12-13 is what you will get I will not guess I am telling you. Your truck will not want to turn them things with 3.73's. I have TSL's and could not imagine boggers with 3.73's. I hate it with the TSL's. I get 13 consistenly and I baby the gas big time. If you want boggers. I would think you don't care about road noise, smooth driving, or any on road features. But get some new gears or a lighter less aggressive tire if this is not a primarily off road vehicle. Boggers great for the off road but even for off road you should go to at least 4.10 gears. I am going to 4.56 gears that is truly how hard of a time the truck has to turn these tires. And you can forget about OD the truck will not stay in OD it will only shift in and out.
