Yup L/S out of the fx4 level II

 

i would just stick some gears in it and drive it. its a hole lot cheaper well if you do the work your self

 

That axle isn't worth much. Anyone who would want to buy it would likely need to re-gear. I don't see anyone "upgrading" from a 7.5 and wanting to run 3.55s.
Jeep guys won't want them because they use the explorer 31 splines that are slightly wide, stronger and have disc brakes.
