Anyone running the Bilstein Upper Control Arms with 5100s or 6112s?

There's plenty that comes up in the forum search for Bilsteins, but i've yet to find anyone posting about running the Bilstein Upper Control Arms. Anyone actually running these things?

BILSTEIN B8 Control Arms - BILSTEIN Off-Road

B8 Control Arms are an easy to install direct fit solution designed to correct suspension geometry and increase suspension travel on lifted trucks and SUVs.

I've always been a fan of Bilstein shocks and ran a set of 5100s on my 2017 Sierra which I really liked (especially over the junk stock Ranchos). I'm considering going with a 5100 or 6112 for the front end of my 2022 AT4 and would like to install a set of UCAs along with them to minimize stress on the upper ball joint, so these seem like a nice solution as they are likely to be developed along side the shocks i'm looking to install. They appear to be of good quality, but i've seen a few things about some UCAs having clearance issues.

Would love to hear of anyone who has actual experience with these or has a recommendation for UCAs accompanying a level / lift.

Have you found out any information about this. I am trying to decide if I need to install UCAs in addition to the Bilstein (I do want to go with bilstein struts to level my pickup). Have you already performed the upgrade? Thanks in advance for the help

I have the Bilstein 5100 Adjustable front shocks - Ready Lift 1.75" leveling kit w/UCA's - Bilstein rear shocks and my truck sits almost level.

I ordered the 6120's for the front and Shock Surplus said I need to replace the upper control arms to level. They recommend the Bilstein arms. 5160 for the rear.

I've got everything, but have been super busy and haven't found time to install. I'm about to need new tires, so I'm planning to have them installed at the same time as the tires. Based on what i've read, I don't think the UCAs are necessary when just using 5100s, but I'm trying to keep options open should I decide to want more lift in the front to level the truck.
