Product Details

This Westar air suspension compressor, part number CD-7718, is intended for vehicles that rely on an onboard compressor to maintain proper air spring operation and ride height. It is a practical replacement choice for owners searching for a 2006-2011 Buick Lucerne air suspension compressor or a 2006-2011 Cadillac DTS compressor-dryer assembly. This part cross-references Dorman 949-009 for the same application.

Common Problems It May Address

• Compressor failure that prevents the air suspension system from building pressure
• Slow or uneven ride-height correction
• Air suspension warning lights related to compressor performance
• Loss of compressor output caused by wear or internal component damage
• Need for a new replacement instead of a remanufactured unit

Installation Notes and Tips

Verify the vehicle application before installation and confirm the compressor-dryer configuration matches the original part. Inspect related air suspension components, electrical connections, and air lines for leaks or damage before replacing the compressor. Proper diagnosis of the full system helps prevent repeat failures after installation.

Westar manufactures this part using quality components and controlled production standards aligned with ISO, QS, and TS practices. The CD-7718 is a new replacement compressor, not a remanufactured assembly, and is built to provide an OEM-style fit and function for the listed Buick Lucerne and Cadillac DTS applications.
