The other thing to consider is that you may want to change your bearings while you are there. A lot of offroad shops like mine will add this into the price of setting up ring and pinions because it is a logical thing to do. Most places that set up a lot of ring and pinions won'r even give you the option of not doing it. Price will vary around the US and also depends on reputation of the shop. We are know for doing it and are usually around $500 per axle and $600 per axle if we are changing the bearings. Going labor rate in our area is $65/hr so this also plays into it. There is a shop in our area that is nationally know in the racing world and he charges $2500 per axle to set up ring and pinion.
