I changed the rear, worn out, air lift shocks to Gaberiel ready monuts. Pretty straight forward and easy. My question is, my rear end rides a little lower than the front, which is still stock (I can fit two fingers between tire and fender in the rear, but four in the front.). Is that normal for a conventional replacement? I have yet to buy the ready monut's for the front. It rides fine, just looks a little weird to me. It's a 93 Sedan Deville with 111K miles.
