Well i can get a good deal on a set of 4.88 gears with the limited slip carrier for my rear dana 35. Do you think these would be good with the 31" tires i am running? Eventually i would like to upgrade to 33's but that is down the road. I know that i will have to get a set for the front but will these help or hurt me offroad? The xj might see just a very little bit of road time but most will be offroad.

Thanks,
Ben
