I am in the middle of putting on my sky jacker 4" kit on my 40 and was wondering how tight to torque the u bolts?

thanks

Make sure to do each side evenly. If you just sit there cranking on one side, it will twist/not sit flat

Torque them up as described by the previous replies, then do it again at least 2 more times.
Seems like the dang things stretch a bit with use.
I got a couple of turns on each after a few miles.I had new CCOT U-bolts and springs.

initial torque, 80 ftlbs. after 1 week, retorque. one month later, re torque again....

I've read 60-80-100 for u-bolts....not honestly sure which is correct. I've made a habit of overtorqueing mine...heh

I asked a similar question when I did my 4" Skyjacker lift. In the end I went with 90 ft/lbs. As nothing stripped, I'm assuming that the nuts & bolts are happy with it. :)

As Woody stated, re-torque them repeatedly. After my installation, I drove about 5 miles, and the next morning I ended up putting several turns on each & every nut. Since then, I have re-torqued them at least 6 different times. One thing that I can say is that each time I get a little less movement before the torque wrench clicks.

if they are loose, you'll feel it. The car will kinda twist when you aply power, happened after like 4 miles of driving, retorqued and went away
