Leaf spring sag/ issues after rear bumper and armor.

[Talmond]

After adding rear bumper, armor and spare tire I’m having a whole new set of issues. Jeep is a 99 Xj with IronRock 3 inch lift and full 3.5 in leaf spring pack and Doetsch shocks. At first all seemed well noticed a little sag but no issues. Even drove to BadLands (4 hour drive) with no issues. After playing in the quarry my rear shocks were able to pull out of the top mounts I also broke a rear pinion yoke at this time. I was able to get fixed (kind of) and finish the weekend. I’m wondering what’s going to be the best option for gaining lift back after so much added weight. Iron recommended starting with their boomerang shackles and going from there.

What shackles are you running now? Spacers are easy enough for the front.

Stock shackles currently.

$43 used/returned price AMAzon
This one is a little longer Rubicon Express RE2705

Just a matter if it's enough lift, looks like it may be.

If shackles don’t add the lift back would the next step be an add a leaf in addition to the 3.5 leaf pack ?

These are da bomb, fully adjustable. Nicely made, just got them on my rig...

you may also need the shackle relocator bracket, this will allow you to maintain the ideal 45 degree angle of the shackle.

Agreed.

I'd do the relocation bracket plus a boomerang shackle.

How old are the leaves?

Leafs and entire lift is 1 year old.

HD Off-road shackle relocation brackets. Will add a little lift and most likely improve shackle angle (which greatly improves ride).

What about rear pinion angle and drop shackles. Currently my leafs have a 4 degree shim and I have the Adams sye kit and drive shaft. On the drive home I had some driveline vibes return. Wondering if the loss of lift caused this.

Whats does it look like now? If you're only adding length to the shackle you should be ok.

So add a leaf vs the drop shackle ? IronRock recommends shackles first. Is there a specific reason for this. Would adding a leaf make the suspension super stiff ?

Like I said a pic would help. Add a leaf could compromise the angle worse than shackles but can't tell you without looking at it.
