Has anyone flipped the rear axle under the leaf springs or know anything about it? On my truck the axle sits above the leafs so I believe it is possible to flip this to sit how the full size trucks do. I have a broken leaf spring that needs to be changed soon anyway so I am thinking of doing...

So, it's come time to replace my leaf springs. Before I actually buy them, I'm looking for a list what else should be bought when I make my purchase. 2006 colorado crew cab z85. I will be having 4" drop blocks come my way shortly, and from what I've heard, I may need to buy beefier ubolts...
