I use to work at the plant where the engines are made and the pistons are different as well as the heads. Many components are different between the standard and high output. Cranks camshafts as well as others. We always had to swap parts when we did different standards or high output. I also worked on the machining side for the block. The high output puts would have 1 freeze plug left out on the side and standards would have them all in place once they reached ready for assembly. CGI issues are that they have lots of porosity that’s hard to catch compared to original cast irons.

Admit it folks, that's the vid tons of us were waiting for... Thanks Alex 👍🏻

I own both Cummins the H.O. And standard. Let me tell you the H.O. Will lug up the hills just about idle. The standard will downshift until it redlines to make it up the hills. Go high output.

Great Video!! Always learn a lot here!

Love your videos. Very insightful. How would you spec a 2024 HD Megacab for overlanding and Towing purposes?

I’m on my 3rd , 5th gen ram . My latest is a 22 Mega dually H.O and i am impressed by the power compared to the S.O

Great info Alex, thanks!

I order a 3500 SRW 4x4 Larmie back in 2018. Standard output engine with 48RFE. At 25K miles I get about 16 mpg unloaded. It was extremely hard to decide HO or standard (cool factor). After considering $$ and impact to tow #'s I went standard, and it works fine for my trivial towing needs. Great info on the differences. Thank you. I may not be "HO-Cool" but I am cool enough 🙂

Great video

Went from a ‘18 1 ton dually SO (which after a while I deleted) to my most recent ‘22 1 ton dually HO and man the difference is noticeable. Pulls way better than my deleted 18. Pulls a 20k lb backhoe with ease.

Well explained presentation.

I’ve been waiting for your approval on this

I agree the CP4 pumps sucks, fortunately ram did recall the pump. I’m in line now to get mine replaced

Have you done a video comparing the 68RFE to the Aisin? Currently shopping for trucks and still unsure about that 68RFE. Lotta negative hype out there! Thanks.

I am extremely happy with our 2020 Ram 3500 SWR HO for towing our 2021 Montana 3231CK! With a match made on the road, it's clear that this truck is well-suited for our needs. The 9.8 MPG on long trips from SC to UT and back is not that impressive, was expecting around 2MPG. 865 days after purchase I am getting my CP4 pump replaced under warranty. Not sure if this will help with MPG I did ask and the tech didn’t seem to think it would. Many thanks Alex for your videos.

When did the new 6.7 Cummings engine come out, like I’m talking the one with the 16-2 compression ratio

Im looking to buy a 2019 how can i tell the difference and do all h.o. Cummins come with the aisin

I'm wondering what the milage between overhaul would be, a semi will last about 500,000-600,000 miles between inframe (not pulling the motor out) overhauls.

Thanks for this info. Do you know if they have made any changes to the Aisin transmission through out the years? (19-22)

How to tune the SO to get the HO power ratings?! 🎉

Considering the power levels of the mechanical 5.9L engines. And how pleased people were with the power. If a demonstration of the 4cyl B motor. With the VGT turbo and an 8-speed ZF medium duty transmission. Running the 3.42 for 33" tires, 3.73 for 35's. A 4.4L would be plenty of power! And most important with $7 or more a Gallon fuel prices. Extremely economical and practical!. We have a 2018 Ram 2500 4wd 3.42 ratio with the 6.7L standard output. That truck is a beast! We also have a 2016 Ram 1500 4wd 3.92 ratio with the 3L. But both trucks pull the same trailers rather nicely. The 3L gets 17mpg @ 55mph, whole the 6.7L gets 13mpg @ 55mph. Pulling the exact same trailer. Because of the ZF 8-speed, the 3L is the one to drive in snow and ice conditions. The 6.7L has just way to much power and throttle sensitivity with the taller axle ratio and only 6 speeds. If we could buy a Ram 3500 with the 4cyl Cummins B series, ZF 8-speed, 3.42 axle ratio. Highway fuel economy would be 36mpg at 62mph/100kph. And would still be a beast!

Can you do a video of the HO Ram vs HO Ford please

I just ordered one of these. I run hotshot across the country so I decided this one was the best for me. High output with the tradesmen model 3500….

