Doing an engine rebuild? Get superior quality and the increased combustion seal strength that fire rings give with Industrial Injection's Premium Stock Plus Cylinder Head. Upgrade the durability and sealing capability of your diesel engine with the Industrial Injection 6.7L Cummins Stock Cylinder Head with Fire Rings. Designed for Ram 2500 and 3500 trucks equipped with the 6.7L Cummins engine, this performance-ready cylinder head is built to handle increased cylinder pressure and boost levels while maintaining factory-style reliability.

NOTE: Fire Ring Gasket sold separately. Installation of a fire ring gasket requires high yield head studs to ensure proper seat of the head to the cylinder block.

This head is precision-machined with fire ring grooves to provide superior combustion sealing in high-performance and heavy towing applications. Combined with upgraded valvetrain components and precision machining, it delivers improved durability compared to a standard stock replacement cylinder head.
