I just got a great deal and ordered rockkrawler adjustable rear upper and lower control arms as well as adj. front uppers to go with my Teraflex front lowers. I am not changing the driveshafts just yet, but I want to push the rear axle back at least an inch. With the lift and tire combo, the factory arms give me about 1.5" between the tire and pinch seam, and that's with a 1" body lift. I am going to cut the seam but I still have loads of room to the rear of the tire, and I have a shorty rear bumper. Will the stock driveshaft allow that much play, so that I can move the rear axle back?

 

I have the RK 5.5 lift and moved the rear axle 1" back and had no issues with the stock drive shaft before I replaced it.

 

excellent, that is exactly what I was hoping to hear. How do you like your setup, the RK 5.5 that is

 

Couldn't be happier. Love the way it performs off-road and on-road feels stock.

 

I would be concerned about the bumpstop contact if moving the axle back since the axle plates, and pads may not be contacting each other properly. Just something you may want to cvheck prior to wheeling and letting your shocks be the bumpstops since they wouldn't last long doing that.
