I was looking at front axle there no way It can lower or it be bottom out on bumper rubber stop on frame. Now they only 2" clearance and I can feeling it bottom on when across potholes. I look at another truck with lower mile 70K they had 4-5" clearance so my leaf springs are sagged but that still good for aerodynamics
Rear axle I could lower about 2-3" to get level. But don't want rear end look sag while front end stand higher.
