Factory 4.10's in the diesel?

[bentrod]

That is what I have and heard too, unless some sort of change recently.

And even with the camper, I am back at around 23 mpg highway (65 cruising speed).

410s installed. The 37s now rides like 33s. No longer feels like I'm cheating myself out of the diesel power by not regearing.

Guys and gals, I had 3.73's in my Dually and pulled anything I wanted. I would only go with 4.10's if I was pulling max/Heavy constantly. Heck the chassis cabs have a 4.88 option and I wouldn't do that unless it stayed loaded....

what were you getting MPG wise before?

I think....if you order a diesel you do not get 4.10's unless it is a Rubicon then it comes with them. Try building one online and see what it gives you for gears.

cannot get 4.10s w the diesel. 3.73 only

Yes, someone else mentioned that after I posted, after looking again I saw they were correct.

More than warranty. It is not like getting a car built in the 1960's or 1970's when everything was non software driven and analog where you could get a buddy at the factory to walk a special option on the vehicle.

Putting 4.10's on a Diesel would also cascade down the chain on the PCM programming if not other things. The dealers cannot over ride their order system and just put things on that are not allowed due to engineering constraints.

I'm wondering how long it will be before tire and gears changes are illegal since all of this stuff is certified by the EPA signoff?

Ex brother in law worked for Ford back in the late 60's early 70's where they built the Mustang. He built his own '70 Boss 302 Mustang on the line. Walked down the line with it. Every performance part Ford had at that time was on that car.

I dont know what truck that was in bud it’s likely double the torque and 50-75% more hp. Not comparable

I think the mixed up the 4:1 transfer case vs alxe ratio.
