Choice of rear axle on 2016 F350
Hi everyone. We're ordering a new F350 (4x4 CC LB Diesel) and are trying to decide between the 3.73 and 4.30 rear axles. Presumably the 3.73 will have significantly better MPG, both empty and towing, ...

I'm going a little different on my preference of gears. I currently have 3.42 and with the torque of today's diesels have zero issues getting took off. Matter of fact I have had my traction control kick in a few times taking off on wet black top on slight inclines pulling my 20,000 rig. Running down the interstate I just lock it in 5th and roll on at around 1800 rpm which is close to 70 mph. When running on the two lane back roads I lock it in 4th. I have zero power issues with my high gears. If I had a choice in gears I would go with the 3.73 if I towed full time but my truck is a mixed use truck and when unloaded or towing the boat the high gear is great. My fuel mileage is great for an 8,000# truck and you can't here the engine running down the road because it is basically idling. JMO of course.
