It's not a good idea to reuse u bolts because they stretch and most times you'll kill the threads trying to get the bolts off if you can even get them off. But if all you're using is the springs and not a block stock length should work just fine.

Sorry guys but you're mistaken on the leaf spring bolts.
They are metric Grade 12.9 and are under a slight tension load when installed.
Re-use if they are not too rusty.

There seems to be 2 different arguments going on. First is leaf spring bolts. Reuse isn't a problem. Second is U-bolts, get new. The new springs are most likely thicker anyway.
