Without the drop hanger it could ride rougher because of the angle the springs will be sitting at.
I did a 2"drop hanger and Boomerang shackles and it rides quite nice.
As for the steering box, You'll have to relocate it anyway so you might as well place it one time and do it right. With my drop hanger I moved my axle forward 3 inches (2 with the RUF and 1 with the positioning of the drop hanger) I did the springs first and then the hanger and then the box.
My box didn't move that far forward and there was minimal trimming to the body for the fit of the box and it still has some angle to keep a good angle for the steering shaft from the column. I also used the 3/4" less drop Pitman Arm from Sky too. It all worked out nicely. Did I mention, mine is also daily driven?
It's all pictured in detail in my build thread if you care to look.
Hope you get it figured out and get it out on the trail soon!
