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, ...

The lower gear 4.30:1 be better for towing any load.
This will be most noticeable on starting off and hills.
The 3.73:1 will give slightly better MPG when unloaded.
Just to compare my E450 based Class C is a 4.63:1.
Gear are your friend when towing.
