Duramax mechanicin' question

I dunno, I was assuming so since the guy started talking about torsion keys. I'd assumed he at least looked at his truck before asking something.


Edit- Looks like the 2500's still have torsion bars.

 

I did have to look, but it was before I asked the question. I knew GM did redesign the entire suspension and frame on the truck. What is odd is on the GMC site they advertise "Adjustable suspension trim height" for when you add weight to the front end. They make it sound like no big deal.
