6.4 Hemi 2500
 
Who's got a '14+ Dodge with the 6.4L? Thinking of selling my 04.5 Cummins and going to a new gasser. I don't pull heavy enough, often enough to justify the $9k buy in on the Cummins and honestly all the new emissions shit scares me on them with some stories I have read. Anyone gone from a 325/610 Cummins to a newer big block Hemi and regretted it? Towing duty would be my bumper pull toy hauler that weighs around 11k fully loaded once a month or so.

We have a bunch of them at work. They seem adequate, but it's a gov't fleet that never leaves a 50 mile circle of flat land. A buddy of mine had a new one last year and got rid of it due to oil consumption. It would smoke on start-up after sitting for an hour or so after driving. It used too much oil between changes for his comfort. A couple of our work trucks will blow a blue cloud on start-up like his did, though I don't know how much oil they're actually using. I don't think this is anything new with vehicles that have MDS though, my brother says his Honda uses oil too. None of our 5.7s do this, and my wifes manual trans Challenger 5.7 uses zero oil between changes. I don't like the idea of new vehicles using oil in this day and age, seems like BS to me. The 6.4s do haul ass empty though.

How many empty miles do you plan on putting on it? It seems that's where the fuel expense favors a diesel truck.
If I were shopping new, or almost new, I'd be looking at had trucks myself. Ford 6.2s seem to have the edge tho

Elwenil 02-09-2018 10:48 AM

A friend of mine had a Cummins Megacab but got rid of it since the wife didn't like the 6 speed and he went to a Power Wagon with the 6.4L to tow his camper. I towed the camper with that truck once for him to take it to get some work done to the camper and while it had plenty of power, it kind of grated on my nerves pulling hills with the V8 screaming the whole time. Recently my friend went back to a Cummins with the automatic and seems to be happy with that.

That is one of the most annoying things about towing with a gasser. My 3V V10 is loud at 4000 rpm.

Most miles will be either empty or pulling my 12' trailer with the RZR on it. I only tow the camper every couple of months. For the $9k less for the gas motor over the Cummins I can buy a lot of gas. Plus gas is $.50-.60 a gallon cheaper than diesel where I live and almost always is so the improved mileage from the diesel is probably negligible when you factor in the increased cost of #2 over gas.

ramv 02-09-2018 02:00 PM

I like mine. 14 -15 mpg empty, no oil consumption. (My Chevy got about 12 and burned a quart of oil every 3k miles.)

Good power empty, tows my 2nd gen on the heavy trailer good enough (12klb or better) and tows my 5klb camper easily.

4.10s and 35"s.

If I was towing a big fifth wheel or two place car hauler all the time, I would go diesel, but for normal use it's cool.

fearfact 02-09-2018 10:53 PM

I have a 16 3500 Ccsb 4x4 with almost 60k. I am extremely happy with it. I do haul equipment often-around 14k load-here in NH so hills,highways and backroads often. Only bitches I have are I hate the mirrors and the only reason my next truck will be a diesel is for the engine brake.

rusty 4x4 02-10-2018 05:09 AM

I've been pretty happy with mine. I average 13-14 mpg with about 28000 miles on it. Towing it is generally in the 7-10 mpg range. It definitely doesn't have the low end power that my diesel did though. The only problem I've had with it is the transmission shift solenoids going out and putting it into limp mode. Ram has since came out with new solenoids and I haven't had any problems out of them.

wades_76_cj7 02-10-2018 09:13 AM

Talked to a buddy yesterday that has a '15 CCSB Cummins with 6 speed auto that is wanting to upgrade to a new truck. Gonna buy his for trade in value. :grinpimp:

I have driven it before and it's a nice truck. With only 40k on the clock it should last me another 12+ years like my 04 has.

Sounds like a win. Aisen, 68RFE or G56?

They are really nice/solid trucks. I think you will be very pleased. 50k miles on mine.

he wasn't sure but from my research the 2500 Cummins in '15 was only offered in the G56 and 68RFE?:confused: I thought the Aisin was offered too but maybe that was only in the 3500?

ramv 02-10-2018 11:23 AM

Yes sir. I believe the Aisen was only an option in 3500s. You will be happy with the 68. They work well.

landscraper 02-13-2018 11:56 AM

I bought a '16 with ~17,000 on it on Halloween. I've put about 5k on it since then. Averages 12 mpg, mostly around town. It'll do 15-16 mpg on a 55 mph highway. It will haul ass empty, and doesn't slow down much with 5k behind it. Can't say on heavier loads because they go behind a bigger truck.

