Difference between 4.30 & 3.55 gears
My 2011 F-350 has a 3.55 geared rear end. The new 2017 F-450 only comes with a 4.30 geared rear end. Basically the same engine (6.7 turbo diesel). Does that mean better or worse fuel consumption...

On a side note, I've had both. My 2011 F450 had the 4.30 rear with 17" wheels. My 2015 F350 has the 3.55 with 20" wheels.
On the surface, that sounds like the two trucks are world's apart. As crazy as it sounds, I prefer the 3.55, even for large heavy loads. The 4.30 was complete overkill. But we do virtually no mountain travel.
May I inquire what you're pulling?