I own a 2022 3500 dully with the standard engine and transmission, my brother in-law bought a 2023 with the HO, now he's driven my truck, I haven't his. He has determined his truck is as strong as mine, we do the exact same type of work and we haul the same things, now I don't know if it's a factor that my truck is broken in and his is rather new or what, my truck is also heavier being 4x4

Alex, question for you. We are going full time RV living soon and wanted to know your opinion as to how much towing is the amount that crosses the line where you need a HO RAM 3500 as opposed to the Standard Output Cummins? Is it a matter of terrain? Percentage of miles towing vs. non-tow driving? GVW of 5th wheel will be in 18k lb. (8,200 kg) range.

Dude I love your videos,, i feel like the worse that happened to Diesel in general is the DEF system

I have a 2022 HO with 4:10 gears. It is used for hauling only. I run from MI to TX every month to pick up a new gooseneck and come back with 18 to 22k pounds behhind me on average. This truck has more power than it needs, or it doesn't need the 4:10s. Didn't think I would ever say that, Truck doesn't like being shoved to the floor, there is really no need. Haven't found an entrance ramp that I couldn't do 70 by the time I merge when loaded. My 2015 had HO, 4:10 gears better al a round set up and the air ride worked much better. The 2022 does get better mileage for some reason. Have only made 3 trips in it. There is nothing like a new truck!

Sound like regulator out put power is better for boat towing, SRW is better DRW for not towing ALL TIME. I saw one in the shopping packing lot, it SRW big horn, dark red color, and it's so nice. This truck town 35 feet boat easily. Look nice.

Thanks for the video, I thought I would learn more but there is a lot of misinformation in your video. After having six different RAM 2500 trucks for my Marine Transport business since 2015 & logging almost 1,000,000 miles since... I bought a 2021 RAM MegaCab Limited HO Dually 4.10 truck and learned the hard way how poor the MPGs were with the HO compared to the SO of my previous 2500s. The funny thing about towing boats is that the MAX weight ratings are calculated by towing an actual WEIGHT on a Flatbed trailer for testing, tuning and safety control by the Manufacturer. What they do not do is actually haul something like a large boat weighing 15,000# which falls far under the realm of the 30K+ max weight but what it does do is have very irregular airflow versus say a weight on a flatbed gooseneck. This lack of insight in tuning plays a role where the engine can demand more DEF to compensate for say, huge Headwinds when towing West across Wyoming towards Washington, than the tuning was ever programmed for... so then you get "DEF System See Dealer" messages and a limp mode to render your truck useless. Of course, the "Plug N Play" Techs are just as useless since they are not allowed to test your truck hauling a load, and when operating said truck at normal loads, never hits the window of operation so they could see what is actually happening... you get a reset and "Nothing Is Wrong Here" from the dealer and a bill for the service since it is not covered by warranty. SO... to shed some light on the real mechanical differences between the two trucks, SO & HO. It's the Pistons and tuning... nothing more. The Camshaft, Block, rods and crank are all the same. You might be surprised to know the turbo is the exact same part too... everything is done by tuning. What is truly different is the rear axle... so do not order the BANKS Diff cover for a 2021 Ram HO from anywhere other than SUMMIT Racing, as the earlier part numbers showed the wrong axle. The reason Summit has it right is because that is where I ordered it from, and they have now had a PowWow with BANKS to get the right part numbers in their system. Can an HO truck be made to achieve the fuel economy of the SO trucks...? YES!!! It Can, but be ready to break out the wallet for some serious cash. Just note, by this time... you are now going to spend an additional $3500-5500 on TOP of what it cost you to upgrade to the HO from an SO... JUST TO GET THE AISIN Transmission. For less money, you could do an ATS Allison Swap and still get 20+mpg!!! The BANKS MonsterRam is worth 2-3mpg across the board when installed with the heater grid delete. Add in the Ram Air box Banks calls a "Super Scoop" and the hard pipes to see 19-21mpg unladen and 10.5-12mpg while towing anything over 12K#. I have documented this and yes, saved some fuel along the way. Just doing the #JennyCraigMod is not enough. I have much of these changes shared on my channel as well as the subtle differences like how the EGR is affixed to the exhaust manifold on the newer HO trucks. Keep up the great videos!!

how do you adjust the hydraulic lifters?

I have a 2008 with the Ascin trans. So they have been around much longer than 2013.

Can you tell apart by looking at them? If so how? As im shopping around and i tow every day

Can a standard be converted to High Output?

