if you want 3" of lift, then don't do SOA. that will net around 5 or 6". check out hell creek for their full leaf packs. that would be your best bet. (they even give cc discounts )
try contacting JKS. my buddy broke one end off of his (completely his fault and told JKS that), yet they still sent a replacement for the price of shipping. they didnt like that fact that one of there products broke, even if it was user error.
went to the junkyard with my buddy, Mr. cordless sawzall and came back with these babies. pretty much perfect rockers/cab corners. next weekend starts the surgery :D
