I spoke to tinworks, he's looking into if he can shorten up the bracket any for me but he designed these to run with no air until loaded. If you raise the truck with them they come out from inside the wheel an rub.I run about 15 in the helpers on my daily NBS 1500, that seems where they're happy. You can grind the fenders or they'll smoke like a sumbitch going down the road.
Him an Lowboy both told me the fender will need trimmed regardless of tire size. Not sure why lowboy didn't tell me that up front. I thought these setups were good to go, no fender or rear end mods needed. Ya that's how I noticed I had a problem, it was smoking like crazy. It almost rubbed the letters off on the Dr side
