This is the best truck i’ve ever seen in my life...Great work

[@bigal1568]

This is about the best build I have ever seen

[@rsmillican3299]

I have a 2000 K 2500 crew cab . We completed the swap and I have had the truck on the road since January of this year. I am enjoying it very much. Joel I have watched this video and your others ,I don't know how many times . Joel you have been a great encouragement during my process. I will continue to watch because it helps me to think through some of my processes. Thank so much !

[@justadon2832]

About how much would you say one of these swaps would cost,im interested in swapping my 98 k3500 daully 454 powered

[@jcallum8408]

Love it! Spare no expense. I love the GMT400 platform. I'm getting ready to do this to a sano, one owner, 94 K2500. The 6.5 shit the bed and I already acquired a 96 donor for the Cummins. Your video is an awesome resource. Thanks!

[@matt.s4440]

did you ever finnish it? Im getting ready to put one in my 96 k2500

[@salvaje9382]

Finally a straight up video. Thanks bro!

[@markmiller6642]

Alls I want to say is you stand alone in your skill level and attention to detail sir ! I have seen many mechanics that wouldn't make a flea bite on your skills

[@jimkillen1065]

Nice build , one thing I wondered is the convertor and if it was for a diesel or the stall speed . The lock up function and shift strategy . Thanks attention to detail really shows

[@joshsosbee8820]

Im telling you, if I didn't love my F350 CCAB, I would totally build this! Id love to see a Square Body Suburban get this same treatment! Very nicely done!

Very Nice! I just bought a clean 99 with a blown up 7.4 and my first thought was cummins swap.

[@Jonesys]

Great first thought!

[@kevinscheimreif7866]

Great job, I wish I had kept my square body and swapped out the 6.5 for a cummins

[@enriquecastellon6524]

Really nice. I like it. I could live with that For the next 20 years+. Travel would be really nice with decent fuel mileage to go with it.

I’d love to swap a 12V 5.9 Cummins married to an Allison into a 1991 Suburban 2500.

[@Scholioso]

Hey JonesysAutoClub. I have some follow up questions. I will be doing the same conversion soon. Some questions I have are how has the 4l80e held up? More specifically, what stall did you end up using? Hows the US Shift controller working? Anything you would change if you could do it again? Thanks! I'm sure I'll have more questions but thank you for your time! Good lookin rig!

[@markwilson9760]

Beautiful clean truck. Nice job

[@BolteBuilt]

[@JohnSmith-qj4cf]

Beautiful conversion !what tquke converter did you use thks

[@kamsden13]

Awesome build.

[@Edhooey]

Awesome! Between the larger tires and the increased weight from the Cummins, did you do anything to help the front diff cope? I have a '97 K2500 that I love, but I'm definitely aware that those front diffs are a weak point. SAS is one solution, but that IFS ride is so nice...just curious if you found a satisfactory compromise?

[@KhalidAlmuneef]

Hi, This is amazing work 👍👍. I have 1996 gmc serria 12Vcummins swaped and its working good . I have qustion if you can help me on it . How can i used the orignal dashboard RPM with cummins? i tray many ways but i get nothing. Thanks.

[@timkebienda1809]

Can you install a dry sump to an 4bt or 6bt engine to help with clearance ?

[@wildincanada]

Hi I was wondering what driveshaft modifications did u have to make u said u have too move the trans back 3 inches so did you have to shorten the rear driveshaft and lengthen the front ?

Sweet but the new engine you dont have to use any motor mount like muve them and weld new mounts , i have a dodge 1951. Dually flatbed and the donor truck was just like yours dually dodge cummins 1996 you think is easier SWAP the cabin' or SWAP the engine , transmission and dif'????

[@corndogg_4209]

So does it have to be a 4x4 or can it also be done in a 2wd 99 3500

Do you make the swap parts in this build available for purchase?

Enjoy you videos are you in Canada? If so what area ? Cheers.

[@bradleynaffziger3200]

Are the swap requirements the same for a 99 Chevy k2500

[@montycrain5783]

I Like It. You should try a Turbo 400 transmission and a Gear Vendors GearSplitter/Overdrive. A Non electronic transmission to match the Mechanical 12 valve And the GearVendors unit to split the gears making it a 6 speed Overdrive.Although it is electronically operated, when turned off the transmission operates normally.

[@Jonesys]

4L80E with the programable controller works great.

[@rsmillican3299]

@@Jonesys I have the same transmission and same programmer on my 2000 k2500 with a 98 5.9 12 valve , I have had it on the road since January of this year. I t works very nice.

