Whether you're adding A/C to your vehicle or simply updating it, there is one part you must have to make it work. Chevrolet Performance A/C compressor mounting brackets hold the unit tightly in the proper location so the belts can be attached. These brackets are purpose-built to hold solidly to the compressor. As children, many of us traveled all over without A/C; now, we can't stand going two miles without it. Keep your unit in its place with Chevrolet Performance A/C compressor mounting brackets.
