07.5-10 Duramax LMM

GM Duramax LMM

Nearly identical to the LBZ, the LMM debuted midway into the 2007 model year (2007.5). The slight variations between the LBZ and LMM gave the LMM a small boost in power output. The LMM features new emissions equipment that meet strict new diesel emission laws, and is currently in production today. Using a diesel particulate filter (DPF) and active regeneration technology, the LMM cut particulate matter emissions by 90 percent over the previous generation.
