Anybody actually like there 3.73 towing 8-10,000 pounds

Ita not that I'm 100% unhappy with my 6.4 and 4.10 rear. My biggest issue is towing heavy in the mountains when you need to start from a dead stop. The 3.23 1st gear is a bit too high to get the load moving quickly. These Hemi trucks need to rev to make torque and hp, but with such a high 1st gear it's hard to do.

So by regearing to something lower, you are ultimately lowering your overall 1st gear as well. Yes, it remains a 3.23, but running through a lower rear gear, it feels much lower and more capable. Just my thoughts on it all after towing heavy a few times.

Do some 4.88's. You will be able to pull house's down. I think fca is just bound to gas milage. Thats why things are the way they are. A 6.4 hemi is very Capable but tied down by trans and gearing

With my 6.4 hemi towing 10,000+ and stock 3.73’s i was not happy. Went to 4.88’s for a BIG improvement. I have 35” tires. I wish i went to 5.13’s but 4.88’s perform exceptionally well compared to 3.73’s. 5.13’s will give me an extra 100rpm across the board basically

If i was to keep the stock 33” tires i would STILL got to 4.88’s if i was towing often.

Do you guys use tow/haul mode in the mountains. I pull 7K w/ 6.4 gas w/3.73 rear in hilly country & have no trouble at all using TH. I drive in the flats 80% of the time and it will run in eco and get 16mph if I keep it under 65 w/ tow/haul off.

Yes, I use tow/haul. The big difference is elevation. I live at 6400’ and always camp higher. This NA Hemi or any NA powerplant just can’t breathe properly. This truck is my daily driver and around town it is what it is (no real complaints). We try to camp a lot so the only time this truck is used like a truck is when we pull the TT. I was telling the OP if it was me I would get more truck to pull heavy in real mountains. I’m sure it’s good in the hills.

I live just a bit south of you and agree that the high altitude really takes a toll on our trucks horsepower. Going back home to Tennessee and driving in the hills/mountains there is night and day difference to the Rockies. Back home I can actually feel how much power this truck has and I definitely loose 10-20% in the Springs due to altitude. Hunting high is worse yet.

When I had my 2016 2500 6.4L Hemi with the 4.10 I love it but I had the 5.7L Hemi with the 3.73 gears it was a dog I did not like it.

With my 2018 CCLB 2500 6.4 in SE Montana I toe in 4th gear. In the hills. When on the flat I tow in 5th. I also found for me anyway 58-62 mph is my sweet spot. I came from a 6.7 Cummins to the 6.4. Big learning curve. With my TT and Pickup total weight is 14300. Lbs

The pros say we lose about 3% HP for every 1000' in elevation change. That puts most of Colorado at a 15%-20% lose. I know when I'm at sea level its easy to lite up the tires. I also have to dial back the PC.

My TT is 7,000lbs. loaded for camping. I’ve been up and down every major pass in CO with this 2500 6.4L 3:73 truck. I towed the same with my 2014 F150 Ecoboost 3:73. The turbo can’t be beat. This truck is obviously more stable which was the main reason I bought it, but the Ecoboost crushed this thing going up the hills. I’m all the way in the peddle (30-35mph) and holding up traffic where the Ecoboost was 45mpg with plenty of peddle left. I would definitely get more if you can.

Now that's laughable ...

I have a 2014 w/ 3.73 and tow a 9500lb (loaded) 5th wheel and can say that I am pretty pleased with the setup. I probably tow 6 to 10 times per year in and around the East Tennessee area (some fairly mountainous places). I was towing a 7k travel trailer before I purchased the 5th wheel and actually found that I feel more safe/secure/in control with the heavier fifth wheel FWIW. If I had it to do over I would order the truck w/ 4.10 but for the amount of towing that I do it does not warrant the purchase price of regearing to me (at this time).

the 6.4 vs the 3.5 eco at high elevations is not a fair comparison. The boosted motor does not end up feeling the effects of elevation as dramatically as it is feed the same amount of air to the cylinder as it is a sea level where a NA (normally aspirated) engine is not. It's one reasons diesels are preferred for heavy towing in today's day and age as they are all force feed i.e. boosted and do not feel the effects of elevation. Gearing whether trany or axle will not change this, on any NA engine as the engine is atmospherically starved.

I laughed at the part where you state your ford 1/2 truck is more stable pulling 7,000 lbs verses the 3/4 ram..Good luck with that turbo down the road.

I guess obvious, isn’t so obvious. If you slow down and read the post again I think you will see we actually have the same opinion. Good luck with that.

 

[Mountaineer83]

My dad has an EcoBoost and it doesnt even know their 28' TT is back there. Granted it's only 6000ish lbs, but like you mentioned, the stability just isn't there like my Ram 2500.

My Tundra towed power wise as well as my 6.4, but now where near as stable.

It is how you have it worded..I see it now..

I picked up a 2018 2500 Laramie last year with 3.73's and the 6.4. We have a 33 foot travel trailer that comes in about 9500lb unloaded. Took that trailer to Maryland from NE Pa. Went up and down the turnpike at 75mph with no problem. The truck wasn't working hard at all to do it. My 2005 2500 with the 5.7 would not have been able to come close to that.
I don't think I'd spend the money to re-gear with that kind of performance then have to live with the reduced gas mileage the rest of the time.

Like 68powerwagon said " pulls like a freight train". Just sayin...
