When you install new u bolts and have to cut them down, how much thread do you leave above the top of the nuts? You still need enough so you can re-install them, but not too much.

So whats a good length? 1/2"? 1"?

I figured I may need to slip in an add a leaf later so I left an inch extra from top of the nut. First tried with reciprocating saw. Torched 2 blades then went for angle grinder with cut off wheel. Much faster.

do you guys tighten them in any specific sequence? And do you torque them to a certain ft/lb or just crank them down with the hand of god?

I got 5/8 u bolts from ruff stuff that are pretty snug but I figure after I put a few miles on it I will have to go back and re torque them

Tighten them opposing corners. Grade 8 5/8s ubolts get torqued to a max of 132 ft lbs.

Yup, angle grinder has been my go to on u-bolts for sure. Run the nut down, cut it off with a thin blade, bevel the edges with a flap disc or similar, then run the nut back off to catch any burrs.
