What exactly comes in a Ram 6.7L diesel All-in-One Delete Kit?

Our Cummins All-in-One delete kit include all the hard parts needed to physically remove the restrictive factory emissions equipment. This typically features a high-flow exhaust race pipe (to replace the DPF and SCR/DEF filters), CNC-machined EGR block-off plates, high-temp silicone coolant reroute hoses, and a CCV (Crankcase Ventilation) reroute kit.

Do I have to run a custom tune after installing these delete parts?

Absolutely. Removing the factory emissions components will cause your truck's ECM to throw dozens of Diagnostic Trouble Codes (DTCs) and immediately go into Limp Mode. You must use a capable tuning platform (such as EZ Lynk, MM3, or similar devices) loaded with custom delete tunes to electronically shut off the sensors and stop exhaust regeneration cycles.

Which Ram heavy-duty models are these kits compatible with?

Our Cummins delete kits are designed as direct-fit upgrades for all 2007.5 through 2021 Ram 2500, Ram 3500, and commercial Cab & Chassis trucks equipped with the 6.7L inline-6 diesel engine.

What kind of real-world performance gains can I expect?

By removing the massive exhaust restrictions and applying proper tuning, you can expect dramatic improvements. Typical gains range from +50 HP for safe, heavy towing tunes, up to +150 HP for aggressive street tunes. Additionally, most owners experience a significant drop in Exhaust Gas Temperatures (EGTs), much faster turbo spool-up, and a 2–4 MPG increase in overall fuel economy.

Are these emission delete kits street legal?

No. All SPELAB DPF, DEF, and EGR delete components are strictly sold for off-road, closed-course competition, or agricultural use only. It is illegal to use these products on public highways or street-registered vehicles. Buyers must verify and comply with all local, state, and federal emissions laws prior to purchasing.

What delete kit fits a 2020 Ram 2500 6.7L diesel?

Fitment depends on the exact kit, exhaust layout, and tuning plan. For a 2020 Ram 2500 6.7L diesel, check whether the product is listed for 5th Gen Ram trucks and confirm pickup vs. cab/chassis compatibility before ordering.

Does a Ram 6.7L diesel delete kit need a tuner?

Yes. Delete hardware requires proper off-road tuning sourced separately. Without the correct tuning, the truck may trigger emissions-related codes, limp mode, regen issues, or DEF warning messages.

What is the difference between DPF, DEF, EGR, and CCV components?

DPF components relate to the diesel particulate filter in the exhaust, DEF/SCR components relate to diesel exhaust fluid treatment, EGR components recirculate exhaust gas back into the intake, and CCV reroute components manage crankcase ventilation. Not every kit includes every component, so always check the selected product package.

Ram 6.7L Diesel Delete Kits for 2500/3500 Trucks

Looking for delete kit options for your Ram 2500 or Ram 3500 with a 6.7L diesel engine? SPELAB offers all-in-one and standalone delete components for select Ram 6.7L diesel trucks. Available configurations may include DPF, DEF, EGR, and CCV reroute components depending on the kit selected. These parts are designed for off-road, closed-course, competition, or agricultural use where permitted.

Choose the Right Delete Kit Setup for Your Ram

SPELAB offers a range of Dodge Ram 6.7L diesel delete kit configurations to suit every kind of truck owner—from basic EGR delete kits to complete DPF/DEF/EGR/CCV all-in-one delete solutions, as well as advanced options like the Intake Manifold + Grid Heater Delete. All kits are precisely engineered for 2007–2021 Ram 2500 and Ram 3500 models equipped with the 6.7L diesel engine.

The All-in-One Kit is our most popular setup, including a high-flow race pipe, CNC block-off plates, a coolant reroute hose, and a CCV reroute cap. When paired with mandatory custom off-road tuning, sourced separately, the right hardware setup can support improved drivability, reduced emissions-system related issues, and smoother throttle response. Owners of the 6.7L inline-6 diesel report noticeably reduced turbo lag, a 10–15% drop in Exhaust Gas Temperatures (EGTs), and smoother throttle response while towing.

For drivers upgrading in phases, SPELAB also offers standalone delete components, including EGR-only or DPF-only delete kits. Advanced users can take it further with the intake manifold and grid heater delete, designed to improve airflow, reduce intake temps, and maximize combustion efficiency.

Ram 6.7L Diesel Delete Kit Fitment by Model Year

Fitment varies by model year, truck configuration, and the specific kit selected. Before ordering, confirm your Ram 2500 or Ram 3500 model year, pickup vs. cab/chassis configuration, exhaust layout, and required tuning support.

Use the guide below as a starting point when comparing available SPELAB delete kit options:

Model Year	Common Truck Fitment	What to Check Before Ordering
2007.5–2012	Ram 2500/3500 6.7L diesel	DPF/EGR layout, pickup vs. cab/chassis, exhaust size
2013–2018	Ram 2500/3500 6.7L diesel with DEF/SCR system	DEF/SCR components, EGR layout, tuning requirements
2019–2024	5th Gen Ram 2500/3500 6.7L diesel	Updated emissions layout, engine bay changes, kit-specific fitment

Our kits are thoroughly tested for compatibility across all drivetrain configurations, including the 68RFE automatic, Aisin AS69RC heavy-duty automatic, and G56 manual transmissions, as well as both Single Rear Wheel (SRW) and Dual Rear Wheel (DRW) setups. Most kits are designed as direct-fit hardware, but installation requirements can vary by year, configuration, and supporting tuning setup.

Custom Tuning Required: Maximize Reliability and Power

Hardware is only half the equation. To successfully install a SPELAB delete kit on your 6.7L inline-6 diesel, your truck’s Engine Control Module (ECM) must be recalibrated with custom delete tuning (via platforms like EZ Lynk, MM3, or specialized programmers).

Running a delete kit without proper tuning will result in a dashboard full of Diagnostic Trouble Codes (DTCs), a vehicle stuck in "Limp Mode," or the dreaded "DEF See Dealer" countdown. A proper delete tune works alongside our hardware to:

Disable emissions sensors: Electronically shuts off the EGR, DPF, and DEF systems so the truck no longer searches for them.
Stop regeneration cycles: Completely halts active and passive exhaust regen, saving fuel and preventing diesel fuel from washing down the cylinder walls.
Optimize VGT mapping: Adjusts the Variable Geometry Turbo vanes to improve exhaust flow, lower Exhaust Gas Temperatures (EGTs), and prevent common turbo codes like P2262.

With the right hardware and off-road tuning setup, drivers may notice better throttle response, reduced exhaust restriction, fewer regen-related interruptions, and improved drivability under load. Actual horsepower, torque, EGT, and fuel economy results vary based on tune files, truck condition, tire size, gearing, load weight, and driving style.

⚠️ WARNING: All SPELAB DPF, DEF, and EGR delete kits are strictly intended for off-road, closed-course competition, or agricultural use only. It is the buyer's responsibility to verify and comply with all local, state, and federal emissions laws prior to purchase and installation.

Why Choose SPELAB for Your Ram 6.7L Diesel Deletes?

The aftermarket is flooded with cheap, poorly manufactured delete pipes that warp, leak, and crack under pressure. At SPELAB, we focus on fitment, sealing, material strength, and installation completeness, because heavy-duty diesel owners need hardware that can handle heat, vibration, towing, and long-term use.

Here is why thousands of heavy-duty truck owners trust SPELAB:
