OK...I just swapped one set of torsion bars for another and returned the truck to the EXACT same height it was previously (where it had been aligned less than 3 months ago) do I really need another alignment?? If so, why?? Nothing has changed so why would I need the caster/camber adjusted again?

I would say no. It's probably not perfect, but lifted trucks never are. It should be fine. Hey, if it drives funky, ore you see abnormal tire wear, then get it checked out

I drive it so little it would probly take years for me to notice, but drove it to work today and it tracks straight as an arrow, no pull...so I will save the $80 or whatever for now...Thanks!!
