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. <font color=blue>Rob 85 K5</font color=blue> 24 beers in a case, 24 hours in a day - Coincidence?
