Do you know of anything better?

In the lifted realm, the general consensus is 4.56's for 35's. By the math 4.10's are the logical choice, but you have to take in consideration the extra unsprung mass of the 35's vs. the much lighter stock 31.5's. For example 35x12.5 Toyo MTs are almost 85 lbs per tire, not including the wheel.
Yukon gears are the way to go. I have been running Yukon 4.88's for 40k miles and quiet as ever. Also if you want my opinion, if your looking at re-gearing. I would ditch that G80 (it is truly the weak link in the GM 10 bolt) locker in the rear. Put in a Auburn LSD (I have), or if you do a lot of off road driving, the Detroit Tru-Trac
