Industrial Injection 06-07.5 Chevrolet LBZ Duramax Performance Short Block ( No Heads )

If you're looking to build a seriously powerful Duramax diesel, starting with a robust short block is key. This Industrial Injection performance short block is designed for the 2006-2007 Chevrolet Silverado 2500 HD, 3500 HD, and GMC Sierra 2500 HD, 3500 HD models equipped with the LBZ engine. It serves as the foundation for a high-output engine build, ready to handle increased power demands whether you're towing heavy loads or competing in diesel events.

Industrial Injection has put together a well-built short block that starts with a strong foundation. This unit includes a fully machined block, a forged crankshaft, and forged connecting rods, all balanced to work together smoothly. The pistons are also forged, designed to withstand higher cylinder pressures and temperatures. This combination of strong internal components is crucial for reliability when you're pushing an LBZ engine beyond its stock capabilities. It's important to note that this is a short block assembly, meaning it comes without cylinder heads, camshaft, or valvetrain components, allowing you to customize those parts to your specific build goals.

When undertaking a performance engine build of this magnitude, careful planning is essential. This short block is intended for custom applications where significant power increases are desired. You'll need to source compatible cylinder heads, injectors, turbochargers, and a fuel system to complete the engine. Remember, this assembly is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's detailed build specifications and recommended installation procedures to ensure the longevity and performance of your new engine.
