I have an 08 Rubicon Unlimited with 2.5in lift with half in spacers, with an RE front trackbar, and a relocated rear trackbar. I was wondering if I were to add Teraflex rear upper control arms would that benafit me in any way? I have Teraflex front lower control arms but stock in the rear. Just wanted some feed back thanks. I am running stock tires but plan on going to 35's soon.

 

If you're still runnin the stock rear shaft, you don't need them. When you get an aftermarket shaft you'll need them to adjust you pinion angle. The stock rzeppa joints are very forgiving on the rear of a 4dr. That shaft will last a long time unless you bash it into something or twist it off.

 

Would there be any reason why I would have to change the stock rear shaft if I plan on staying with just 3in of lift or maybe go to 3.5 of lift? Thanks

 

See above. Also, the only other reason that may or not make a difference to you is the ease of changing a busted u-joint on a trail vs having to change out a whole shaft( if you carried a spare stocker) and or end up with no shaft. My rear stocker has lasted to 60,000m with 4+ in of lift, just changed it out.

 

Thanks for the info.

 

How steep was your pinion angle with that much height? Did you use correction wedges if coils were bowed? I'm sitting at about 1.75 in rear(2.5 front) and am slightly concerned about my 7 degrees and the small bow

 

I have almost 5" of lift in the rear and I run the stock shaft without any issues.
