I don't know the specifics about the system, but I do know if you are going to have anything in the rear seat or trunk you need the air sus. I had a 91 NY and it really went down with a load. My 92 Imperial doesn't, due to the air shocks in rear or air suspension. Are the shocks only avail from Chrysler or is there an aftermarket? I know there was some discussion about the struts being very $$ and I'm fortunate my car does not have those. ----- Original Message ----- From: "Brad Hogg" <roadhogg@xxxxxxx> To: <mailing-list@xxxxxxxxxxxxxxxx> Sent: Saturday, August 17, 2002 1:38 PM Subject: Re: IML: 1990 Imperial Coming Home > >From what I can tell, the suspension is indeed "air ride".
