So far as I know, the replacement frames are identical to the factory OEM ones (just rust-treated according to the original specs that Dana couldn't seem to follow ...).
The more likely explanation is that your suspension had 'settled' over the years and the disassembly / reassembly process (perhaps combined with new replacement parts here and there) put it back 'up' to original stock height.
What was included in the 'bunch of other stuff' they replaced?
