Industrial Injection Fire Ring Head Gasket Kit Cummins 6.7L (2007.5-2018)

The Industrial Injection Fire Ring Head Gasket Kit for the 2007.5–2018 Cummins 6.7L platform is designed for high cylinder pressure environments where a traditional MLS gasket alone may not provide sufficient sealing. This configuration uses precision fire rings combined with a high-quality head gasket to provide controlled combustion sealing when the cylinder head has been properly machined.

The Industrial Injection Fire Ring Head Gasket Kit Cummins 6.7L (2007.5-2018) is supplied for machine shop installation and includes the fire rings and gasket required once the cylinder head has been cut to accept the ring grooves.

System Design

Fire Ring Sealing Method

The fire ring system creates a concentrated sealing surface around each cylinder bore once the grooves are machined into the cylinder head. This approach helps control combustion sealing in high cylinder pressure environments where additional sealing control is required.

Machine Shop Installation

This kit is intended to be installed after the cylinder head has been machined to accept the fire ring grooves. Installation instructions are included to guide the machining and assembly process.

Installation Requirements

• Factory head bolts must not be used with this configuration.
• Proper cylinder head machining is required prior to installation.
• This kit can also be used with compatible cylinder heads that already have fire ring grooves machined.
