On the Rubicon's ( because of the wider axles ) you can go up to 4.75" without an issue. We do have customers that are running 37's with the stock XR package wheels. They list as a 4.4" bs but have herd might be closer to 5".
If you do try to run the longer shocks for the 4.5-5.5" kit there may be limited up travel. If you are on 40's and running about 4"of bump stop it can work.
Looking at the pic of your drag link it is rotated up at the bend farther that it is should be. The bend should come forward to clear the stabilizer. If you loosen the jam nut you should be able to roll it down a bit.
We have no problem getting you taken care of, but I mentioned both times we talked I need the measurements and can send parts to get this addressed. We do have different upper isolators to address the lean as GatorB8 shared.
Looking at the bar it does look like it comes up a lot higher than our bar does and maybe more than the stock one. It may not with with the bar without excessive bump stopping.
@GATORB8 Thank you for tagging me in this. This is something we have been working on for a long time to address the issues we have seen with so many stock joints in these things. Mine had signs of wear at 13K miles.
I know we have a lot more info coming for them in the next couple weeks to...
The rear mounts should clear depending how they run the mounting to the rear body mount. The arm running into the rocker at full stuff would be the issue.
We might offer the rear by itself later.
