Physical difference I don't know the difference. They do show a different part number for the 1/2- light duty 3/4 ton to the heady duty 3/4 to 1 ton. All I've gathered so far just from looking up parts is that they use the same lower ball joint. Upper is different but only difference I can see just from pictures is the mounting surface. From the pictures I have looked at the upper control arm is made up different between the two as well. I just happen to look at a buddy's 1/2 ton 4wd upper control arm this weekend and it looked like it was the same as the heavy duty 3/4 and 1 ton 2wd. I'll have to check it out. I'm sure it will lead to nothing but anything is possible.
