Makes perfect sense now, Thank you.
It would be purely aesthetics for my truck, and hopefully weight savings.

I don't see it as completely necessary for those adjustments, since the drop bracket on the frame side will make that bar almost parallel the ground and have you very well set for a lowered or bagged truck.

That is great information to have as well!
Maybe I wasn't clear on my exact question, I was talking about the Tubular Trailing Arm Crossmember (PB-63-72-TACM). It has 4 vertical holes for adjustment where each trailing arm bolts up to, I'm trying to understand their purpose. Just to better dial in the centering of the rear wheels?
