To all the nay-sayers... If you had read the OP's message, he said he was looking for an inch or 2 lift, so that's hardly the weight of the whole car on the shock mounts.
Just for the record, I have Monroe air shocks on my Dart as we speak, and with less than 40lbs of air,they give me the inch or 2 lift I want, and ride great!!
Yes, I will agree if you put 300lbs of air in them, the cars' gonna ride like a stagecoach.
