This Industrial Injection performance short block starts with a robust foundation, featuring a block that's been meticulously prepared and assembled. It's built to handle more power than the stock engine, making it a solid choice if you're looking to upgrade your 2011-2016 Chevrolet Silverado 2500 HD or 3500 HD, or your 2011-2016 GMC Sierra 2500 HD or 3500 HD. This isn't just a replacement; it's a significant step up for those pushing their Duramax LML engines beyond factory limits.

Inside this short block, you'll find carefully selected components designed for longevity under increased stress. While it comes without cylinder heads, the core rotating assembly and block are prepared to accept performance modifications. This means you can pair it with your choice of heads and other components to tailor your engine's power output and characteristics. The assembly process at Industrial Injection focuses on precision, ensuring that each part is seated and balanced correctly for smooth operation and reliable performance, even when you're asking a lot from your truck.

When considering a performance short block like this, remember it's a major component for a complete engine build or rebuild.

This Industrial Injection short block is designed for trucks that see demanding use, whether for heavy towing, competitive pulling, or simply seeking a more capable daily driver.
