I really hate to enter in to this spirited conversation mid stream , but I am in desperate need of advice. I HAD a 2013 F-350 6.7psd 3.73 rear that towed my 15000# fifth wheel. It has been wrecked and now I am looking @ a 2016 F-350 or F-450 . My question is if I opt for 4.30 gears what will I gain /sacrifice over my 2013 in terms of fuel milage, top end etc.etc. I understand that I will have a better bottom end but at which cost.
I would greatly appreciate any advice or feed back that can be offered
When talking about diesel 3.73 gears are great because of the rpm operating range, 4.30 gears would kill your top end.
We've been discussing 4.30 gears in a gas motor not a diesel, gas motors make most of their power in the higher rpms unlike the diesel so the 4.30 gears are better suited for gas motors that are pulling loads.
