[cbbs02]

OK maybe im completely retarded. im looking at redoing my front suspension, i would like to eventually go with an air ride system, im looking for tubular control arms. i have found many within my price range bur every one says for lowered trucks! i how ever like the stance of my truck now. if i buy a set that says for lowered trucks are the tubes bent at different angles than they would be if it were remaining at stock height? also i cant find any that says for 3/4 ton, are they the same? or do i need to worry about different ball joint sizes? please help
