The LMM was the 2007.5-2010 6.6L Duramax, the first to add a diesel particulate filter (DPF) for emissions compliance. We carry OEM-brand LMM parts - fuel injectors, CP3 injection pumps, turbochargers, DPF and emissions components, and related fuel-system and engine parts - many with no core charge and fast US shipping. Because Duramax parts vary by generation, verify the part against your LMM by OEM cross-reference before ordering.
