Do you want to rebuild your Cummins with something that can handle serious power and be reliable? This Long Block from D&J Precision Machine is designed for people who are pushing their trucks harder than stock is meant to handle. This isn’t your typical reman engine; it’s a fully upgraded long block built to handle higher horsepower, heavier loads, and the kind of stress that comes with towing, tuning, and real-world diesel use.

From the moment it’s installed, this setup delivers a stronger, more stable foundation with improved airflow, better valvetrain control, and the durability to withstand boost. It’s built for trucks that work, tow, and have added power, giving you confidence that your engine can take what you throw at it. If you’re tired of worrying about weak links, this is the kind of engine that lets you actually use your truck the way it was meant to be used.

Each HP Reman Extreme long block starts as a fully disassembled core that’s crack-checked, cleaned, and precision-machined using CNC blueprinting processes to restore and optimize all critical tolerances. The block is bored, honed, and decked, while rotating assembly components are measured and corrected to ensure proper clearances and long-term durability.

What sets this package apart is the performance-focused build strategy. These engines are fully assembled from the oil pan up and include upgraded internal components and airflow improvements designed to handle increased cylinder pressure and boost.

Assembly is completed using high-quality components and strict quality control standards, pre-lubed and checked before delivery, ensuring readiness out of the box. The result is a long block that delivers improved strength, better airflow, and the reliability needed for high-demand diesel applications, making it a serious step up from a standard reman engine.

A sock with real support and thickness!
Size: Large, Color: (001) Black / Black / Pitch Gray
I’m pretty happy with these. It seems like sock manufacturing changed 10-15 years ago, and it’s become hard to find pairs that are actually thick and durable. I bought these for an event where I knew I’d be on my feet all day, and they did not disappoint. They provided excellent support throughout the day, even while wearing shoes that typically make my feet ache after just a couple of hours. Glad to finally find a pair that feels well-made.
