Spring & Shackle question

Ok, I built some spring shackles from measurements from another set of shackles i had around here and now I'm ready to install and I have a gap from the bushing to the shackle(see pic below). Can I make a spacer or longer center sleeve? Does the bushing need to be touching the shackle ? I've heard I need to torque the bolt but with the center brace not sure torquing will matter... Any input would help a ton guys.... Thanks

get rid of the center brace. the side plates need to be torqued against the bolt sleeve, which needs to be exactly the right length to keep the shackles straight and move without binding.

95 and 105.

If you have to leave the shackles loose, you have the wrong metal sleeves in the bushings. Mine are torqued to 95 lb ft and 105 lb ft. It would ride no different if I left them loose.

ok thanks... I am going to replace the frame bushings first tho... I can see the rubber is blown out past the sleeve and i think it will bind when I torque.... Whats the best or easiest way to replace these ???

Not to contradict any of the others advice, but I do notice that you've got the bushings pushed together and you're assuming that means there is a problem with the width. Not so. The poly bushings don't necessarily need to be touching in the center of the spring eye. What matters is the length of the sleeve bushing on the bolt, which isn't shown in that pic.

Warrior Products, which look a lot like your shackle, recommends 30lbs for both ends of the shackle.

if you are going to do 30lbs make sure you use nylon lock nuts

6 of them are nylon (they came with the shackles) the other 2 are rust-tighted OEM.

The bolts WILL wear out and eventually fail. Hopefully this will not occur on the highway.

What is the reasoning behind this, they are torqued to manufacturer spec, My Jeep rids so much better now than it did before loosing up the shackles (I had to use a breaker bar to get the bolts loose)

the nuts should be torqued to the center spacer sleeve- they shouldn't be clamping down on the bushings beyond the manufacturer's intended design. That is the only way you will be binding.
