23 Trailboss UCA same as 21 ?

[07blackz71]

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.

Is this actually a widespread issue?

If you lift it more than the 2" stock and don't replace the upper A arms it can be.

You can do a lift of most any size with $ and proper engineering.

Triple shocks per side in the back and triple steering stabilizers! Did it have triple shocks in the front too?

 

[Jmzvet]

Pretty sure it was quads up front. I may have to dig into a real “non digital” photo album to confirm

Those were probably only 32" tires too! LOL
