Suggestion - Google "U-bolt torque"

All depends on the size (diameter) u-bolt. I used this table: http://www.autoandtrucksprings.com/pages/U-Bolt_Torque.html

That might have been my tech article. Thanks!

Same for the spring tie bolt? Just use the same chart? Thanks!!!!!!!

Same for the spring tie bolt?

Sorry, missed that the first time around.

You talking about the spring center bolt? The one that holds the spring pack together, along with the shim? I use standard bolt torque specs. I think that's just a 3/8" grade 5 bolt. Spec is around 25 ft/lb. Here's a bolt torque chart.

Re-torque u bolts after driving first time. Check torque after a couple of hundred miles. Check torque before any off road trip.
