Holley’s Accessory Bracket Kits for GM LS engines have already become a popular product in the LS world, and now they’re proud to offer them for the popular Sanden A/C compressors. They are a simple, clean, cost effective accessory drive solution that solves the challenges encountered when swapping a LS motor into a muscle car, truck, hot rod or other vehicle. These brackets look truly at home on any LS engine as if they came from the factory this way.

Key Features:

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. Whether sourcing from the salvage yard, the local auto parts store, your GM parts dealer, or Holley, you pick the accessories that match your needs and budget.

A Fitment and Required Components Guide helps you locate and source components and provides other notes and helpful hints.  Three easy steps will 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). Now you get to choose what A/C compressor you prefer; the R4, SD508, and SD7. 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.
