The 2019-2021 Ram Cummins 6.7 Full Delete Bundle: What It Fits, What Is In It, and What It Costs

Three model years decide this whole job. The Ram Cummins 6.7 Full Delete Bundle covers 2019, 2020 and 2021. Get that part right and the rest gets a lot easier.

The badge on the tailgate will not settle it for you. You want the door jamb sticker and the build sheet, because two Rams can wear the same paint and still take different parts underneath. That is the one check worth doing before anything else.

We get it — this is not a casual afternoon in the driveway. The parts are heavy, and most write-ups skip the steps that actually bite. So this one goes in order.

What Is the Ram Cummins 6.7 Full Delete Bundle?

The Ram Cummins 6.7 Full Delete Bundle is the 2019-2021 kit for the Cummins 6.7L Dodge Ram. "See Dealer" codes, check engine lights, limp mode, and regen cycles all stop the day the tune goes in. Nearly 70% of all Ram 2500 and 3500 Heavy Duty pickup owners choose the Cummins Turbo Diesel as their powertrain of choice.^[1]

What a full delete bundle actually is

A lot of guys assume a delete is one part. It is not. The Ram Cummins 6.7 Full Delete Kit for 2019–2021 Ram 2500 and 3500 uses the Ez Lynk Auto Agent 3.0, preloaded with your custom delete tunes, to permanently remove the DPF (Diesel Particulate Filter), DEF (Diesel Exhaust Fluid) system, EGR (Exhaust Gas Recirculation), and CAT (Catalytic Converter) from your truck's ECM.

Hardware alone will not get you there. Set aside time for both ends of the job. Hardware and software, together — that is the whole idea.

The four systems the tune addresses

Doing one and skipping another is like replacing three of the four tires. It rolls, and it is still wrong. Half a delete is not a delete.

So plan the weekend around all of it rather than one piece of it. Pull the truck up, stage the parts, and work the list in a single pass. Ten minutes on the floor beats an hour on your back.

What changes on the dash the day the tune loads

The dash is the first place you look. That is not vanity — it is how you know the tune took. Everything after that is mechanical.

So what does the truck feel like on the other side of the install? That part is between you and the dyno. What we can settle here is what ships in the box.

Which Ram Trucks Does the 2019-2021 Bundle Fit?

The Ram Cummins 6.7 Full Delete Bundle covers the 2019, 2020 and 2021 Dodge Ram model years. It fits all 2019–2021 Ram 2500 and 3500 pickup trims, cab and box lengths, but not Cab & Chassis. In 2019, Ram 3500, 4500 and 5500 Chassis Cab models equipped with an Aisin automatic saw horsepower and torque increase to 360 hp and 800 lb-ft.^[2]

Reading your model year and trim off the truck

Start at the driver's door. The sticker in the jamb carries the model year and the build codes, and it does not care what the previous owner told you. That one stop can save you a whole afternoon.

Which bracket does your Ram sit in? Work that out before you touch anything else, because every decision after this one leans on it. Here is the short version.

Where the pickup line stops and Cab and Chassis begins

Here's the thing — a Chassis Cab is not a pickup with the bed taken off. The fitment line above is the whole answer, and it is worth reading twice. Better to find that out now than on the Saturday you have the truck up on stands.

Not sure which one you have? The build sheet settles it, and so does the sticker in the door jamb. Neither one takes longer than a coffee.

Why the year range matters more than the badge

Model years are not decoration on a kit like this. Parts get cut for a specific truck, and close enough is not a measurement. That is why the three years at the top of this guide are the first thing to check and the last thing to argue with.

What Engine Is Under the Hood of a 2019-2021 Ram Heavy Duty?

The 2019 model year introduced HD pickup buyers to 1000 lb-ft of torque for the first time ever.^[1] The 6.7-liter Cummins Standard-Output Turbo Diesel produces 370 horsepower and 850 lb-ft of torque in the Ram 2500.^[4] The 6.7-liter Cummins High-Output Turbo Diesel produces 400 horsepower and 1,000 lb-ft of torque in the Ram 3500.^[3]

Standard output versus high output in these years

So which one is sitting in your truck? RAM 2500 and 3500 trucks equipped with a 68RFE Auto are rated at 370 hp and 850 lb-ft.^[5] That is the number to write on the whiteboard before you start planning power.

The high-output side is a different animal. Check the build sheet rather than the badge, the same way you checked the fitment. Same rule, same reason.

What the 68RFE pairing means for your build

The gearbox behind the engine decides how much of that torque ever reaches the ground. Plan the transmission side of the build at the same time as the engine side, not after it. Guys who do it the other way around learn an expensive lesson.

