Kp Component kit help ???

Aright i got the kp kit on the rear of a 99 f-150 and im haveing a problem with the rear end moving up and down when shifting gears its almost like the u bolts r not tight enough just wanted to see if anybody else had this problem the bolts was tight with a good impact and then with hand to make sure thanks

make sure that shit is up high if ur dragging i ended up dragging throug hthe cantilever bars into the bolt... so they had ot get raised up like inch inch and a half and the end of the bars re-made. and the front bars would hit and the bracket would bend out so that had to be raised too... i hate that kit shoulda just had shop make one for the price of it. That bolt on kit sucks move it up and weld it.
