my buick has a custom air ride suspension. she rests on four 4" cylinders with custom built brackets. the setup consists of (8) 1/2 " electric parker valves, 1/2 " airline and fittings, a viair 450 compressor pumping air into a custom made 8 gallon tank. Its all controlled by 10 switches (fbss). the ride quality is okay, to on cylinders, but not half as good as stock suspension.
