what newer GM trucks/SUV's have IRS?
 

just curious...I know that the f-word is putting IRS in many of their newer SUVs and while I would like to convert my truck to IRS at some point in the eventual future, I believe that "built ford tough" is best done with chevy stuff....

All GM SUV's and Trucks have been and are still straight axle rears. Most of the 01+ SUV's now come with 5 link suspensions. :D

I think the Nissan Armada SUV has IRS.
