Ram 6.7 Cummins Cab & Chassis full delete kit with EZ Lynk Auto Agent 3 (2011-2021)
The 2011-2021 Ram 6.7 Cummins Cab & Chassis Delete Kit with EZ Lynk Auto Agent 3 is designed to optimize your truck's performance by removing DPF and EGR systems. This complete 6.7 Cummins delete kit with tuner enhances power, fuel efficiency, and engine reliability, specifically for off-road use.
What's included in delete kit
-
EZ Lynk Auto Agent 3 - Connects to the truck through the OBD-II port and communicates with the EZ Lynk cloud through a smartphone. The device supports wireless tune delivery, data logging, live diagnostics, and diagnostic-code reading.
-
Custom Delete Calibration - Matches the exact model year, Cab & Chassis ECM, and Aisin transmission configuration. Available power levels and SOTF capability depend on the resolved year-specific tune.
-
EGR Valve and Cooler Delete Kit - Removes the EGR valve and cooler circuit from operation, stopping exhaust recirculation through the deleted path.
-
Aluminum Block-Off Components - Seal the EGR connections after the valve and cooler hardware are removed.
-
Installation Hardware - Application-specific clamps and fasteners secure the selected exhaust and EGR components.
Selectable Options:
-
DPF Delete Pipe - Replaces the factory particulate-filter section while retaining more of the original exhaust routing.
-
DPF Delete Pipe With Muffler - Adds a muffler to reduce exhaust volume and cab resonance.
-
5-inch Exhaust System - Uses larger stainless steel tubing for a deeper, more aggressive exhaust sound.
-
5-inch Exhaust System With Muffler - Combines the larger exhaust diameter with additional sound control.

Option |
Choice |
Recommended for |
|---|---|---|
|
Model Year |
2011-2012 |
Choose for 2011-2012 Ram 6.7L Cummins Cab & Chassis trucks. These models use the AS68RC transmission. |
|

Choose for 2013-2017 Cab & Chassis trucks with the later AS69RC transmission and standard programming connection. |
|
|
2018 |
Choose specifically for 2018 trucks. This model year uses the AS69RC transmission and requires the applicable security-bypass procedure for programming access. |
|
|
2019-2021 |
Choose for 2019-2021 Cab & Chassis trucks with the AS69RC transmission and the required security-bypass programming workflow. |
|
|
Exhaust Option |
DPF Delete Pipe |
Best if you want to replace only the factory filter section while retaining more of the original exhaust routing. |
|
Delete Pipe w/ Muffler |
Best if you want the simpler delete-pipe configuration with reduced exhaust volume and resonance. |
|
|
5-inch System |
Best if you want a larger full exhaust configuration with a deeper, more aggressive sound. |
|
|
5-inch System w/ Muffler |
Best if you want the larger 5-inch exhaust while keeping sound and cab resonance more controlled. |
How the delete kit works on your 6.7 Cummins
-
Downloads the correct custom tune through the EZ Lynk cloud.
-
Programs the ECM through the truckβs OBD-II connection.
-
Replaces the restrictive DPF and SCR exhaust section.
-
Stops regeneration, DEF dosing, and EGR recirculation.
-
Provides smartphone monitoring, logging, and live diagnostics.
The 6.7 Cummins tuner coordinates the electronic calibration with the physical DPF delete and EGR hardware. Year-specific programming prevents the ECM from continuing to command the removed emissions components.
Installation information
This 6.7L Cummins delete kit comes with step-by-step installation instructions, so if you have basic mechanical skills, you can complete the installation yourself. Professional installation is also an option for those who prefer to leave the job to an experienced technician.