My only real complaint is the variable displacement. It comes in and out at inopportune times and makes the truck feel like it shifts too much. Also, at certain load/RPM combos it's pretty loud in the cab.

I went with the Laramie with leather, and it's very comfortable and nice to drive. But as of now, my plan is to pay it off in 2 years and go back to diesel. Find one just out of warranty and delete it.

ramv 02-13-2018 07:03 PM

You can turn off the MDS. Simply select "6" with the +/- shifters. This also shows the gear you are in. I always drive like this as the MDS was annoying. It doesn't hurt/impact anything else except the variable displacement from engaging...

Just watch the GVW on the Power Wagon. It's only about 8500lbs where a normal 2500 is 10k lbs. Quite a loss of payload with the Power Wagon package.

I was looking at the Power Wagons thinking 3/4 ton Rubicon til I saw the reduced load capacity. There are several on Autotrader in my area with pretty low miles too. Does the mileage suck that bad that people buy them, don't drive them much, then trade them in? :confused:

Saluki ATO 02-14-2018 01:05 PM

I dunno. I love mine.

12-14 mpg on 37s with stock suspension
Lead trail runs a plenty and have trailered home rigs that broke following me
IMO, handles a single rig on a open trailer great

ramv 02-14-2018 07:26 PM

Love my Power Wagon... GVWR Nazis won't buy thm, but I can tell you, everything is the same as a regular 2500 except tires, wheels, and rear springs.... Wheels are stout (Alcoa designed) tires are 17" 3195 lb load rating. Springs are a bit softer/taller than 2500s.

Stock, mine handled the 1500 lb TW of my trailer no issue. I have added airbags/daystars as I plan to run some additional weight (after first checking there are no bus loads of nuns on the road.)

Was the G56 available behind the 6.4 in 15? For some reason I thought they quit with the manual behind the gassers?

They did quit the gasser manuals, I think it was when the current body style started. It sucks, I think a 6.4 or even 5.7 backed by a G56 would be pretty sweet.

I had Timbrens and 5100s on the Avalanche. I would say the stock PW (4600s) handles loads about the same as the Avalanche with TImbrens. THE GVWR is as actually about the same between both (~8600 lb) but the PW definitely handles load more like a truck.

Aggie06 07-13-2018 01:22 PM

Bumping this thread. In search of my next truck and considering a 2500 with the 6.4. Any problems anyone has run into with them? Anyone have a mega cab with the 6.4? If so, do you regret not getting the diesel?

Buddy has a 2014 3500 6.4 hemi for his work truck.he has towed tons with it including backhoes. His biggest complaint is not low enough 1st gear to get going. It has 220,000 miles on it now and recently lost a water pump towing his camper up the mountain so swapped trucks with a 2015 Chevy 6.0 truck and he felt it pulled better, mostly because of lower 1st gear gearing. We looked it up and if I remember right the dodge was like 3:1 first whereas the theft is about 4:1. Overall though I think he really likes the truck otherwise and has been well tested.

fearfact 07-14-2018 07:14 AM

Only problems Iíve had so far with my 2016 srw ccsb 3500 is the transmission valve body shat itself at 67k, warranty repair and back in the road. I tow about 13k often and right n the truck all over hell for our construction co. Overall very happy with it but my next one will be an oil burner primarily for the braking and plan for a heavy gooseneck setup

KungFooMASTA 07-17-2018 11:30 AM

Is the 6.4 Hemi actually a big block? Or do you just call it that because its bigger than the 5.7? If it is a big block that is a pretty small one.

BroncoAZ 08-03-2018 08:39 AM

Iím debating going from a 2006 5.9 diesel to a 2500 or 1500 gasser. Iím not driving or towing enough miles to warrant keeping the diesel. I want to make the truck my wifeís daily driver, she put 8K on her Lesbaru last year. I tow my Bronco (8700# with trailer) once or twice per year no farther than 400 miles.

Iíd rather have a 1/2 ton truck for her to drive and for fuel economy when we do go on trips (unloaded), but regardless of claimed ratings Iíd be displeased towing 9K with it after owning a 3/4 ton for the past 10 years.

As for which gasser, Iíd want to try them all and see what drove the best. The Ford 6.2L had the best MPG in a review video I watched recently and is available in a super cab vs a crew cab. My garage minus door is about 19í 9Ē, my current regular cab long bed truck fits with a few inches to spare. The Dodge 2500 crew cab is 19.78í long whereas I can get a Ford or GMC a little shorter.

lunacy 08-03-2018 02:19 PM

I just picked up a 2017 RAM 1500 Quad cab, short bed hemi with 22k miles for $23,000. Getting ~16mpg it replaced my 08 1500 Hemi, getting 13mpg.

I was looking for a similar 2500 6.4L, but just couldn't get to my price point, they were $10k+ higher.

Like you it's an unloaded daily driver most of the time, I might tow 9000 lbs twice a year and 5000 lbs 10 times a year. I did it with my 08, so I'm figuring the 17 should do it too. 9 years in truck technology is nice, this thing rides a lot better, seat is more comfortable, accelerates faster, bluetooth phone/radio and back up camera kick ass...just hoping it holds up as long.

Saluki ATO 08-03-2018 03:01 PM

2.5 years and 50k miles on my '16 Power Wagon.

Was getting antsy, so I was thinking about a diesel. Test drove a 17 and an 06. 06 felt stronger than the 17 (unknown mods on each). But neither was good enough empty to make me really motivated to change.

Still daily driving the 6.4 12-13 MPGs on 37s with stock 4.10s and lots of city streets. Towing 7-9k every 1-2 months. Sure it sucks the fuel when towing fast, but it's not frequent or heavy enough to make a change anytime soon.

8 speed or 10 speed in the 2017s?

What gears?

lunacy 08-03-2018 04:03 PM

it's the 8 speed. 3.21 rear gear. The 8 speed has a 4.71 first gear, so even with the 3.21 rear end it still has a lower first gear final drive than my 08 with 3.0 first gear and a 3.92 rear end, and about equal for second gear. It takes off pretty quick.

I cruise 80mph at ~1700rpm, in my old truck it was ~2100 rpm.

Chevy puts the 6.2L in their half tons, as an option

You can get the 6.2L in some select F-150s

Does Dodge have any options for a larger motor in their 1500s, other than the 5.7L?

I dont think they do but haven't looked lately.

My 16 ram 1500 pulls my jeep just fine. Trailer and jeep is right at 7klbs. Loaded it get 10-12mpg depending on if doing 80 or not. Unloaded I am getting in the 20ish mpg.

This truck has the 3.21 gear in it and it pulls as well as the 10 ram I had with the 3.92 gears.

lunacy 08-06-2018 09:33 AM

5.7 is the only v8 available in the Ram 1500. I hear they are going to put the 6.4 in it, but that's rumors been going around for a few years.

I wish I got 20mpg out of mine, but I think my right foot is a little too heavy. My dash says it's getting 17.4, but my fuelly app hasn't calculated above 16.5 at any fill up. Maybe once the temperature gets under 100 it'll get a little better.

Itll never happen. FCA is the queen of faggotry, still waiting on the EPA to approve the 48v generator hybrid system. The only engine available in a 2019 is the standard 5.7L.

lunacy 08-09-2018 01:38 PM

Too bad the golf cart starter/generators on the 2019s aren't getting through EPA yet, its an interesting concept. They still have some 2017 Ecodiesels new on lots too because those got put on hold. Damn European junk, sad that Chrysler can't get back to being an American company.

I have a 07 2500 4x4 with the hemi and g56, not as exciting as you would hope. The G56 is a lot lighter in the clutch department only sporting 11" instead of the cummin's 13" but it at least has a solid flywheel rather than the dual mass. Input shaft is also substantially smaller than the cummins equivalent.

Power doesn't feel any different than the autos but more useable. Mileage is about the same as an auto, best I've seen is 17.5 completely empty and driving like a puss. Haven't had it hooked up to any substantial load yet.

I need to buy a truck very soon to replace my 1999 454 burb. There are a lot of nice 1500 5.7l trucks out there for sale. I have been looking at the following 2012 - 2017's:

6.2l ford
6.4l hemi
5.7l hemi

My rig will mostly be a daily and tow 7k once a month. There will be some planned multi-state trips this year.

dickwart 02-22-2019 02:58 PM

I'm in there with a 15' Ram 1500 on 35" Toyo AT2's. Towing probably 6-7K and it hauls ass. Not passing a gas station but it does have a smaller gas tank, less than 30gals I believe. Not sure of actual MPG, never recalibrated the speedo but I'd guess mid teens. I don't tow at 55 :). Added bags just because the rear coils were a little soft for my liking. Make a dozen local trips and half dozen 300+ miles one way out of town trips every year for last 3 years and seems to be doing fine. I pass all my diesel buddies, except for the refueling part...

