im putting new leaf spring shackles on in the rear. are there any torque specs on this ?

 

Spec for shackle nuts is 89 Ft/lbs, Do not tighten with the truck in the air. Make sure the full weight of the truck is on them at ride height.

 

thanks I got the dorman replacements oem style I guess. so top and bottom is 89fts with weight on it.

 

Man I was close, I just put shackles on my truck and guessed 85ft/lbs would be about right. haha, good to know 89 is the spec
