    Difference between 4WD and 2WD Rear Leaf Springs?

    Hey guys, wondering if anyone knew if there was a difference between 2wd and 4wd leaf springs on the 99-07 1/2 tons? The GM parts catalog does in fact list two different part #'s for 2wd vs 4wd leafs.

    I have only noticed that the 4x4 leaf has a small block in the back. Maybe they include that when you order the springs from gm because that would be a ware part. And the ubolts are longer on the 4x4 trucks.
