I have extended shocks and Britt Part HD 2" lift springs. I think the disconnect is the way to go as this is on the road a lot and also has a roof rack, RTT, hi-lift and all my junk in the back making it very heavy.
Cant' really do anything until I go with the longer brake lines anyway.

 

Found this info on discoweb also. Thought I'd ad it for anyone coming across this thread looking for similar info.

That's the writeup I used to install mine, but those are front disconnects like I have. Email Justin@Lucky8llc.com to get the rear ones.

 

Yes they are fronts, and it is an interesting write up.
