so if someone decided to swap the axles in a 4400 to a more common dually 8 lug does that mean its not really a big bolt anymore? wouldn't that lower the gvwr but lighten the truck so would it really make a difference. opinions suggestions. pictures. i like the idea of running big rig wheels and tires. keeping kind of original looking. the 8 lug to 10 lug adapters are ugly and clutter a full floating axle.
