Robusmcs13 is on a distinguished road

depending on what year you have, the newer trans has a very low ratio, I have an 08 2wd 4.7 with 4.10s and its perfect with the stock 17's with 265/60/17(about 30.5 inches) at 70 mph I'm running right below 2000 rpm.
I would have went with 4.56's cuz i will be putting on 35" tires but I read somewhere that some people have issues with harmonic resonance and such due to the 2wd having a longer drive shaft. In my opinion its well worth the money just have a reputable shop with lots of experience install them(not a dealership they dont know how to measure aftermarket).
I got my truetrac and gears from Nick at and I couldnt be happier, Nick helped me alot and really knows his stuff.
Hope this helps, everyone has something to say but first hand experience is always the best