Write the pairing down next to the model year. Those two lines together are your build sheet for everything that follows. Everything else is preference.

How the 6.7L makes its torque

In diesel engines, internal combustion results in expansion of high-temperature, high-pressure gases, which in turn move pistons, transforming chemical energy into mechanical energy.^[6] That is the whole trick, and it has not changed much. Air, fuel, heat, pressure.

Cummins engines have been an option in RAM pickups since 1989.^[7] In 2019, Cummins celebrated a 30-year partnership with RAM truck that started with the Cummins 5.9L Turbo Diesel in model year 1989.^[5] Refining one idea for that long is why these engines are built like tanks.

What Comes in the 2019-2021 Full Delete Bundle?

A Complete EGR Delete Kit is in the Ram Cummins 6.7 Full Delete Bundle, alongside a Delete Tune and the Ez Lynk Auto Agent 3.0 preloaded with delete tunes. A 4" rust resistant DPF & CAT Delete Pipe is included. The kit also includes a bypass cable and a shift-on-the-fly switch, with an optional 5" exhaust and muffler.

Unpacking the box and checking it against the list

Open everything before you touch a wrench. Lay it all out on cardboard and walk the list once, slowly. A slow pass through the box beats a half-finished truck on Sunday night.

Your parts may look slightly different depending on the version you got. That is normal, and it is not a reason to stop. What matters is the count, not the finish.

The hardware versus the electronics

Split the box into two piles. One pile bolts to the truck and the other talks to it, and keeping them apart on the bench saves you hunting for a cable with greasy hands.

The heavy end is exhaust and EGR work, and it wants a jack, stands and time. The light end fits in one hand. Different tools, different half of the afternoon.

What is optional and what is standard

Not every line on the list is a must-have. Decide the optional pieces up front, because adding them later means a second afternoon under the truck. The good news? It is a short list of decisions.

Write your choices down before you configure anything. A note now is worth more than a scramble later. That is where most of the wasted money in this hobby goes.

What Does the Tune Change on Your ECM?

The Ez Lynk Auto Agent 3.0 connects to your OBDII port and installs the custom tune directly to your ECM, no laptop required. The tune runs five power levels you switch on the fly: Stock […] and +160HP for performance with additional modifications recommended. Transmission tuning is included for the 68RFE, adjusting shift points and line pressure for the added torque.

Loading the tune through the OBDII port

Sit in the driver's seat for this one and give yourself room to not rush. Do not start a tune load on a truck that has been cranking all morning. Batteries and patience run out at about the same rate.

Get the cab tidy first. You want a seat you can sit in, a door you can close, and nothing rolling around by your feet. Small thing, big difference.

Switching power levels on the fly

Levels are a build tool, not a bragging right. Start at the bottom, watch your gauges, and work up as the rest of the truck catches up with you. Nobody ever regretted taking the slow way.

Think of the switch the way you think of gears. You do not launch in top just because it is there. The range is there so the truck can grow into it.

What the transmission side of the tune handles

Most write-ups stop at horsepower. The gearbox is the half that quietly decides whether the build survives its first hard season, and it is the half that gets skipped in almost every video you will watch. Give it the same attention you gave the pipe.

That is real bang for your buck, and it costs you nothing extra. It is already handled. You just have to know it is there.

What the tune is actually talking to

Variable Geometry Turbochargers (VGT) work by varying the exhaust passage area before the exhaust gas entry into the turbine wheel.^[8] VGTs offer versatile optimization across engine speeds and loads, aiding engine braking, exhaust gas recirculation and thermal management.^[8] That is the hardware your tune negotiates with.

In a common rail setup, diesel fuel is stored in a high-pressure rail that supplies fuel to each injector independently.^[9] Fuel and air, timed to the degree. Everything else is detail.

Where Does the Delete Pipe Sit in Your Factory Exhaust?

The delete pipe comes in the Ram Cummins 6.7 Full Delete Bundle. The front end of the delete pipe connects to your down-pipe and the tail end of the delete pipe connects to the tail pipe, just before the bend over the rear axle. The delete pipe is the same diameter of your factory exhaust system, so it will be a perfect fit.

Locating the section of exhaust the pipe replaces

Get the truck up and look for the two joints, not the whole system. The process is identical, and the only difference is the diameter of the exhaust. Once you can see both ends, the job stops looking like a project and starts looking like an afternoon.

Slide under with a light before you buy a single tool. Trace the system with your hand from the turbo back, and stop where the shape changes. That is the piece you are replacing, and seeing it once beats reading about it all week.

