yes, you might see the wheel move back when you lift the front, I just use my son-in-laws (both named 2 ton Jack) and step back for a look.
removing one leaf is easy 2-2.5" drop and doesnt make it too bouncy. I have heard that ZQ8 are Z85 with the bottom leaf removed. I removed the middle on the last truck.
here arethe measurements of the socket cap screw I used for the center bolt, the original isnt threaded enough to go back on. I just sanded the knurling off and it fit the axle.
