Unity 65003c Rear Conversion Kit for 1992-2002 Ford Crown Victoria, Lincoln Town Car, Mercury Grand Marquis

Unity 65003 Rear Conversion Kit

The Unity 65003 rear conversion kit replaces factory air suspension with a passive steel-spring setup on 1992-2002 Ford Crown Victoria, 1990-2002 Lincoln Town Car and 1992-2002 Mercury Grand Marquis models. It is designed for owners who want to eliminate recurring air-ride leaks and compressor failures. The kit provides a direct-fit solution that restores consistent ride height without electronic controls.

Replaces air springs and compressor

This kit removes the original air springs, height sensors and compressor assembly that commonly develop leaks after years of service. The jump is worth it when the air system no longer holds pressure or when repair costs exceed the price of a permanent passive conversion. It is not for owners who wish to retain adjustable ride height or automatic load-leveling functionality.

Steel springs maintain rate under load

The passive steel springs deliver a fixed spring rate that does not change with temperature or system pressure, so rear ride height stays stable during extended highway driving or when carrying passengers. There is no compressor cycle to wait for and no air line to rupture under sustained weight. The setup behaves the same on the first mile as it does on the five-hundredth.
