^^^ same here, we have a 2012 5.3 work truck with 2000 miles and i never can feel the transition. On our 2014 it is very noticeable, almost feels like a shift.
just from looking at the pictures i was surprised when you said no trimming. Does it only rub in reverse with the wheel turned all the way to the left and on the drivers side?
