Are you building a high-power 5.9L Cummins while keeping it reliable? The Street Performance Long Block from D&J Precision Machine is built for exactly that. This is where reliability meets real horsepower, giving you a fully assembled engine that’s ready to handle serious boost, aggressive tuning, and heavy load without becoming the weak link in your build.
This isn’t a basic crate engine; it’s a purpose-built setup designed for trucks that tow, race, or are running high-power mods. With upgraded internals and airflow improvements, it delivers stronger power potential, better throttle response, and the kind of durability you need when you’re pushing beyond stock limits. If you want a long block that can support big power while still being street-driven, this is that balance: strong, capable, and built to be used.
At the core of this build is a fully assembled long block, designed from the ground up with performance in mind. It comes complete from the oil pan up, including critical components like the front cover and seals, helping streamline installation and ensure consistency right out of the crate.
What sets this engine apart is the hardware inside. It features X-beam billet connecting rods, a high-flow Stage 1 cylinder head, and fire-ring sealing with upgraded head studs, all designed to handle significantly higher cylinder pressure and boost levels than stock. These upgrades work together to improve airflow, strengthen the rotating assembly, and maintain head sealing under extreme conditions.
The result is a long block built for durability, airflow, and high-performance reliability capable of supporting serious horsepower while maintaining the strength needed for real-world diesel use.
