Detailed Product Information

Westar CK-7831 is an air spring to coil spring conversion kit for rear suspension service on select Lincoln models. It is intended for applications where the original air suspension has become costly or impractical to maintain, and it provides a straightforward path to restore ride support with conventional spring hardware. This part cross-references Suncore 36F-30-R for the same application. Fits 1984-1992 Lincoln Mark VII, rear. Fits 1984-1987 Lincoln Continental, rear. The CK-7831 is a practical option for Lincoln Mark VII and Lincoln Continental owners seeking a conventional suspension repair instead of continued air system replacement.

Common Problems It Can Address

• Failed air springs or leaking air suspension components.
• Repeated compressor or air system repair costs.
• Vehicle sag caused by worn rear suspension support.
• Maintenance burden from aging OEM air suspension parts.
• Need for a conventional spring conversion on supported vehicles.

Installation Notes and Tips

Verify rear fitment by year, make, model, and notes before ordering. Review the existing suspension layout and confirm that the application matches the listed coil spring plus adapter requirements where noted. Professional installation is recommended for suspension work, and the vehicle should be inspected after installation to confirm proper ride height and component seating.

Quality Assurance

Westar states that its factories use quality components and manufacture to ISO, QS, and TS standards. CK-7831 is supplied as a new product rather than a remanufactured unit.