[@tangerine5781]

Do you need the torsion bar drop if your planning to just run rwd and not 4x4? And modifications done to the firewall? Notch the subframe for the oil sump? Any notching of the frame to clear the engine?

[@Jonesys]

Nope the engine fits perfectly. You need to bend a pinch weld seam a little in the transmission tunnel and the suspension lift helps but is not required.

[@kevinmoak429]

Could you put a 6bt in my 94 Chevy 3500

Hey thanks!

[@kolourblind3124]

Think I would have done a straight axel swap...did you consider that when doing this build? Thanks for the video!

[@stevenhorsefield2909]

That's what I did on my conversion build dana 60

[@jasoncarpp7742]

What was the engine size of the original engine before the Cummins swap? If I remember correctly, the Chevy/GMC Suburban was available with everything from a 5.7 litre V8 engine to a 7.4 litre V8. By the time this Suburban was offered, you could also order it with a 6.5 litre Detroit Diesel Turbo if one wanted.

[@Jonesys]

7.4L V-8 Gas

[@jasoncarpp7742]

Ahhh! Okay. So a 5.9 litre Cummins Diesel would've fit comfortably inside the engine bay.

[@amosfoley585]

I’ve got a 1998 gmc suburban that I’m very heavily considering this swap and I’m just curious how you did the 4wd? Any tips to make it easier would be great thanks!!!

[@Jonesys]

It came stock with 4wd. The engine swap did not affect the IFS or the 4WD as the stock transmission and tranfercase were retained.

[@keeganspeed]

You siad in the video that you had people asking if you would do such cummins swaps for people. If that is true im very interested in having you do something very close to this in a 98 k2500 chevy.

[@Jonesys]

Yes send an email outlining the scope of work to [e-mail].

[@jshpalma]

Around how much was this build cost around

[@graysonsgarage5157]

How can this vehicle retain the 4x4 and the IFS without needing a body lift? Also I'm concerned about the 4L80e not being able to support the beating that the Cummins can throw at it. It the tranny built or does the modified shift timings from the trans controller make up for that? But overall, that's an awesome build, I dream of one day doing a 12v swap into a K3500.

[@Jonesys]

Neither a suspension lift, or body lift is required but they do make the install easier. The transmission has been fully rebuilt with HD clutches, convertor as well as valve body upgrades. The stand alone controller from US shift makes programming easy. The 4L80E is a great very heavy duty transmission and since this vehicle will not see much towing it is a great choice. Thanks for the comments.

[@joeyscleaninglady2877]

who did the transmission upgrades and rebuild? Are you using stock stall speed?

[@Jonesys]

Everything is done in house. Lower than stock HD convertor Alto RED clutches as well as valve body mods and upgrades. This is not Rookie camp.

[@joeyscleaninglady2877]

nice!

[@oafyvonskidmark316]

The 4L80e is based on the Turbo 400 transmission, the 4L80e has a 25% overdrive, the torque converter locks up 1 to 1, it is the heavy duty model there is a 4L60e that is weaker than the 4L80e ,the e stands for electronic. There are modified units available at Jegs and related outfits for high stall torque converters or heavy duty converters, the stock one will be the weak link in my opinion. Turbo 400 tranny's were put in motor homes behind 454 big block chevy motors.

[@neighborhoodcrime148]

I just wanna know how you made the 37s fit on. The 6 inch lift? With no 3in body? What did u cut off The fender?

[@Jonesys]

Just a little trim on the rear flare.

[@theinnovativeassociate4809]

Amazing truck, What did you use for motor mounts? Are they custom made?

there is people that like to knock on Cummins motors but they are very tough pulling beast I should know I have truck with a 12 valve in it and I have done a lot with it too so I know a lot about these engines

[@bonnieclyde100]

not sure if anyone asked this already but does your abs still work without the factory computer being there? I have done this swap on a 97 3500 dually and my abs doesn't work. I have a scan tool that should communicate with abs computer but doesn't . I even bought a used unit and it wont communicate with it either.

[@Jonesys]

Yes, the abs is still hooked up and fully functional.

[@PBMototsports]

Do you guys make or sell a conversion kit to do this? I have my dads 89 k3500 extended cab dually that I am restoring and would like to cummins swap it. It also came factory with a 454.

[@clank0r]

Where does the DSL-1 E get its input signal? What did you use as a reference to calibrate the tach reading?

[@Jonesys]

The tach signal is pulled from the "W" terminal on the alternator and was calibrated to 750 RPM which is where the cummins is at idle.

