Are the upper control arms the same on the 2023 Trailboss as the other years like 2021? I thought I read somewhere that they use a diiferent ones now to correct the ball joint issue.
 
I thought I read the all silverados from 2019-2021 use the same UCA. And in 2022 or 2023 they had seperate ones for regular silverados and another part number for the factory lifted models.
 
Same, but I can't seem to find the thread here or on the other forum I'm on that gave the part numbers from some one that worked at a GM dealer.
 
My truck when I was 18 and had little money and less engineering skills🤣

Triple shocks per side in the back and triple steering stabilizers! Did it have triple shocks in the front too?
 
Pretty sure it was quads up front. I may have to dig into a real “non digital” photo album to confirm 🤣
