PPE 318034800 Head Stud Kit

When maximum strength and precision matter, the PPE 318034800 Head Stud Kit is engineered to meet the demands of high-performance diesel engine builds. Designed for builders who expect more than factory hardware can provide, this stud kit delivers superior clamping force, durability, and long-term reliability in both stock and high-output applications.

Each head stud is centerless ground for exceptional dimensional accuracy and thread rolled to Mil-S-8879 specifications. This manufacturing process improves thread strength while reducing stress concentrations, resulting in a fastener that outperforms OEM hardware. Independent testing has verified a tensile strength exceeding 231,900 PSI, making these studs well-suited for engines subjected to increased cylinder pressure.

The kit includes all necessary installation components, such as hardened parallel washers, nuts, and a specially formulated assembly lubricant to promote even load distribution and accurate torque readings. For best results, properly cleaned threads are critical during installation. XDP thread cleaning chasers are recommended to help ensure accurate torque values and long-term engine reliability.

Features:

• Manufactured from High-Strength Chromoly Alloy Steel
• Tensile Strength Rated at Over 230,000 PSI
• Suitable for High-Performance and Stock Engine Applications
• Black Oxide Finish for Corrosion Resistance
• Precision Thread Rolled for Reduced Stress and Increased Durability
