    This Holley bracket relocates the A/C compressor on GM LS/LT engines using a Corvette-style accessory drive, positioning it high above the cross-member but below the hood line for easy installation and a clean look. It accepts a GM R4 compressor (Sanden version also available) and uses factory spec flanged-head hardware to match factory LS engine fasteners.

    Specifications:

    • Accessory Drive Style: High-Mount
    • Engine: GM Gen III/IV (LS)
    • A/C Compressor Type: R4
    • Finish: Black
    • Material: Cast Aluminum
    • Mounting Hardware: Included
    • Part Number: 20-133BK

    Works with the R4 A/C compressor and Corvette driver's side bracket. Requires an application-specific installation kit (21-1, 21-2, or 21-3) — see Holley's fitment guide for the correct kit for your setup.