In 2022 only truck you get ho option is 3500. I bought a 2022 3500 4x4 limited longhorn short bedega cab love thisctruck

Quick question,, what do u think about the baffle inside the intake ? Removing it or No ? Pros and cons ,, please thanks

Love having my G56 fourth gen. Do a little work to it if you know what I mean and put in a better clutch and you could be close to a high output with a stick shift best of both worlds.

will '23 colors have some cool like desert sand or od green? if not, white, black, silver, gray, blue, red ho hums then.

I just bought my 3500 single rear wheel with the HO engine and Aisin transmission it’s a very powerful engine, but it does drinks a lot of diesel

So they are both 6.7L engines. But for the high output the only difference is the Aisin transmisson which makes it high output ?? How can you tell the difference ?

Maybe different head gaskets to change the CR. That would be the easiest(cheapest) way to lower CR.

As soon as I saw the shorter connecting rods, I knew... I has guessed 17:1 just from apperance.

So what do you think mpg difference is while driving the same?

I've compared the piston part numbers between an SO and HO when they first released the CGI engine and they are different part numbers. It's pistons and tuning/boost. Nothing else. Same HPFP's.

How do you know if you have a HO vs standard?

What is difference in blue def and platinum blue def ? Besides cost?

Will you ever touch on delete kits ?

On Dec/2022 I bought a SRW Ram 3500 with the H.O. Cummins and the AISIN Transmission. Driving with a light foot I get between 13.8mpg - 15.3mpg actual efficiency. The computer always says it's higher 15.5 - 16.5mpg, but it's never correct. What MPG do you guys see with your H.O. Cummins & AISIN Transmission??? I've seen people reporting fairly high mpg with the Standard Output Cummins & 68RFE Transmission. But I'm curious about actual calculated (not computer) MPG for the H.O. & AISIN. Can anyone share your experience???

I think this is more a about show his hand then the actual truck .

80% of the owners will never use all of the torque of the standard output

Will the high output be as durable?

Music is really loud compared to your voice - have to keep going up down up down on the volume control :)

That is funny all that torture and from the owners I know 13 to 15 mpg . I'll keep my 765 ft pounds and 20mpg all day. The race to have the most sometimes is not very user efficient in this environment nor has it been for some time now.

Another difference is the ho has the aisin transmission st don't

I own the HO besides the clunky trans that truck will pull any hill with no issues

I don’t understand why the offer 2 versions who wants a lower power engine when buying a diesel truck? If buying a 3/4 might as well go Chevy or ford.

It's a shame ram never upgraded their manual transmission and clutches to handle more horse power and ft lbs of torture.

Nothing wrong with hydraulic lifters.

Delete it an tune it I bet you could get 500-600hp and 1500+ torque.

This engine is used in 55ton rated semi trucks in the 3rd world 😂 . Hp is lower than the one here. It's about 250hp.

Them trucks are not big enough I pulled a gooseneck with 850 case bulldozer and would run hot it's like driving a freight train with no brakes you can bend the frame really easy I know I did they are not heavy duty you really need a 2 or 3 ton truck or a 18-wheeler I never did feel comfortable with a heavy load

So get the high output n a programmer

Didn't 2nd or 1st gen trucks offer a High Output Cummins? To be honest I fill its just a marketing tool, No reason they cant put the H.O Cummins in a 2500. But your already spending close to 100k Whats a little more🤦🤦

I'm going to need you to put your hand in your pocket...

Ever heard of Scotty Kilmer?

This is too confusing....I can't follow your info anymore.... how about use some graphic organizers to organize your thoughts.... I can't follow....

DUDE, ENOUGH WITH THE HAND THING. MY GOSH

the older style rams look way better

Great video, but your constant insertion of your hands in the video is annoying. It’s like watching a hyper kid.

Ram Cummins junk ,mine a 2019 has failed with only 50000 miles and dealership refuses to repair.Still under warranty with the recall on the engine.I will never buy anything from ram again

Ford and Chevy has more HP

THIS TRUCK IS POWERFUL BUT IT DRINKS DIESEL LIKE A PIG ON STEROIDS 😂. CITY DRIVING 9 ON HWY NOT TOWING 12 MPG TOWING 20,000 LBS IT GETS 6 MPG . IF YOU CAN AFFORD A $110,000 PLUS PU THAN SPENDING $230 TO FILL IT IS PEANUTS. 😂
