I've got a 8.8 in the back of my YJ, it's on the list of best mods, I grabbed one w/ matching 4.10s and LSD and it's been working great and getting me down allot of trails I just shouldn't be on w/ 34's and it's handling all the abuse I can toss at it. This winter I'll be tightening up the LSD even though it really doesn't need it, and going 4.88's, I'll also be shving the center for better ground clearence.
