About this part

Product Details

When you're looking to replace the heart of your 2011-2016 Chevrolet Silverado 2500 HD or 3500 HD, or its GMC Sierra counterparts, this Industrial Injection Premium Stock Plus Long Block Engine is a solid choice. This isn't just a basic rebuild; it's a fully assembled long block that includes the engine block, cylinder heads, crankshaft, pistons, connecting rods, and camshaft. It's built to be a direct replacement for your Duramax 6.6L LML engine, aiming to get you back on the road with a well-built, reliable powerplant.

Industrial Injection takes a well-built stock engine and enhances it for improved durability and performance, earning it the 'Stock Plus' designation. This means they use quality components and machining processes to ensure the engine can handle more than just daily driving. The focus here is on creating a strong foundation for your truck's power needs, whether for towing, hauling, or just dependable daily use. They pay attention to the critical internal components, ensuring they meet or exceed original specifications for longevity.

This long block engine is designed as a complete unit, simplifying the installation process compared to sourcing individual parts. It comes ready to have your existing accessories, like the fuel system, turbocharger, and intake/exhaust manifolds, bolted on. Keep in mind that this engine is not CARB approved and cannot be shipped to California. For a complete installation, you'll want to refer to the manufacturer's detailed instructions and ensure all supporting systems are in good working order.
