Comments about Monroe Max-Air Air Shock Absorber:

Put these on my 94 G20 conversion van. Installing the shocks was fairly easy. The lines were another matter. Be careful when running the lines - there is no room for error in the length of the lines with the shocks off set. The hook up of the air lines seems a little cheesey, to me, and had trouble with air leaking out of the lines from the connecting points. I used some high temp silicone to help seal up the O-rings (hope that wasn't a mistake!) Aired up to 25 PSI and seem to be holding. Balance looks good (rear end was sagging prior to installing these shocks) and want to pull a motorcycle trailer. Haven't taken the van out for a test ride yet. Will comment later if there seems to be an issue.
