Industrial Injection 04.5-05 Chevrolet Duramax 6.6L LLY Stock Long Block Engine

If your 2004.5-2005 Chevrolet Duramax 6.6L LLY engine has seen better days and you're looking for a solid replacement, this Industrial Injection stock long block is a well-built option. It's designed to get your truck back on the road with a reliable foundation. This isn't just a collection of parts; it's a fully assembled engine ready to be installed, saving you significant time and labor compared to rebuilding your old one piece by piece.

Industrial Injection has put together this long block using a combination of new and remanufactured components to meet factory specifications. The block itself is a critical piece, and this unit is built to the original dimensions and tolerances. It includes the cylinder block, crankshaft, connecting rods, pistons, piston rings, main bearings, rod bearings, and camshaft. All these core rotating and reciprocating assemblies are carefully selected and put together to ensure proper function and longevity. This approach means you're getting a complete, ready-to-go engine that minimizes the guesswork and potential for error during installation. It’s a practical solution for bringing your Duramax back to life.

When you're ready to install, you'll transfer your existing cylinder heads, intake and exhaust manifolds, fuel system, and accessories onto this new long block. This makes the swap more straightforward, as you're not dealing with the complexity of those external systems. It’s important to note that this engine is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for the most accurate guidance on the swap process and any specific requirements for your vehicle.