Mating the delete pipe to the down-pipe and tail pipe

Work front to back. Hang the pipe loose at both ends before you tighten anything, because a clamp torqued early is a clamp you will be undoing later. Snug, align, then tighten.

Take the weight off the joint while you line it up. A second set of hands helps here more than any tool does. So does a ratchet strap and a bit of patience.

Choosing where the muffler goes

There are two suggested locations to place the muffler. Pick the one your hangers actually reach, and dry-fit it before you commit to anything. Holding it up first beats a second trip under the truck.

There is no wrong answer here, only an awkward one. Look at where your hangers sit, where the spare lives, and where you would rather not be lying down next time something needs a wrench. Then pick one and move on.

What Should You Expect During Installation?

The delete pipe and EGR kit are fully bolt-on with no welding. The first thing you should do is verify you have all the parts. Depending on your truck bed, you may need to cut your pipe to modify your pipe length for fitment. Maintenance intervals for fuel filter replacement remains at 15,000 miles (24,000 km).^[2]

The order to work in

Work cold. Let the truck sit overnight if you can, because hot exhaust and bare knuckles have never gotten along. Then go front to back and resist the urge to skip ahead.

Set your tools out before you go under. Sockets, extensions, penetrating oil, a wire brush. Fasteners that have lived under a truck for years do not come out on charm alone.

Tools you actually need

Nothing exotic. A good jack and stands, a socket set with deep sockets, a breaker bar, penetrating oil, a wire brush and a cutting tool you trust. Add a second pair of hands if you can talk somebody into it.

The one everybody forgets is light. A trouble light or a headlamp turns a long fight into a clean afternoon, because you can actually see the fastener you are cursing at. Sort the light out before you buy anything clever.

Common pitfalls that cost people money

The expensive mistakes on this job are never the hard steps. They are the fast ones — a clamp left loose, a hanger skipped, a mark made in a hurry. Every one of them is cheap to avoid and genuinely annoying to fix.

Rushing the last stretch is the classic. You are tired, the truck is nearly together, and you decide the last joint is close enough. Close enough leaks, and you will hear about it every time you start the truck.

Checking the kit against the parts list

Do the count on the bench, in good light, with the list in your hand. A missing clamp found in the morning is an inconvenience. Found at the end of the day, it is a truck on stands until parts arrive.

Photograph the layout once everything is out of the box. It takes seconds, and it settles any question later about what actually showed up. It also gives you something to point at if you need a hand.

Measuring before you cut

Please make sure to measure twice before cutting. That is the one step in this whole job you cannot walk back. Tape, marker, second look, then the saw.

Mark your cut with the pipe hung in place rather than on the bench. Gravity moves things in ways you did not plan for. Better to find that out with a marker than with a saw.

What the maintenance schedule still asks for

The truck still wants its scheduled service afterwards. Put the next one on the calendar the same day you finish the install, while the job is fresh and you still care about it.

Filters are cheap and injectors are not. That is the whole argument, and it has not changed. A little love goes a long way on a workhorse like this.

What Does the Bundle Cost, and Who Should Buy It?

The Ram Cummins 6.7 Full Delete Bundle is listed from $2,494.00 to $3,109.00. Ez Lynk is built to order and non-refundable; pipes are final sale; the EGR kit is returnable unused within 30 days with a $30 restocking fee. The 2021 Ram Heavy Duty offers a towing capacity of 35,100 pounds and a payload capacity of 7,680 pounds.^[3]

What the price range covers

The spread is the options, not a moving target. A base build and a fully optioned one sit at opposite ends of it, and everything in between is a choice you make when you configure the kit. Decide those choices before you get to the cart.

Think about what you want out of the truck before you look at the number. A build that stays close to standard and a build that goes the whole way are not the same purchase, and the range is just that difference written down. Pick the truck you want first, then read the price.

Ram Cummins 6.7 Full Delete Bundle | 2019-2021

Return terms worth reading before you order

Read the terms before you click, not after. The window on the returnable piece is short, so unpack and check the day it lands rather than the weekend you plan to start. That is the cheapest insurance in this entire job.

Built-to-order electronics and cut pipe are a different category from a shelf part. Treat them that way and there is nothing here to be surprised by. Know it going in and it is a non-issue.

Who this bundle is built for

If your truck is a 2019, 2020 or 2021 Ram 2500 or 3500 pickup, the Ram Cummins 6.7 Full Delete Bundle is the one to buy. Cab & Chassis owners are looking at a different machine with a different parts list. That is not a hedge — it is the fitment line doing its job.

You are buying one decision instead of a stack of them, and that is most of the value. The parts match, the tune matches, and the year range is not a guess. For a truck you plan to keep, that is the version of this job worth doing.
