With independently verified tensile strength over 288,000 PSI and yield strength over 254,000 PSI, these high-yield studs give Cummins engine builders the clamping force needed to keep head gaskets sealed under sustained boost. Each stud is heat-treated, centerless-ground for accuracy, and thread-rolled to Mil-S-8879 spec.

• Built to meet high-performance and extreme-performance applications
• Tensile strength exceeding 288,000 PSI
• Enhanced cylinder head clamping force
• Heat treated before thread rolling
• Manufactured to top-level standards, including EDM broaching

For engine builders who demand the highest level of strength and precision in their fasteners, the PPE High Yield Head Stud Kit is the ultimate solution for high-performance diesel engines.

With an independently tested and verified tensile strength of over 288,000 PSI, and yield strength over 254,000 psi, these studs simply outperform any competition out there. Each stud is heat treated before being centerless ground and thread rolled, which effectively reduces stress concentration and results in a much higher fatigue resistance. Broaching of studs is performed via EDM to ensure top-level precision. All studs and nuts come with a oxide finish.

Each kit comes complete with everything you need for installation, including assembly grease packet for uniform load distribution and accurate torque readings.
