If you're too cheap to get real springs, you can get junkyard springs (Chevy 1/2 tons, F150's, Waggy's, etc), or use a combo of longer shackle, add-a-leaf, or shorter block with current springs.
Or, you could just get a wrap bar!
The common prob with blocks is axle wrap, which is probably what caused your ubolts to break. A wrap bar will stop axle wrap, which won't break ubolts.
All depends on how much money/time you want to spend and how good of a suspension you want.
