BUILT FOR PERFORMANCE

The LML Engine once again came with new revisions, not only to satisfy emissions standards but to further efficiency and power gains. Equipped a “9th injector” fuel system configuration, this accommodation was made to provide fuel during the DPF regeneration process. Other upgrades to pistons, heads and turbocharger were made.

Here at Powerhouse Diesel, our inventory of LML duramax performance parts and accessories includes just about everything you could need. We have a huge range of options from many of the top manufacturers in the industry, including Fleece, Kryptonite, DDP and Rough Country.
