Tried about 6 different brands and never found one that would last and clamp properly behind the GM OEM wheel covers on our 08 3500.
Now use 135 degree extensions on the inside wheels and struggle when checking/adding air. The Toyo's (High Country Tuff Duty) that I am running have minimized that, thank goodness.
I use steel braided extenders bought on Amazon. Don't Remember the brand. Comes with clamps that are held by the lug nuts. Had to cut a notch on the center hub cover for that configuration. On the truck three years with no problems.

We just got some extenders of the proper length for our inside dualies at Wall mart .We can not get the TPMS to work on the inside dualies. We have not had a problem in 10 years and two dully trucks with the extenders.
