The diesel world has been buzzing with rumors for a while, but it’s finally official: Dodge is officially moving forward with a massive 7.2L Cummins diesel platform slated for the 2027 model year. For those of us who live and breathe heavy-duty trucks, this is the kind of news that changes the game. This isn’t just a minor tweak; it’s a significant displacement jump that signals Dodge’s commitment to internal combustion in an increasingly electric-focused market.
The 7.2L Cummins: Bigger Displacement, Familiar Architecture
While the jump to 7.2 liters is a headline-grabber, the architecture under the hood might feel surprisingly familiar. Dodge has confirmed that the 2027 Cummins will continue to utilize a modular emissions strategy. This means you’ll still see the “big three” components:
- Exhaust Gas Recirculation (EGR)
- Diesel Particulate Filter (DPF)
- Diesel Exhaust Fluid (DEF)
The good news for shops and enthusiasts is that these systems will remain modular and bolt-on, much like the current 6.7L Cummins platform. Continuity is key here, and with AP Emissions Technologies remaining the primary manufacturer for these components, we can expect a relatively stable transition in terms of hardware reliability and replacement parts.

A Shift in Emissions Strategy: Rethinking Limp Mode
One of the most interesting revelations regarding the 2027 Dodge trucks is how they plan to handle DEF-related fault conditions. We’ve all been there—a sensor acts up or you’re in the middle of nowhere without a DEF pump in sight, and suddenly your truck threatens to crawl at 5 mph.
Dodge is implementing a new ECM programming requirement for dealers that allows for an extended engine runtime during certain DEF events. Instead of an immediate, aggressive limp mode, the vehicle can be programmed to allow a predetermined mileage threshold. It’s a pragmatic move that balances strict emissions regulations with the real-world needs of drivers operating in remote or supply-constrained environments.
ECM Supply Chain News: 2019–2021 Owners Take Note
If you’ve been struggling to find a replacement ECM (Engine Control Module) for your 2019–2021 Dodge Cummins, there’s finally light at the end of the tunnel. After a three-month manufacturing hiatus, production is scheduled to resume on March 1.
However, there is a catch: ECM motherboards will no longer be sold as individual units. Moving forward, only complete ECM assemblies will be distributed. Furthermore, Dodge is tightening the reins on distribution, limiting access to these units primarily to dealers and authorized aftermarket companies like Summit Racing. If you’re planning a build or a repair, staying ahead of these supply chain shifts is crucial.
