Industrial Injection 89-98 Dodge Cummins 5.9L 12V Premium Stock Plus Head w/Fire Rings

This Premium Stock Plus cylinder head from Industrial Injection is built for the 1989-1998 Dodge Cummins 5.9L 12V engine, featuring integrated fire rings. These fire rings are a key design choice, creating a stronger seal between the cylinder head and the engine block. This is especially important for engines that see higher cylinder pressures, helping to prevent head gasket leaks and maintain consistent compression. The head itself is a well-built component designed to meet or exceed the performance of the original equipment, offering a solid upgrade for your Cummins.

Industrial Injection has put this head together with durability and performance in mind. The fire ring design is a notable improvement over standard head gaskets, providing a more robust sealing surface that can handle increased boost and combustion forces. This makes it a popular choice for Cummins owners looking to improve the reliability and performance of their 12-valve engine, whether for daily driving, towing, or more demanding applications. The head is designed as a direct replacement for your stock unit, simplifying the installation process for experienced mechanics.

When installing this cylinder head, it's crucial to follow the manufacturer's recommended procedures for proper torque sequencing and gasket installation to ensure the fire rings seat correctly and provide the intended seal. This head is a significant upgrade for your 5.9L 12V Cummins, offering enhanced sealing and reliability for your engine build.