Aggie06 02-22-2019 03:20 PM

Have had my 18 2500 Mega Cab with the 6.4 for a little over 11K Miles now. Overall average is around 13.5. Thatís with stock tires and mixed city/highway driving. Had no issue pulling a 29í Jayco travel trailer around CO when we went elk hunting this past fall. It wonít win a race pulling the trailer over passes, but it does everything I need it to.

You driving one of those now huh? Looking at all of the half ton's out there...I don't think I can really go wrong anyway. My burb only had 290hp new but 410ft/lbs of torque. All of these new motors seem to be at 383hp or more and 400ft/lbs.

Same if not more wheelbase and more gears in the tranny means it should be a smoother pull as well.

Lastly...with the 454 I get 7.5mpg towing and 9mpg around town...:mr-t:

My wife has a 15 ram 5,7, speed, 3.21's . The max tow rating is 7k with 3.21's, 10k with 3.73's. My wife's truck gets good mpg (16/21), but not sure I would want to tow 7k with it. It rides great and is pretty quick. I had a 3500 with 5.7 and 4.10's, with 9k-10k toy hauler it was a 6mpg dog. 7k on flat's it would have been ok but not in the rockies. If you get he 1500 ram, I would get the 3.73's and plan on sway bars for a 7k trailer. The hemi likes to pull hills at 4k-5k rpm, takes a bit to get used to.

I just picked up a 18 ram 2500 diesel, winter driving with studs and in 4x4 50% I'm getting 14-15. Hoping for 12mpg with the trailer when the snow melts. But I'm mostly towing around NW MT.

I need to buy a truck very soon to replace my 1999 454 burb. There are a lot of nice 1500 5.7l trucks out there for sale. I have been looking at the following 2012 - 2017's:

6.2l ford
6.4l hemi
5.7l hemi

My rig will mostly be a daily and tow 7k once a month. There will be some planned multi-state trips this year.

I should be but I dont use the trailer brakes with this set up and it did just fine. I have had a few dodges and like them the best.

I have had an f150 work truck and I absolutely hated it.

Yup 5.7. Been up over Snoqualmie over to Crashes to run Reiter and back over Stevens, and been down central OR with it a bunch so up out of Biggs and couple other nasty steep hills coming back...

What trans is bolted up to these 6.4L trucks?

6.4L is only a power wagon and a 2500/3500 motor right?

You sure about this? Tried to tell my buddy about this and he said it did not work

He is averaging 7.8-8.5 in his 6.4L PW , unloaded

Stock, or larger tires? That seems pretty bad. Hell, thatís Chevy 6.0 range.

I will have to try turning off the MDS on my truck. Havenít ever messed with it.

Works on my '16 PW. I'm running 37's and am getting like 10/14 unloaded indicated on the computer. Computer lines up with hand calculated =/- 0.5mpg. That's with a speedo that is uncorrected for tire size, so it's probably actually a little better. I don't drive it very hard.

My understanding is that there is no way to untraceably turn the MDS off permanently. So if you have a warranty, you are going to have to buy a second ECM to swap in when you take it in for anything. It's not like a GM MDS system where you can just get an OBD dongle to turn off the MDS, then remove the dongle to set everything back exactly how it was.

I think you get the 68RFE. 6 speed auto that seems pretty good in the short time I've had it. I don't know if you can get an Aisin in a 3500/6.4 combo.

16 PW on Toyo RTs 37x12.5 and corrected with AEV ProCal here. 11-12 unloaded here. Mostly city or going above southwest interstate speeds. 8-9 with either a single rig or small camper so far. Regearing to 5.13s in the near future now that I've got a little DD.

66RFE which is some combo of 65 and 68 architecture from other reading.

How do you like the AEV ProCal? It looks like I need one of those for my re-cal and a Range Technology disablement tool when (if) they come out.

It does what it's advertised to do. I tweaked the speedo a few times the first day and haven't touched it since. It's too bad the TPMS requires a dealer visit (or full scan tool) BCM reset.

