Longer u-bolts for zero rate add-a-leaf?

    I guess this isn't much of an issue, but I thought I'd ask anyway.
    I have the 4" Superlift springs in the rear (with the u-bolts they provided). From the top of the nut to the tip of the u-bolt, there's just over an inch of u-bolt threads left. So, it looks like when I install the 1 inch zero rate leaf, the top of the nut will be flush with the top of the u-bolt. I'm assuming that as long as all of the threads on the nut are in contact with the u-bolt, I'm OK. Or is there some sort of weird structural integrity engineering concept that requires a certain length of u-bolt to be sticking out past the nut?
    Yeah, dumb question. Just want to make sure things are safe.

    I am about to add a zero rate too, and I was advised to have at least an inch of bolt about the nut after the zero rate is in. So I would assume that you will need new ubolts.

    If you have a full nut, that's enough. Any thread sticking out is extra. A little extra length is insurance if they try to loosen up, but technically a thread out of the nut is enough.
