D&J Precision Plus Short Block Engine 07.5-18 Ram 6.7L Cummins
Is it time to completely refresh your Cummins and get it running reliably again? The Precision Plus Short Block from D&J is built for those who want more than just a basic replacement. It’s about restoring confidence in your block with tighter tolerances, improved consistency, and a stronger overall foundation than a typical remanufactured engine. Instead of taking chances on worn-out cores or inconsistent machine work, you’re starting fresh with a professionally built assembly designed to maintain compression, control oil, and stay dependable under real-world workload.
This setup is ideal for daily driving and towing, while providing the precision needed for long-term durability and future upgrades. It also comes with the oil pan, oil cooler housing, and timing cover pre-installed, helping simplify installation and save time when it’s dropped into the truck. Whether your original engine has already failed or you’re getting ahead of it, this short block provides a solid, reliable foundation that removes the common weak points found in high-mileage 6.7L platforms.
Each Precision Plus short block is fully remanufactured and CNC blueprinted, with machining processes including boring, honing, and surfacing to restore all critical tolerances to OEM specifications. Every component is thoroughly inspected for cracks, wear, and dimensional accuracy, with key measurements like bearing clearances, piston-to-wall clearance, piston protrusion, and ring gaps carefully verified to ensure proper balance and performance.
Final assembly takes place in a clean-room environment by skilled technicians using new internal components, ensuring consistent quality and long-term durability. The end result is a short block that offers improved precision, better oil control, and dependable performance under load.
