No. 3.73's. Hasn't disappointed me yet. Very happy with it.

 

 

great to hear. Mine is 3.73 as well. Coming from a 6.7, there is definetely a noticeable difference in power. However, for my uses, I have not found anything I cannot do now that I could do before.

 

Went from a 2006 5.4...

To a 2018 6.2

 

Thank you. Considered the colors for a long time before submitting the order, very pleased with the outcome.

 

I like the combo in my dually but do wonder if I'd get a bit better mileage with the 4.30's. I'm often hauling right at the 14,000# GVWR. How about you? With our huge TC on long road trips, we get between 8-9 mpg. Most of that is at the speed limit of 65 mph. Pretty sure I could get close to 10 if I insisted on only doing 55 but that really ticks people off up here in the summertime.

 

How about a gas Super Cab dually?

 

I'm just under 13k with my Lance and currently on a 4000 mile camping trip. So far I'm getting 9.9 mpg with 4.30 gearing. Truck has 3200 miles.

 

I get between 9 and 10 carrying my TC. About 8.5 if I add the boat in behind. I think there is very little difference in terms of fuel mileage. Yours probably downshifts a little later than mine on hills and gets up to speed quicker. Neither of which I find to be an issue. I got the 3.73 because I thought it would benefit mileage and I carry weight, I don't pull it. My heaviest trailer is only 8000 lbs. After owning it for a year and reading others experiences with the 4.30, gearing seems to be a moot point as far as fuel mileage goes. There is no big measurable difference as far as I can see. The 4.30 likely performs better in acceleration but I have been very happy with my 3.73. I would get another without thinking about it but I would also consider the 4.30 due to the minimal mileage difference. That being said, if it might save me 0.4 mpg I would lean towards the 3.73 because gas is so expensive and not getting cheaper. Got to save money where I can. The trucks have tons of power. I still don't know how well it accelerates because I don't drive it hard. I think the gearing is more of a personal preference based on driving habits rather than a clear choice which can be proven through statistics. The waters are too muddy one way or the other.

 

Hey RZAR, what's the payload on that rig? Has to be massive. Looks great.

 

Thanks. Payload is 6519 lbs.

 

17' 250. 6.2, 4:30's.

 

CCLB / 4.30 / XL / Sync3 / Camper package Custom ordered to get exactly what I wanted; I was willing to be very picky and nobody had anything even close to what I was looking for.


I might win for biggest leap in the upgrade from my old ride. Still have the square body, hope to give it the the full big block cruise night treatment one of these days. People cringe when they ask about the mileage on my SD, but then I tell them it was still a 20% improvement, and 50% better on the highway!

Love my truck. It's really incredible how far things have come, even in the last 10 years or so, not to mention 30. Although going from a 32 year old single cab to a CCLB was like going from a go cart to an aircraft carrier, I can't think of anything I'd rather do in the old truck these days. Maybe burnouts.

 

Here are some pics of our "old" 2017 F350 6.2 3.73 CCSb XLT Prem in action earlier this year.

Enjoy!
