Default lengthening wheelbase and compatibility issues- need help

So I've moved my rear axle back so it is centered under the wheel well with my 4.5" coils. I angled my pinion up a bit to lessen the angle on my stock DS which runs smooth now but my shocks are a bit squeezed into the axle mounts, sway bar links get close to hitting the uca mounts, and the rear track bar hits the diff cover when bouncing up and down. I will eventually need to move the pinion angle up further with a CV driveshaft but this will make the the sway bar links and shocks hit for sure. I am assuming this is all due to how far back I have the rear axle, but I like where it is and it's centered (if anything a hair forward of center).

How have you guys been dealing with this stuff once moving the axle back and adjusting pinion angle? I was thinking to trim my shock mounts and install a rear track bar relocation bracket to lift it, but I already have a JKS bracket welded on... not sure about the sway bar links. advice anyone?

How far did you move it back?
On my RK lift the axle is moved 1" back.
It required also moving the rear sway bar frame mounts back 1". The kit had some self tapping screws that were used after drilling a 5/16" pilot hole. Fairly easy.

I don't know exactly how much it moved back, but it's about an inch. moving my sway bar back would definitely help. your shocks aren't contacting the mounts and your track bar is not close to the diff cover?

My rear track bar that came with the kit clears fine. I didn't notice any issues with the shocks. I'll have to have a look this evening.

you mean you ditched the rear track bar, right? I know you don't have a rear TB. Or did you get rid of the sway bar too?

Oh nice. I was thinking of something similar. That would definitely help. Did you make that bracket or buy it? I don't have the ability to fab stuff up.
