Product Details

Westar CK-7808WS is intended for drivers addressing rear air suspension failures on the Ford Expedition and Lincoln Navigator. This air spring to coil spring conversion kit replaces the air-based rear setup with a conventional spring arrangement, making it a practical option when the original system is no longer performing as expected. Westar manufactures its air suspension products to strict industry standards, including ISO, QS, and TS requirements, and the brand positions this kit as a new replacement rather than a rebuilt assembly. This part cross-references Monroe Shocks & Struts 90005 for the same application.

Common Problems This Kit Can Address

• Rear end sagging from worn air springs
• Compressor cycling caused by leaking air suspension components
• Uneven rear ride height on Expedition and Navigator models
• Repeated air suspension warning lights tied to failing rear system parts
• High repair costs associated with OEM air suspension replacement

Installation Notes

Compatible with rear suspension applications only. Verify year, make, model, and rear configuration before ordering. For 1997-2002 Ford Expedition and 1998-2002 Lincoln Navigator, review the vehicle’s existing suspension layout and follow the service procedure for converting from air suspension to coil spring components. Part number CK-7808WS should be matched to the rear application listed in the fitment data.

Quality Assurance

Westar states that its factories use quality components and manufacture to strict industry standards, including ISO, QS, and TS standards. CK-7808WS is supplied as a new part, not a remanufactured unit.
