GM 8.25 IFS Front Ring & Pinions
It's a GM 8.25 diff. Don't know if that ratio is available.

sweet, thank you. Why do they offer a 4.11 for the front and 4.10 for the rear?

The real answer is because you're not supposed to use 4WD on dry pavement. The ratio difference is for pull vs. push. It's not common any more to split the ratios like it used to be unless you have really big tires or you use the truck for specialized activities. Not sure there is a modern 3.90 gearset.
If it's not a big deal to have a difference of .01 in gear ratios between the two (which i really doubt), then I'm fine with it. If anyone does find a front diff. 3.90 ratio (strange engineering has one for the rear diff.) please let me know.
