The Mercury Grand Marquis Air Ride Suspension system is subject to many problems, but TIME is its biggest enemy.  The air springs are made with rubber, which tends to dry-rot in five to seven years.  The Grand Marquis’ air ride suspension’s longevity is determined by how much extreme heat and cold the Grand Marquis is subjected; extreme conditions degrade the components. Air Lift’s sleeve design gives the best ride of any load assist product. Ride Control is engineered for 1/2 Ton and mini pickups, full-size and mini vans, and Suvs that are used for light to medium duty hauling or towing. Air Lift’s Super Duty kits are our heaviest rated kits for real air suspension muscle.

Mercury delivered the Grand Marquis with a computer controlled air ride system that used two air springs in the rear.
