Understanding Durango Engine Swap Compatibility
Engine swaps in a Dodge Durango involve balancing physical fit, mounting points, electronic integration, and drivetrain compatibility. Not all engines are plug-and-play; careful planning is essential.
Why Compatibility Matters
When swapping an engine, you must consider:
- Physical fitment – Does the engine fit in the engine bay?
- Mounting points – Can it be bolted to the chassis without custom mounts?
- Electronics – Will the engine communicate properly with the vehicle’s PCM?
- Transmission compatibility – Will the existing transmission handle the engine?
- Accessories – Alternator, AC, power steering, and exhaust alignment.
The chart above provides a guideline, but custom work may still be needed for electronics, exhaust, or accessory placement.

Common Swaps by Durango Generation
First Generation (1998–2003)
First-gen Durangos often came with 5.2L or 5.9L V8 engines. Common swaps include:
- 4.7L PowerTech V8 – lighter, more efficient, similar bolt-in points.
- 5.7L HEMI (Gen1) – fits with PCM and wiring adaptations.
- 5.9L Magnum V8 – easiest swap within the same engine family.
Older swaps focus more on mechanical adjustments than electronics.
Second & Third Generation (2004–2010 / 2011–2020)
Engines include 4.7L V8, 3.7L V6, 5.7L HEMI, and 6.1L SRT8. Common swaps:
- 4.7L to 5.7L HEMI – bolt-in possible; PCM and wiring modifications required.
- 6.1L SRT8 – performance upgrade; may need transmission, cooling, and driveline upgrades.
- 6.4L HEMI (392) – fits with minor exhaust and wiring modifications.
Electronics become more important in these generations.

Fourth Generation (2011–Present)
Engines include 3.6L Pentastar V6, 5.7L HEMI, 6.4L HEMI, and 6.2L Supercharged Hellcat. Key points:
- 3.6L to 5.7L or 6.4L HEMI swaps – require PCM and wiring harness updates.
- 6.2L Hellcat – extreme torque requires upgraded transmission, driveline, and cooling systems.
- Electronics dominate modern swaps; a donor harness or aftermarket engine management is often required.
Transmission and Drivetrain Considerations
Swapping larger engines, such as 6.4L or 6.2L, requires attention to:
- Transmission capacity
- Driveshaft length and compatibility
- Axle and differential upgrades
- Cooling system capacity
Even if the engine physically fits, the supporting components must handle the added torque and power.

Electronic Integration
Modern Durango swaps are heavily influenced by electronics:
- PCM (engine computer) must support the engine.
- Wiring harnesses may need modification or replacement.
- Sensors for crank, cam, emissions, and throttle control must be compatible.
For example, the 5.7L HEMI has two broad generations; swapping across them requires adjustments due to variable valve timing and sensor differences.
Final Thoughts
Engine swaps in a Dodge Durango are feasible from mild upgrades to high-performance builds. Key takeaways:
- Use a compatibility chart as a foundation.
- Plan for electronics and PCM integration early.
- Budget for transmission, drivetrain, and cooling upgrades.
- Research forums and build logs for your specific year and engine.
With careful planning and execution, engine swaps can transform your Durango into a reliable daily driver or high-performance machine.