I'm hearing that AlfaOBD is the way to go now though. More functionality than the ProCal which is just dipswitch uploads.

pcorssmit 03-05-2019 01:02 PM

I actually just reset my TMPS threshold on my 2015 a week or so ago with AlfaOBD. No more orange light on constantly, plus the EVIC display stays on wherever I left it now instead of going back to the tire pressure screen every time I start it. I haven't messed with the speedo yet, but it sounds pretty easy to do.

Android only is a bit of a drag. Search led me to RamForum. There's actually some decent tech there and a good bit of traffic.

pcorssmit 03-07-2019 12:47 PM

I first looked at getting the windows version (since we didn't have any Android devices), but ended up getting a $50 Fire 7 tablet to run it. I haven't used it a lot, but so far so good. As a bonus, I can use it to stream music in the garage instead of having to use my phone.

looking into that, the tire warning bullshit is annoying. I run my winter studs at 45psi unless I'm hauling.

Apparently theyíve made it harder for 2018+ models. Iím sure someone will come up with a solution eventually. Going to keep watching it as I like running mine around 65 if not towing.

You can still do it with alfaobd, you just need a bypass harness due to the security. Look at the thread on ram forum or Cummins forum, it's all there.

You can get a 6.2L V8 in some F150 trucks and GMC/Chevy offers their 6.2L V8 in the Silverado/Sierra 1500s........but only one V8 is available in the Ram 1500?!

What's the power specs of the current 5.7L Hemi?

Pulled the trigger last weekend on a 2015 F150 3.5L EB with 56K miles. So far the truck is a dream.

I really like the layout of the F150 over the Hemi.

Anything change with the 6.4s over the years?

For 2014-18:

Front AAM 9.25Ē
Rear AAM 11.5Ē

Those may have changed in 2019, but Iím not sure.

Not sure if anything has changed on the 6.4 over the years. Seems like some people have issues with the mds system. You can go with the hellcat delete, and it addresses the issue.

What years are the radius arms vs the 5 link?

19 gets the HD8speed auto. I haven't driven one but have read reviews. All of them were extremely positive.

D45 03-29-2019 10:22 AM

All the previous year trucks use the 6 speed auto......Dodge, Ford, GM

Ram 6.4L
410 HP @ 5600
429 TQ @ 4000

Ford 6.2L
385 HP @ 5750
430 TQ @ 3800

GM 6.0L
360 HP @ 5400
380 TQ @ 4200

GM 6.2L
420 HP @ 5600
460 TQ @ 4100

Does the GM 6.2L require premium fuel?

gunracer1 03-29-2019 10:32 AM

i have never put premium in mine.

IIRC you need premium to see the 420/460 numbers but is still just fine on 87.

I have my eye on a 2015 2500 with the 6.4L

Not a fan of the rear coil setup.......rides great for a 2500, but I have heard that it sags fast under load

Any issues with the 2015 model year?

Donít know of any issues specifically.

I would suggest finding a truck with 4.10s if possible if you plan to tow a lot.

The springs are only part of the problem, the rear track bar is the other issue. The problem seems to be when the truck starts cycling a lot, the rear track bar causes a decent side to side motion. When towing this can cause some instability. The stock springs are progressive, the initial is fairly light, and then a much heavier 500ish lb/in rate. You basically want a decent amount of tongue weight to get the rear well into the secondary spring rate and keep it planted.

I swapped in some 1" taller lower rate soft ride coils in the back to get rid of some of the harshness. I then found it had too much "but wiggle" when hitting large bumps and dips at highway speeds. Towing was fine however as the suspension sagged a bit. I threw a 3" rear track bar raise on it and that fixed that issue when empty. Its solid and drives great now. I do wonder if a track bar raise would benefit a stock height truck also.

These are the only problems I've seen so far. I do wonder if the rear link design being so high and leveraged on the rear axle will cause premature bushing wear? The rear bushings are larger than any I've ever seen on a 3/4 or 1ton truck however.

Not sure if it's the same engine but my tuner buddy was saying that the pistons in the 6.4 are weak if you want to do power adders of some sort. They did that in the challengers so you could buy the 6.4 and throw a blower on it and have a hellcat for less.

Yes, 2014+ will have the coil sprung rear. It will also have 4.10 gears instead of the 4.56 in the 2013 and older PW.
