We're looking to get Superpro as well. Highly recommended by a friend mechanic. We'll start the mod project this weekend once we mounted the rear bumper, winch, and dually wheels on the F350.
Looking nice! I'll see if my friend would like this. He'll start the interior mods next. It's in the shop for the installation of the new tires from 4Wheelonline.
My friend is looking at this 11th gen with Swift Spec R springs and the owner mentioned it does make an intermittent noise and it doesn't annoy him. We'll take a look at it this weekend after we installed the brake pads and wheels on the truck. It seems going back to oem is a better choice.
