Industrial Injection 00-04 Chevrolet LB7 Duramax Race Performance Long Block (R/R Only)

When you're looking to rebuild or significantly upgrade the heart of your 2011-2016 Chevrolet Silverado 2500 HD or 3500 HD, or your 2011-2016 GMC Sierra 2500 HD or 3500 HD, this Industrial Injection Race Performance Long Block is a solid foundation. This isn't just a standard replacement; it's a fully assembled engine ready to handle more power and demanding use. It's designed for those who push their Duramax LB7 engines beyond factory limits, offering a robust starting point for a high-performance build.

This long block comes as a complete, ready-to-install unit, meaning the cylinder heads, block, crankshaft, connecting rods, and pistons are all assembled and balanced. Industrial Injection uses well-built components throughout to ensure reliability under stress. The focus here is on performance and durability, providing an improved airflow path and stronger internal components compared to stock. This unit is built for 'R/R Only,' meaning it's designed for a direct replacement installation where you'll transfer your existing accessories and external components onto this new long block.

Because this is a performance-oriented engine, it's crucial to ensure your supporting systems are up to the task. This includes fuel delivery, cooling, and exhaust. While this long block is a significant upgrade, it's important to note that it is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation guide for specific details on transferring your existing components and any recommended break-in procedures.
