@Jasfish18 something to clarify for you.
You don't need the 2" bumpstops per se, that will depend on what shocks you run in the back and how big your tires will be. you want 2" bumpstops in the Mopar kit because of the lenght of the shocks they give you with the kit which also matches the extension you get out of the SLF-140 coil springs. The springs are so long you'll have to compress the fackers to get them in even if you disconnected the trackbar. You could disconnect the rear control arms out and get more droop that way if you didn't have spring compressors. Anyways, the shocks Mopar give you are Bistein 33-185569 and they're long suckers at 29.7" extended, 18" compressed. Stock shocks are 25.50" extended, 16.50" compressed. i've used the SLF-140 springs, they're 22 1/4 long (free lenght) as opposed to the 18.25 stock free lenght.
You can do Icon 1.5", eibach 1" or Bisltein 1" rear springs, and run your 1" 5100 everybody and ther sister recommends around here
, part# 24-187374. they're 26.7" extended and 16.75" compressed and do zero bumpstops. my current rear shocks are 27.25 extended, 17.5" compressed, and i only run 1" bumpstop, not really needed but i run my chit a little harder than some with 37's with the Icon springs and a 1" spacer. you can run 17.5" compressed rear shocks without bumpstop extensions if you wanted, but again, all depending on what your setup is. Mopar goes on the safe side and give you 2" i'd guess because you can stuff the tires all the way that way without having to hit the plastic fender wells.
If you're going to have weight in the truck bed, big spare, tool box etc, etc, you won't need TB relocation anything. I sagged the full 2" in a matter of couple of weeks with those SLF-140 springs and about 300lbsbs in the bed, i added a little more weight and it wasn't funny anymore. Would have been a waste to spend relocation anything since i was literally at stock height after just couple of weeks.
Brand new SLF-140 springs, i had a mission to get longer King shocks. you can read my journey in only 15 days after this post. They sagged their full weight so i returned them little after 15 days

Granted, if you wanted full offroad long springs setup with any shock that can give you 30" extended, the rear will flex really nice with those SLF-140 springs.
As far as brake line extensions. $2-$3 at Lowes and you're all set, you won't have any issues running those 30" extended shocks if you wanted.
