KNOW YOUR TRUCK
Is it an LMM? It changes the parts.

LBZ (VIN 8th digit “D”)
- 360 hp / 650 lb-ft
- No DPF
- Older body style
- See the LLY & LBZ guide →
LMM (VIN 8th digit “6”)
- 365 hp / 660 lb-ft
- First Duramax with a DPF
- Larger EGR cooler
- Allison 1000 6-speed
- New body style (GMT900)

LMM Duramax performance questions, answered.
Can I add power and keep my DPF?
Yes. We install emissions-legal tuning and parts that work with the factory DPF and EGR.
Will more power hurt my Allison?
It can. We match power to the transmission and add cooling, or rebuild it with heavy-duty parts if you want more.
Do you install at my location?
