Industrial Injection 04.5-06 Chevrolet LLY Duramax Stock Street Long Block

This Industrial Injection Stock Street Long Block is built for your 2004-2005 Chevrolet Silverado 2500 HD or GMC Sierra 2500 HD with the LLY Duramax engine. What you get is a fully assembled engine, ready to be installed. This isn't just a bare block; it's a complete foundation for your diesel truck's power, featuring a well-built rotating assembly, cylinder heads, and the critical internal components that make up a long block. It's designed to get your truck back on the road with the dependable performance you expect from a Duramax.

Industrial Injection has put together this long block with a focus on durability and street-friendly operation. The components inside are selected to handle the demands of daily driving and towing, offering an improved option over a worn-out original engine. This build aims for a balance between robust construction and the smooth operation needed for everyday use. It’s a solid choice if you’re looking to replace a failed engine or want to build a more reliable foundation for your truck’s powertrain.

When installing this long block, remember that it's a substantial component. You'll need to transfer many of your existing external accessories and components onto the new engine, such as the fuel system, turbocharger, and intake manifold. It's crucial to ensure all connections are clean and properly sealed during the swap to prevent leaks and ensure optimal performance. This long block is a significant step towards restoring or enhancing your LLY Duramax's performance and reliability.
