The shock and bumpstop lengths are your limiting factors, not the arms. Unless you are planning on doing a whole lot of tweaking, I think that the stock ca joints should be working just fine for you. It's not like you are relocating mounts and running super long coils and shocks or anything.

Partially true, stops and shocks are limiting factors, but to say stock control arms aren't limiting factors isn't true. For 1.5" lift it won't make a big difference. Unless you got longer travel shocks then the limiting factor with articulation would be the bind on the solid rubber bushings in the CA. It's all depends how much flex you want to get out of that system.

Stock arms don't max out till you are over 12" travel, but by that point you really need long arms anyway. Here is one (not mine) from another forum. I'm not saying to not replace the arms with a better flex joint, but they are by no means the limiting factor. <img src="https://www.jk-forum.com/forums/attachment.php?attachmentid=625089"/>

You are not going to see any benefit from going to an adjustable arm with a different joint in terms of flex at your height and shock length.

This might be off topic but I have a two door jk with 3.5 inch of lift and 33s. I recently bought front and rear drive shafts with double cardan joints on the transfer case side. I know the pinion should be in line with the shaft but whoever lifted my jeep didn't change control arms so I have factory ones but would I need rear control arms for the rear pinion angle

I read your original post. Here is my question. I just purchased a 2010 4 door 2 wheel drive wrangler for a b day present for my daughter. I know absolutely nothing about jeeps. The jeep is 100% stock. She will most likely never go off road. We both like the look of non stock wheels and tires with a more aggressive look. My question is....what would be the best wheel size without sacrificing drive comfort etc? This will be a daily driver for her. The tires on the wrangler are P255/75R17. 
These are 17X9 with 4.75 back space. Could I use the tires are mentioned? Is the 4.75 backspace correct? I don't want the tires to stick out much past the fenders. Any advice? Thanks in advance.

Your question may be better off in the Modified area instead of the thoughts on lifts, but...
Backspacing on stock rims is around 6.25". Going to a 4.75" will move the tires out appx. 1.50", with some variance for the difference in rim widths. Grab a ruler and go do some measuring to see what you think of the fender coverage.
Go to your tire mfgs website and check the specs for that specific tire. It will list the mfg's recommendation for rim widths. Those 17x9 rims are probably wider than the recommendation. Many people are running this setup without issue, just worth noting that some shops may not mount tires on rims that are wider or narrower than the mfg's spec. If you run into that, find a different shop. You will also probably want to do a chalk test to find the inflation that will give the tires a good footprint.
