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.

Anyone?

 

To clarify I thought I read that all models from 2019-2021 used the same UCA.   Then in the refresh they had 2 part numbers.   One for regular models and one for the factory lifted models.

They changed the arms, yes for 2023.  Trail Boss/AT4 and ZR2/AT4X use new p/n upper control arms.  

 

2022 refresh Trail Boss/AT4 and ZR2/AT4X use the same arms as the non lifted trucks from 19-22.
