UCA 4WD vs 2WD

[isay77]

I have a 2014 Ram 1500 Lone Star 5.6L 2WD truck. I want to level it but I need new UCA. Is there a difference between the 4WD UCA and the 2WD UCA.
Also, the only 2 real options out there is the Movtech and Readylift from what i have seen. Movtech is about $100 for the pair, but there is no curve to it and Ready Lift is about $700., but it is made for lifts and levels. Has anyone seen something that is maybe in between the 2. I don't need uniball but maybe grease-able.

I honestly don't see a difference between the 4wd version vs the 2wd however with that said if you run into a warranty situation I'm positive they will deny it because it we the wrong version for your truck.
