I am currently in the process of cycling for Rancho RS5000x RS55239, 2-3 inch lift shocks, in conjunction with Currie TJS bar and 32s.
As I wanted to test the fitment before drilling, I have the axle side in with the factory bolt and flag nut, and I have the frame side ziptied in. I am wondering how much my measurements will be affected after having the track bar fitted tightly in, as I'm dealing with some major interference at the diff cover at full bump.
It's not the cover itself that's the problem, but the bracket that extends from the back side of the Currie bar hitting a diff bolt. If this bracket could be cut out the bar would probably clear at full bump.
When jacking up only one side at a time there are no clearance issues. With only one shock in at a time I measure 1.625 inches of additional bump stop needed, this is not including the 3/8ths factory weld on stop that the Rubicons apparently(?) came with.
With both shocks in at the same time, jacking up the driver side results in 1.625 inches additional bump stop needed, passenger side 1.875.
The scary part is when I try to full bump it. I jacked up from the center of the axle tube right next to the diff, the passenger shock bottoms out with 1.5 inches between the cup and pad. Then I try to get the driver side to do the same, however before that can happen the track bar interferes, with 1.25-1.37 inches of driver shaft left. If I were to set the bumpstops for this interference point, it would require 2.875 inches of stop on top of the 3/8ths already there. This cannot possibly be right, or an ideal setup to say the least.
I wouldn't think jacking up from the diff would be the right way to check full bump as it's not centered, but I tried it anyways. When I try to jack from diff neither shock bottoms out before track bar hits the diff bolts. Measuring the disance cup to pad, 2.25 inches of bumpstop needed for the bar, with .75 inches of driver shaft still showing.
So what should I do? Cut the tab off the track bar? Or drill the mounts and restart the process with track bar bolted in?
