GM LS engine into various vehicles, such as muscle cars, trucks, hot rods, and more. These brackets are meticulously designed to provide a factory-style appearance, ensure correct belt alignment, and maintain factory stability.

Please note: This bracket REQUIRES an installation kit for assembly (Part 21-1, 21-2, OR 21-3, see Fitment Guide below for the correct installation kit for your application).

Holley's kits provide the necessary brackets and hardware for installation, giving you the flexibility to select supplemental accessories and components, often already available on the donor engine or host vehicle. Whether you're sourcing from a salvage yard, local auto parts store, GM parts dealer, or Holley, you can choose accessories that align with your needs and budget.

A Fitment And Required Components Guide assists you in locating and sourcing components, offering additional notes and helpful hints. Three straightforward steps guide you through the process. Step one is to determine your belt alignment based on your crank pulley position on the engine. Step two is to choose the Holley accessory drive brackets needed (A/C, Alt & P/S or both). Step three is to identify the Holley installation kit your setup requires to align 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.
