The distance between the top of 2"sq. tube and the bottom of the axle is 1 1/4". That distance is when all is level. The minimum distance when the front axle is at full travel is 1/2". To get my clearance spec. ,I jacked up the front axle. I then pivoted it thru it's full swing and took measurements. You also asked for the distance between the 2"tube,It is 6"to the inside edge. Hope this info. will help. /forums/images/graemlins/smile.gif
