Re: Rear diff gear change and LSD?
4.10's work great with my 4x4 running same size tires as you. I have a stock limited slip which was rebuilt when I did the gear change and it works fine for most situations I will ever be in. A little trick with an LSD, if it starts to slip, tap your brake or set the park brake one or two clicks. That will help to engage the LSD and get you moving in many cases.
