What Is a Ram Cummins Delete Kit?
If your truck is stuck in regen cycles, losing power, or throwing emissions codes, you’re not alone. The factory emissions system on the 6.7 Cummins—DPF, DEF, and EGR—can become a restriction point over time.
A Ram Cummins delete kit removes or replaces these components and pairs them with proper tuning so your engine runs clean, consistent, and predictable again.
An all-in-one delete kit takes it further by bundling everything you need into one package:
- DPF delete solution
- DEF system removal components
- EGR delete hardware
- Tuning (required for proper operation)
- Supporting pipes, plugs, and hardware
Instead of mixing parts from different sources, you get a system that’s designed to work together.
Why 6.7 Cummins Owners Choose Delete Kits
Most Cummins owners don’t start here—they end up here after dealing with ongoing issues.
Common Problems:
- Constant regen cycles killing fuel economy
- Plugged DPF causing power loss
- DEF system failures (especially in cold climates)
- EGR soot buildup restricting airflow
What a Cummins Delete Kit Solves:
- Reduces exhaust restriction and backpressure
- Improves throttle response and drivability
- Simplifies engine systems (fewer failure points)
- Helps stabilize engine temps under load
What Does a 6.7 Cummins Delete Kit Include?
Delete Pipes
-Replaces the restrictive DPF/catalytic section with a free-flowing pipe.
EGR Delete Components
-Block-off plates and reroute hardware to remove exhaust recirculation.
Tuning Device + Files
-This is critical. Without tuning, your truck will not run correctly after removing emissions components.
Sensors / Plugs / Hardware
-Everything needed to complete the install cleanly without chasing extra parts.
