The result is a fully refreshed Duramax powertrain package that restores factory performance while adding durability improvements ideal for towing, daily driving, fleet trucks, and work vehicles.
Why This LML Duramax Engine Package Is Better
The LML Duramax platform is a strong engine, but several components have proven to be weak points over time. This package addresses those areas during engine replacement.
Eliminates the CP4 Fuel Pump Failure Risk
The factory CP4 pump used in the LML Duramax has been known to fail and contaminate the entire fuel system. This package converts the truck to the highly reliable Bosch CP3 injection pump.
Improves Engine Cooling
The Banks upgraded oil cooler system reduces oil temperature by up to 31%, helping protect the engine during towing and high-load driving.
Restores Factory Power and Efficiency
Genuine Bosch injectors and Garrett turbocharger ensure your engine performs exactly as GM intended.
Improves Exhaust Flow and Durability
The BD upgraded exhaust manifolds increase flow and eliminate cracking issues common with factory manifolds.
