Pull the leaf above the overload and leave the overload leaf in. It just depends on how many leafs you have since it seems everybody has 3-5 just depends on the truck I guess.

And yeah you could flip the leaf and push the axle into the frame but you don't want that. A buddy of mine has 5/6 and is 1.75in off the ground. We're out cruizin' last night and he can't make it over an bumps in the road let alone a speed bump without draggin his frame. His cat has a hole in it cuz of it and it now sounds like my 4cyl.
