Cummins goes to 1075 lb-ft

[KCJackson1]

Announced today (December 1 2020), the Ram 3500 with the HO Cummins has increased it torque output from 1000 lb-ft to 1075 lb-ft, besting Ford by 25. The gooseneck tow rating has increased in turn by a full ton from 35,100 pounds to 37,100. Cummins achieved the extra torque with increased boost pressure and fuel flow rate, and Ram made changes to the rear frame and rear axle crossmember to support the extra tow weight.

1075...

I know Ford will respond with 1100, but I hope that's the end of this. The brakes are not getting any bigger to stop these medium-duty loads.

Well, now if they would just install them in the 2500, like ford does with theirs in the F250...

Ford only has one version of its 6.7 PSD for pickups, they don't short the 3/4 ton owners.

But they have 2 sizes of rear axles. Makes you wonder how the small axle holds up if ran at 1 ton loads.

The axle size difference is more about loading than power handling, you wouldn't be putting the heavier loading on the 3/4-ton axle that you would on the 1-ton.

Wish they’d put a 5500 rated axle in the 3500 pick up.

Guys....I’m not the sharpest tool in the shed, and don’t want to come across as Negative Nancy. I’m glad Cummins is on top again. Additionally..... @Wiredawg and I have talked in the past, and we’re both left scratching our heads as to how the axle ratings can still not be exceeded with some of the advertised trailer weights.

I’m going to post both my empty truck weight and a recent weigh ticket of a run I performed.

Keep in mind my truck has a 16,500 lb GVWR and a 7,000 lb FAWR and a 12,000 lb RAWR.


Short of a strategically distributed tri axle trailer....I just don’t see how all of this increase in tow ratings can be usefully utilized in a 3500 DRW pickup with the axle ratings and tire ratings they currently have.....

Wish they’d put a 5500 rated axle in the 3500 pick up.

Wish they’d put the 1075 torque CTD in the 4500’s and 5500’s

But....that's how Ram does it

The max tow option includes bigger axles and bigger brakes, even the wheels are different

It’s both, and hard to overload the axle in a SRW configuration, but not as hard to hook to something heavy and damage the internals from sustained power.

But....that's how Ram does it

Nothing like good ol advertising!

Not too much different than the huge difference in 2500 and 3500 SRW GVWR’s despite a small difference in AWR’s, and often the same GCWR.

GCWR really is a mythical rating on a 3500 DRW , dang near impossible to actually obtain without overloading something else.

The max tow option includes bigger axles and bigger brakes, even the wheels are different

For 21? Where did you see that?

 

[TFucili]

The 12" axle, etc. started in '19 on the HO. I think the wheels are 8 on 200, same as Ferd(?)

I do think they need to move beyond the 17" wheel/tire package. At least offer the option of 19.5s.

The 12" axle is on the 2500 too, starting in 2019. The DRW, max tow or not, does get a different carrier/ring gear but the axle itself is still the same.

I don't see any other wheel option than steel or aluminum, both rated at 3000 lbs/wheel.

Yes a 19.5 option would be nice.

I went thru all the files on the body builder website and don't see anything that is different on a max tow, and you can get the "max tow" GCWR without getting the "max tow" package.

 

[TFucili]

They created a lot of confusion with the Max Tow name. Basically, it gives you the high GCWR options in one group, BUT it forces you into their fiver hitch.

If you just 4.10's you get the same GCWR but don't have to get their hitch.

All that's needed for the high GCWR is 4.10's, but yes the option group did create some confusion.

"GCWR really is a mythical rating on a 3500 DRW , dang near impossible to actually obtain without overloading something else."

To run full RAWR as I do the mythical 14k GVWR "is impossible" to obtain.

Don't even need to get that close to RAWR to exceed the 14K GVWR. I'm just over 14K with my truck camper and the RAW is right at 8500. Front is right at 5500.

 

[mpaulson]

I'm over the 14K GVWR all the time on holidays. I'm usually right around 5,400 on the front and 10,000 on the rear. So I use the axle ratings to the max and it puts me usually about 1,500 lbs over. Then I have 13.5K of RV behind the truck.
I would totally love a 4500 or 5500 pick up truck with 19.5" wheels, WITH the high output engine. If they didn't choke the 4500/5500's I'd consider buying one, but id rather have a pick up to drive the rest of the year while not holidayin.

 

[JR]

I like the inverter option. That would be a really handy deal.

No mention of transmission options either.

 

[GBBrown]

All fine and dandy...but did they upgrade the fuel pump for '21?
