whats the torque spec for u bolts on a 94 f150?
also theyre not stock size, theyre for 4" lift blocks and add a leaf
thanks

 

Due to stretch and twist of a ubolt, there is no way to get an accurate torque, 1\2 bolts usually torque at 85lbs, try that and use a reg ratchet to check for tightness, or just drive the nuts on with an impact wrench.

 

Hammer them down with an impact, drive it a couple times, go back an do it again just to be safe an yer good to go. Like he said its tough torquin U bolts.

 

Suggest for good measure to ensure that the threads are somewhat clean. Can waste a lot of torque overcoming crappy threads, resulting in less-than-optimal tightness.

 

i recommend re-torquing after a day or two of driving, just to be sure
