Default u bolt question

Just got my new leaf springs delivered today. I put in an aal in December and used new ubolts. Since the u bolts aren't that old can I reuse them for the new springs or should I get new ones

Depends on how fat your leaf springs are that you bought you may need longer u bolts now. My guess is as long as you still have a decent amount of thread showing on the u bolts after torquing the springs down to the axle you should be good.

normally, i'd say no, you will need new u-bolts.
the u-bolts are designed to stretch under torque.

but if they're quality u-bolts to begin with (black tool steel with fine thread), then i'd say re-use them.
but if they're the cheap chrome ones with course thread, get new ones, even tho they're not that old. i've seen brand new ones snap trying to torque them down.

i've reused u-bolts before and children did not die bc of it. just check on them to make sure they dont loosen up.

Answer me this everybody: so if I were to loosen my u bolts and take them off they are no good any more??? Just because they were put on once? Even if I had just put them on last week?


I have reused u bolts with no problems. I've seen other bolts break. Does that mean once u tighten a bolt it's no longer usable???
