I have a 2019 Big Horn 4x2 (6’4” box) with the 2” Mopar lift, the first 2 dealers I inquired with said it could not be done, the third (also the one who did the install for me) said that they “are doing them on 4x2’s all the time”.
I have had no issues (been installed for about 40 days, 1000 miles) ride is just as good as stock.
Trying to figure out if the actual lift they put on is pre or post TSB, front still looks a little low... if it is post TSB and this is all the height I’m going to get out of the Mopar lift, I might try to add the ORG springs to gain another 1” of lift in the front. I got the idea from this forum, only wish I came across the thread prior to having the lift installed as it would of only ran me an extra $100 for the ORG springs, that’s if it’s even possible on a 4x2 - which I don’t see why not.
