Reman Cylinder Head Dodge/Ram 5.9L Cummins 2003-2007

[shortdesc]

This Cylinder Head is engineered to address common failures in stock and aftermarket heads, making it a reliable upgrade for both stock and performance applications. One of the biggest factory issues is valve seat failure, which can lead to catastrophic engine damage. This remanufactured head features upgraded, heat-resistant valve seats, precision machining, and genuine Cummins valves to ensure long-term durability and performance. Built for 2003-2007 Dodge Ram 2500 & 3500 trucks, this reman head is completely disassembled, crack-checked, CNC-machined, resurfaced, and assembled with new components. Manufactured by D&J Precision Machine, this cylinder head provides superior reliability and efficiency for high-performance and daily-driven Cummins builds.

• Upgraded Valve Seats - Taller and larger diameter than stock, made from a heat-resistant alloy to prevent loosening and failure
• Improved Heat Dissipation - Larger seats dissipate heat more efficiently, reducing cracking risks
