    This complete Holley LS high-mount A/C accessory bracket kit relocates the compressor up high and away from the frame rail, eliminating the need for notching. It's built for owners who already have a donor engine's P/S pump and alternator system, and includes the compressor, pulleys, and tensioner from OE part suppliers, finished in polished aluminum.

    Specifications:

    • Accessory Drive Style: High-Mount
    • Mounting Side: Passenger's Side

    • Finish: Polished
    • Material: Cast Aluminum

    Kit includes: 20-134 LS A/C bracket, 97-151 tensioner assembly with grooved pulley, 97-150 smooth idler pulley, and 199-102 SD7 A/C compressor. Requires a separate application-specific installation kit (21-1, 21-2, or 21-3) for assembly — see the instruction sheet for the correct kit.
