2500 - Do I want the 3.73 or 4.10?

[Andrew Austin]

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 tow a just under 7,000lb Jayco with 3.73 an it does good. I drive 74 miles a day for work an the mileage ain't bad. I even drag the camper off road to hunt camp an not much problem when the clay is wet.
I live in N W. Ga an its hilly but if your drivin mountains you "might" want the lower gear.

4.10 all day long. like was said no difference in mpg but you will feel better driving.

+ one....go for 4.10's

If the truck has everything you want to with either or.

If you have time and do not have a must have list get the 4.10

 

[Andrew Austin]

Thank you, all, for your responses. Looks like the 4.10 wins!

4.10 every time

I can not think of a post where some one had 4.10's and wished they would have gotten 3.73's but I have seen it the other way around more than once.

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.

I started out with 4:10's in my trucks. Then I bought one with 3:73.
After that one, I am back to 4:10's.

I have a 2021 2500 Big Horn Level 2 crew cab off-road with 4:10s. I avg about 13mpg normal everday driving. I tow a 32ft travel trailer so I opted for 4:10s...for what I use my truck for 4:10s made sense. Plus as others stated and I would have to agree the mpg is probably unnoticeable. Let's face it....ppl do not buy heavy duties IMO and really expect to get great mpg

I went with 3.73’s. I tow infrequently but found this ratio to be favorable for my use case of driving to (tent) camp sites.

 

[Firebird]

Having owned both, do not hesitate, get the 4.10's

 

[WoodGuy]

The RPM difference between 3.73 and 4.10's at 70mph is about 175. Miniscule mpg difference one way or the other. I went 4.10 myself when I ordered mine and she does a nice job of towing a 10-12k dump trailer

I had a 2019 2500 with the 4.10. I was certain I wanted 4.10 going in after having 2 Ford 6.2's, one with 3.73 the next with 4.30. The 4.30 was well worth it in the ford with their 6 speed. But after driving the Ram 8spd and 4.10, I felt for my driving and needs it was lower than I needed. 1st gear with the stock tires was so low. If I order a new Ram, it will have the 3.73. Most of my driving is unloaded around town, and when I tow it is 10k and under.

You also have to consider what tranny you are using... with the 8 speed I would go with 3.73... 6 speed then 4.10...

 

[Andy Morrison]

I have a 2020 Tradesman with the 6.4 and 4:10’s. Getting 14.5 around town and 17 at 80. The 8 speed tranny is awesome. It is a beast.

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....!

I hate driving a 4.10 the 3.73 just feels better everyday driving and can handle your trailer. I notice it because I drive them all the time different ones. Some people prefer it. It’s definitely more heavy duty. Ide suggest driving one of each. Other than that either can handle it.
