D&J Reman Cylinder Head 03-07 Ram 2500/3500 5.9L Cummins
Looking for a reliable replacement for your 5.9L Cummins cylinder head? The D&J Precision Machine Reman Cylinder Head is engineered to solve common factory failures, like valve seat cracking and soft plug issues, helping protect your engine from costly damage!
What sets this remanufactured cylinder head apart is its combination of upgraded, heat-resistant valve seats, genuine OEM Cummins valves, and precision CNC machining. Taller, larger-diameter valve seats improve heat dissipation and reduce the risk of failure, while thread-in soft plugs eliminate the weakness of stock plugs. Each head is fully disassembled, crack-checked, resurfaced, pressure-tested, and assembled with new bronze guides, hardened seats, and valve seals for long-lasting performance.
Designed for durability and efficiency, this cylinder head is built for both stock and performance applications. It is carefully machined and assembled to ensure consistent operation, providing a dependable solution for daily-driven trucks or high-performance Cummins builds.
