what exactly are you looking for? what tire size do you plan on running? im gussing you have an HP dana 30 in the front now, and that axle is great with just adding alloy shafts. then you could easily put a ford 8.8 out of an exploerer for the rear. the front hp 30 is limited to 4.88 gears, so if you plan on goimg larger thatn 35s you should look at another axle.
hope that helps, i have been doing ALOT of axle research latley!
