2500 - Do I want the 3.73 or 4.10?

[OC455]

4.10's if ordering. As was mentioned above, if the right truck coms along....3.73 are ok. 4.10's will get you a higher towing capacity in most cases.

Hi,
I am looking at a new 2500 this year (gas) and I am wondering whether the 3.73 or 4.10 is best for me. I tow an 8000 lb (loaded) camper in the summer as well as a 3000 lb boat. I am thinking the 3.73 is all I need, but if there is not much difference in gas mileage, then maybe the 4.10 is best - then I can get a heavier travel trailer potentially. I will use the truck as a daily driver the rest of the time. My commute to work is pretty short, so I am wondering if the 4.10 is worth the extra gas.
Any thoughts?
Thanks,
Andrew

I am running a 2017 3500 crew cab short box 6.4 hemi 6 speed auto
My hitchhiker fifth wheel is 14000 lbs
I changed my gears to 456 and am running a slightly taller tire than stock(285-65-20)(my stock gears were 3.73)
You can get a 3500 chassis truck with 444 gears from the factory so the 456 with a slightly taller tire is very close
The truck pulls every grade with ease
Tow Haul mode works much better on the downgrades with this set up as well
Truck never gets hot even when towing at 100 plus degrees outside
empty is 2000 rpm at 71 mph
hwy empty mileage dropped about 1.5 mpg
city empty mileage went up about 1 mpg
just my opinion better gears equal less wear and tear on the rest of the truck
components= less cost on repairs down the road

If you are serious about towing, go for the Cummins HO Turbo Diesel. Real trucks have a diesel engine under the hood, especially trucks that tow regularly.

Flame retardant suit on....!

Hahaha.... there's always that one guy hoping to stir the **** pot...lol

I have 4.10s and am very happy with the truck. I put 35” Toyo AT3s on it and other than riding better than the stock Transforce tires I’ve noticed no difference in power.

If you plan on going to a heavier trailer some day you will be much happier with the 4:10's, they pull so much easier

This is what I get on my 2500 tradesman with 4.10 ->

 

[Jeff Ward]

I don't think the difference will be very noticeable from either a MPG or performance standpoint. I sure wish I had the 4.10s (or more like 4.56s) on my 2014 but your newer 8spd tranny is a HUGE (let me repeat that, HUGE) difference. In your situation if I could choose I'd probably go for the 4.10s but if the right truck came along with 3.73s I wouldn't hesitate.

mtofell is correct. The new 8 speed is a game changer. I just bought a 2019 2500 gas last year with the 3.73s and wouldn't hesitate to pull the trigger on one again. 1st and 2nd gear ain't no joke on this truck

 

[redman4455]

3.73 will fit the bill if you plan on staying stock and you find a truck at a nice price point. I wouldn't hesitate on purchasing considering only the ratio anyway. However, if you think you'll end up with a lift or bigger tires somewhere down the road I'd go 4.10. If cost makes no difference, I'd go 4.10 simply for the upsize potential but that's if you're willing to sacrifice a decent deal for that option. If you're chasing MPG, just forget it, a 3.73 or 4.10 will get you similar results and should rarely impact your decision parameter. These trucks suck fuel, they always will. Best way to improve MPG is to just lay off the throttle when you don't need it, just cruise it baby.

Lol, I'll bite like a sucker. Got a hemi 2500. Don't tow a monster but need the payload and the hemi 2500 has a respectable 2900+ pounds in my trim. Would have gone 3500 but registration costs where I'm at are insane. Tried voting the jerks out but that doesn't seem to work apparently with Dominion screwing all of us. Also, don't want the headache of a diesel. I know V8's well enough to do my own maintenance to a certain point and that's what I'm comfortable with.

But yeah, the Cummins is a beast and drives so nice. Almost got one but in the end decided the hemi did everything I needed without the added costs of a diesel... (Where I'm from anyway).

The problem with the 2500 and the Cummins is the payload. If you go with the Cummins, I would upgrade to the 3500.

the other problem with the cummins is the 6 speed, only 370 Hp in the 2500 configuration.

I ordered my truck with 4.10s and I’m in the same situation you are. 7,500lb camper and 5,000 dump trailer. Truck is not my DD and I live in Appalachia. 4.10 seemed like a no brainer. I’ll let you know for sure how I feel if my truck ever shows up.

even with the 6 spd and only 370 hp the CTD will out tow the 6.4l Hemi without breaking a sweat. The CTD makes more torque just off ide than the Hemi does maxed out, torque is what tows a trailer.

Yes the torque is where it’s at. Look at semi trucks a lot of them are around 400hp but the torque is anywhere from 1400 to 2000 ft lbs. that’s what gets it moving.

A 2500 CTD is 850 ft/lbs with a GCVWR of around 25K lbs where are a semi has a GCVWR over 100K lbs.

It's interesting that the chassis cab with the 6.4 Hemi are derated to 370 hp and the same 429 ft/lbs of torque

understandable, but my 8 speed hemi beats a 2017 6 speed SO cummins off the line with ease and up top. ive ran against one of my employees trucks a few times. I just hate that Ram is the only truck with SO and HO. if I ever buy diesel its the powerstroke for me.

Hook a 10K lbs trailer behind both trucks and see who looking at taillights, especially when it comes to the mountains.

Fair enough haha!
