2025 Ram 2500/3500 Heavy Duty Ready to Break Cover

I think the eventual goal may be to drive everyone to only buy the Cummins so they can effectively eliminate. The Cummins will end up as one of those "mandatory options" for $12k on every truck except a stripper Tradesman or CC.
If the 2027 emissions rules aren't changed the diesel option may be so expensive that it will kill diesels except for the very few that REALLY need one.

If RAM gets hard core on the controls for this new configuration eliminating any kind of tuning and the emissions reliability turns out to be even worse, we may look back on even the '19 through '24 fondly.

It may actually make something like the Cummins gas engine a good option, even with a GPF.

I wonder what percentage of Ford's HD sales are the 7.3 gasser?
 
If I am understanding the situation, all of the 2500 / 3500s have the same 8 speed transmission.

1sh gear a granny gear.

Routine use is 2 - 8.

The transmission has dual PTOs ( one on each side), so adding a hydraulic winch should be easy and not that expensive.

I am more used to electric motor based winch setups, but hydraulic winch is amazing.

I could be wrong, but this is my understanding.
This is incorrect. The new 8 speed paired with the Cummins is built by ZF, and based around the ZF 8 speed on the Hemi, but it's not the same transmission. It's much heavier-duty. The "standard" Hemi transmission (meaning not on CC trucks) doesn't have PTO.
 
Maybe this was posted elsewhere, but it looks like the gearset ratios published for the Powerline have been altered by the Ram version:

While much of the focus has been on Ram’s updated Heavy Duty pickup truck lineup, the brand has also introduced the all-new 2025 Ram 3500, 4500, and 5500 Chassis Cab trucks. These hard-working vehicles combine cutting-edge innovation, rugged durability, and top-tier capability. Designed for the toughest jobs, the updated Chassis Cab lineup now features upgraded powertrains, improved upfitter-friendly designs, and advanced technology, solidifying their place as the go-to choice for demanding tasks.

Thanks for that correction and clarity.

It is no wonder that consumers are confused when it comes to what is coming on their trucks.

I could have imagined that the shift points and gearing might be slightly different, but PTO or not, on the same otherwise ram 2500 or 3500 truck is just trying to make customers unhappy.

Shouldn't be that confusing. Gas engines have a ZF 8HP75 transmission and diesel engines have a 8AP1075.

It's one less automatic transmission offering on the HD pickups from 13-24.

Why is that going to make customers unhappy?

I can't recall the last time that the gas and diesel engines ran the same transmission in the HD Pickup.

I think the Hemi and CTD axle ratios are swapped, they don't match the published towing guides.

Hemi C&C 3500 lists 4.10's and the Cummins C&C 3500 lists 3.42's.

In the videos, they really talk to the PTO as a feature as if it is on all of the HDs. Reality is very different.

If the transmission is substantially different strength wise for a 2500 or 3500, from the gas to the diesel, then the reliability experiences of one mean nothing to the other.

I'll have to rewatch the videos but I recall the PTO discussion being centered around the new ZF 8AP1075 that is only mated to the 6.7.

If the transmission is substantially different strength wise for a 2500 or 3500, from the gas to the diesel, then the reliability experiences of one mean nothing to the other.

Which is nothing new, the gas transmission has always been weaker than the diesel transmission... but the power output is also different so even if the transmissions were identical you can't compare reliability when the diesel makes over 2x the torque.
 
Newer could understand the manufacturer's obsession with fake air scoops.
Agreed. I've got the fake hood scoop on mine, and while I do think it looks "cool" I'd rather it either be real or not there.
 
Good video on the new 2025 6.7 changes. I love my MY23 Rebel HD 6.7 but I must admit, I do like the changes made, (as well as the new ZF 8 speed!). Easier to change the filters.

Helical gears driving the cam and fuel pump for quieter operation.
ECU is able to be flashed OTA now. (Wow!)
CP8 HPFP, 2200 bar, or 30,000 PSI.
Cast Aluminum intake manifold for improved air flow. (No grid heater.)
Glow plugs
Primary and Secondary Fuel Filters accessible from top down (grid heater intake manifold probably made room for that)
Top Side oil filter for easier access; now a cartridge filter
New combo DOC/EGR cooler combo
New Holset Turbo

It may actually make something like the Cummins gas engine a good option, even with a GPF.
GPFs are actually pretty trouble-free, as gas engine generate plenty of waste heat to cook them clean.

They have a number of extra sensors and such increasing complexity. My understanding is the unit itself is considerably more reliable but doesn't live well on higher mileage engines that start using oil.

Agree.

Notice the 2 different 8AP for the CC Hemi/Diesel and that the 8th gear 2nd OD is different and the Diesel has a much deeper reverse gear.
 

Spent some time with the new trucks today, look great in person.

Thanks - look great.

Would be neat if they could offer a megacab in that 5500.

I like the cab without the sun roof taking up space inside, they are too short inside already.

So I don't disagree, but it depends on the situation that a person is in.

I would like to buy a ram hd truck 4wd and really use the full features. The PTO would be very handy.

Due to my planned use case and location, diesel cummins is not really viable, no matter how much I like it.

RAM might separate the details of feature set concept for gas vs diesel by slicing and dicing, but if a person watches a video of the head of ram talk about the "2500s and 3500s" features, I would not expect to loose a feature in a 2500 / 3500 just because of being forced into a lesser engine capability / Hemi. Either way, it is approaching a 80 - 100K event, so we aren't talking about splitting nickels.