[@clank0r]

Thanks for the reply. That's a very smart and economical solution to that problem. I saw in another detail that you were using a GM alternator and I figured that's what you must have been up to.

My question is..... How much time. And how much does it take for a set up like this(minus the paint) ... I have a '98 Burban that j would live to convert

[@Jonesys]

Diesel conversions start about $15K for just mechanical and drivetrain. Interior, lift, paint, bumpers, big tires all add to the cost. More videos about that topic will be posted over the next couple months.

[@stevenhorsefield2909]

I had about 12k in mine and it took about a month to do it.

[@joej.9584]

Very very impressive swap, my only two questions is why retain the suburban transmission? and why not instead of doing all this hard conversion shit and just buy a ford 7.3l excursion? They're badass and bulletproof. lol

[@Jonesys]

Ford vs Chevrolet. International vs Cummins. It all boils down to personal preference. My vote obviously goes to the fully mechanical diesel that gets 18MPG and the simple programable transmission controller. Wrap that with the suburban sheet metal and great leather interior and you have a package that beats the overly complicated 7.3L excursion everyday of the week.

[@JosephusHeun]

I just bought a 1999 3/4 ton with the 454 to do this conversion. I have a buyer for the 454 motor. Do I need to keep the ECU or does it get completely bypassed?

[@Jonesys]

You don't need the ECU. You do need a stand alone transmission controller. I recommend the US shift.

[@JosephusHeun]

So how hard is it to get all the gauges to work without the ECU? I have a guy wanting to buy the 454 that's in my Suburban but I'm hesitant to sell him the wiring harness and ECU.

[@Jonesys]

Your gauges do not come from the ECU. They do route through the wire harness so if you are selling the gas harness with the 454 you will have to run the sensor wires separately.

[@jacobschaik828]

Hi, I’m a high schooler looking to buy my first truck. I have my eye on a 1997 dodge Cummins that has about 240k miles on the engine. It’s a two door with a lift kit. I wanted to get your opinion to see if the $9,000 that it’s listed at is worth it?

[@Jonesys]

Things are worth what people are willing to pay so if that is the best truck that you can find for that price then yes it is worth it. Can you find other trucks that will get you back an forth to high school for less $$$? Absolutely...... I started with 1977 4 door 6 cylinder chevrolet nova as my high school car.

[@gstubbz]

Cummins owners are high, I'd rather buy a 96-00 GMT400 with a Vortec 5.7 instead as a first vehicle. Mine never left me stranded and I wasn't nice to it. Trust me I wanted a Cummins when I was 16/17 too but if shit broke it wasn't cheap to replace parts.

[@jackpinnell3973]

Awesome video! You mentioned moving the eng/trans back 3" but you don't mention anything about having to modify the firewall to get everything to clear? Did the firewall get modified in any way to make room for the engine? thanks, really enjoyed this video!!!

[@Jonesys]

The firewall does not need to be modified but there is a pinch weld that needs to be bent back to provide more clearance in the transmission tunnel.

Would you be able to do a swap into a 1/2 suburban?

We will only install a 4BTs in a 1/2 ton Suburbans. A 6BT is too heavy for 1/2 ton suspension and it builds too much torque for the 1/2 ton transmission, transfercase and differentials.

[@joeyscleaninglady2877]

seems like overkill when a 4bt would do.. what airfilter is that?

[@flex93312]

Joeys Cleaning Lady Why put a loud 4bt that sound like a tractor truck & has less power. The 6BT is quieter, a lot faster and has a lot more pulling power.

[@Jonesys]

4BT is not a good choice for a vehicle like this when a 6BT fits perfect makes more power and cost the same if not less to install than a 4BT. Flex93312 is totally correct. FYI the air filter is a WIX 46637.

[@joeyscleaninglady2877]

I have seen many suburbans/tahoes etc with 4bt's they are much more economical and make big power (especially p-pump variant) the 6BT is overkill for this application. I love my 4bt in my CJ works well and more efficient than a 6bt

[@Jonesys]

6bt is overkill in a 3/4 ton truck with 37" tires? OK...........

[@joeyscleaninglady2877]

4bts are used in a lot of power wagons with the same spec.. no issue.. claiming that a 4bt cannot work properly in this application is foolish...

Can you do the setup without the stupid computer?

[@Jonesys]

If you run a manual transmission

[@thumperjoey1]

What about a built Turbo 400 or a 460L?

Yes, you could use a TH00 but then you would not have an overdrive. 700R4 or 4l60 are not a good choice.
