Ok so I got the 39.5 mounted up and took some measurments and wanted to see how I measure up for clearance compared to some of the other folks on the boards......
with 5 psi of tire pressure I have
30.5" to front bumper
79" to top of cage
25" to frame
21" to lowest point on the belly (could probably make it 22 with out clocking the transfer case but not really worth it)
11" to the bolt of the 14 bolt
10.6" to the bottom of the 60
outside tire to outside tire is about 80"
wheelbase is 98 (short I know but until I lenghten the frame for a fuel cell it has to stay there...... 4 link is in the future)
28" to rear bumper
24.5 to gas tank
