Direct-Fit Crate Engine for 5.9L Cummins

When your 5.9L Cummins starts showing signs of wear—low compression, excessive blow-by, or internal damage—you have a choice to make. Rebuilding a worn-out engine can be time-consuming, costly, and full of unknowns. That’s why a fully assembled long block like the BD Diesel Precision Plus is a smart solution. It eliminates the guesswork, delivering a high-quality replacement engine that’s been built from the ground up to exceed OEM standards. Whether you’re restoring a high-mileage workhorse or looking for a fresh start before adding more power, this long block is designed to provide durability, reliability, and easy installation. Every Precision Plus long block starts with precision CNC machining to ensure exact tolerances. The block is fully blueprinted, bored, honed, and deck-surfaced for optimal strength and longevity. This process eliminates inconsistencies that can lead to performance issues, giving you a solid foundation built to handle the demands of daily driving, heavy towing, or performance upgrades.

High-Quality Construction with Brand-New Components

The included cylinder head is a significant improvement over stock. It features heavy-duty bronze valve guides and oversized hardened valve seats, which reduce wear and prevent common failures seen in factory heads. A CNC-machined high-performance valve job optimizes airflow, improving efficiency and power delivery. Whether your truck is stock or tuned, this upgraded head ensures better combustion and overall engine performance. Inside the engine, all components are brand new, eliminating the risks associated with used or questionable rebuilds. The long block includes new pistons, bearings, tappets, an oil cooler, and an oil pump, ensuring that every critical moving part is built for longevity. Pre-lubed with break-in oil, this engine is ready for installation and first startup right out of the crate.

Drop-In Installation

For ease of installation, the Precision Plus long block comes fully assembled with an oil pan and front timing cover already in place. This makes it a direct replacement for 2004.5-2007 Dodge Ram 5.9L Cummins trucks, simplifying the swap and reducing downtime. Rated for up to 700 horsepower, this engine provides a strong and reliable base for stock and lightly modified applications. While aggressive high-horsepower tuning isn’t recommended for heavy towing, this engine is more than capable of handling the demands of daily driving, worksite hauling, and performance enthusiasts looking for a dependable upgrade.
