Another 5100 Thread

[sideways91]

I've been browsing this forum for about a week and have gained a lot of good info, but varying differences when it comes to UCAs

2019 RAM 1500 Classic 5.7 Hemi
Planning on running Bilsteins @2.1 lift. 2.1 will leave me with .5" rake and I have Airlift 1000s in the back for towing.
I do a fair bit of towing, a lot on dirt roads/washboard roads, nothing too crazy but enough that I need a dependable setup.

I've seen a lot of people saying UCAs are needed for any lift and some saying that stock UCAs are good up to max 2.8" lift.
Does switching to 5th gen Mopar UCAs solve the problem or just mask it with more ball joint articulation?

2" or more front lift you want angle correcting UCA's. That will correct front end geometry and take the stress off your ball joints and CVs.

There are several great aftermarket options that will be the true fix for this. Zone is the most popular option as they are built well and solve the bad angles from the lift/level.

Message me if you would like a quote.

I did the 5100 up front on my 2019 Classic Warlock 5.7L. I think the control arms are the same as yours. I have mine at max height. Ride is good and ball joint angle looks ok. I mostly drive street and tow a 20' travel trailer with no issues for the last year. I think front end weight plays a lot into how the ball joint rest. What I did was jack up the front to the approximate lift and looked at the angle of the ball joints to get a good idea about where they would be. If I was to consider new upper control arms, I like the idea of forged aluminum like the ones offered by Rough Country.

I ran the oem on my truck with 2" lift for 75k miles with zero issues. Even when I replaced them, they were still in great shape.
