Have you measured your up/down travel on your setup? Front and rear (mostly interested in front, but also rear). Also do you think the UCAs were super necessary with that setup or just nice to have?
I know for sure I have 1.25” more down travel due to the Uniball joint having more travel range then a typical ball joint setup. I haven’t checked up-travel but on initial install I know for sure it’s at least 2” more compared to the stock setup.
Choosing the boxed arms and uniball was just about strength, it is a Suburban so we are north of 6k without cargo and people already and it can take the extra beating on washboards and other rough activities.
