LML Duramax Parts

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. Powerhouse Diesel has a huge selection of LML Duramax parts to help you boost its performance, extend its lifespan and ensure it remains in good working order for as long as possible
