LLY Duramax Parts

One of the biggest differences between the LLY and its predecessor, the LB7, is that the LLY is fitted with emissions controlling technology. Now equipped with a faster spooling Turbocharger which created more torque sooner with less emissions. Powerhouse Diesel has a huge selection of LLY Duramax parts to help you boost its performance, extend its lifespan and ensure it remains in good working order for as long as possible.
