Do not see the pictures.
Sorry I had to edit some of the pictures and go back to 2006 to figure out how to do that on this forum. Nothing special just a work truck that’s going to pull a trailer every day.

Thanks for the kind words guys. I’ll get a better picture tomorrow now that I know how to edit.
With the Jake break off and driving down the highway when letting off the fuel the transmission seems to make a roaring sound. Other than that so far I like the truck.
 
I’ve looked everywhere I think they were too busy shooting these things out the door.
A good friend of mine has a 19 and the sticker that’s pictured above has all of the information about horsepower.
 
There will be 2 stickers like always. Possible but doubtful, the pump info will be on the valve cover sticker, but the one I asked to see has been on the hood near the right side/ hinge. That seemed to have some strange info on it, and I asked to see that.
I was looking at some trucks online, and some that I saw were ‘20’s and were still enroute so I couldn’t see the window stickers on those.
 
comrade - bought a 2018 2500 g56. at 6k the clutch went out. got it back few days later, broke again. clutch out. then 30 days at dealer. im a contractor and same as you no truck no work ( or limited work ) thankfully i have a 2001 2500 that barley works anymore, and a 1995 subaru wagon ( that has never broke in 296,000 ) i will say ram did step up and make my january truck payment, which i find honorable. i find the parts availability / shortage somewhat concerning these days, but everyone will blame it on the china flu. merry christmas. cheers! :)

You can download Cummins Quickserve App onto your Smartphone, plug in your Engine Serial Number (ESN), and you will get all the info about your engine you need to know.

The 2021 Cp3 being retrofit may be unlikely since the timing gear cover and pump gear are different

That's why I think they are spinning that 2021 CP3 faster than a 2018 CP3... In it's form up to 2018 it was already under utilized so bumping it up a few rpm wise is a no brainer. I doubt Bosch made a bored or stroked pump only for FCA Cummins.. Bosch just said to FCA "spin it faster for wanted results".

But they don’t need to. Countless people are pushing their stock 03-18 CP3’s harder than needed for the 21’s power output.

I’d be more surprised if anything was different gear train wise over an 18 than if not. I wouldn’t be surprised if there where some internal mods to help longevity with sustained higher pressure, but even that’s not a guarantee. If you look at the 6.7 vs 5.9 rail pressure maps the 5.9’s ran a higher average pressure despite the 6.7’s higher peak pressure.

The timing gear and cover are different from a CP4 for sure, but I doubt from a 2018 CP3.
