help the rear suspension
my 99 f250 psd is sagging a little bit in the rear end, and i want to tighten it up a bit. ideally i would like to put in an air bag kit in, but i can't swing the 400-500 bucks for it. so i was thinking i could just put in some add a leafs ($100ish) for now. as it is now the trucks sit level, and i don't want the rear end to sit up more than the front after i add the leafs, so if i install leveling shackles in the front along with the extra leafs in the back, should i have any problems?
let me hear what you think
