What It Helps Address

• Restoring A/C service on fixed-orifice GM SUV platforms
• Replacing worn or mismatched ancillary A/C repair components
• Correcting system issues on Trailblazer and Envoy models with no rear A/C
• Supporting repairs after compressor, line, or orifice-related service
• Matching the listed application-specific A/C configuration

Installation Notes

Verify the vehicle uses a fixed-orifice A/C setup before ordering. Confirm whether the vehicle has rear A/C, since the fitment notes exclude rear-A/C applications on several models. Compare the existing system configuration and part references against the fitment data for the exact vehicle.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Quality Assurance

Universal Air AK1072 is cataloged as an ancillary kit for the listed GM and Saab applications. Review the fitment notes carefully to confirm the correct platform, A/C configuration, and companion component references before installation.
