Im not sure my truck is not lifted. I did it to get the brake upgrade and get rid of the stupid hub designCould this be done using the stock hubs and Rancho 4" lift knuckles if you keep the Colorado brakes? If so, it may be worth it to get the extra stance and travel. Also, I think heavy duty cv axles are available for the H3 off-the-shelf. Lastly, it looks like this set-up is more conducive to a coil-over conversion down the road since the LCA is "beefier" and the UCA is "skinnier".
