Pacific Performance Engineering Head Stud Kit for Ford Power Stroke Diesel

The Pacific Performance Engineering (PPE) Head Stud Kit for Ford Power Stroke diesel engines replaces the factory torque-to-yield cylinder head bolts with high-strength cylinder head studs. It suits owners and engine builders who want a more reliable top end for added boost and horsepower, a turbo upgrade, or heavy-duty use.

Key Features:

• Stud design: The factory bolts load the head from one pressure point. Studs create two points of pressure, which gives a stronger and more even hold on the cylinder head.
• High-strength chromoly construction: The studs are made from chromoly alloy steel with a black oxide finish that protects against corrosion.
• Tested strength: PPE reports an independently tested tensile strength of over 231,900 psi. The studs are recommended for higher-boost applications.
• Precision manufacturing: Each stud is centerless ground and thread rolled to Mil-S-8879 specifications. This improves durability and reduces stress at the threads.
• Installation hardware: Each kit includes studs, nuts and flat washers. It also includes assembly lubricant for even load distribution and accurate torque readings.

Clean the block threads and follow the installation guide for your kit. Use the supplied lubricant and tighten in the specified steps. A trained professional should install the kit. PPE has been building diesel performance parts since 1985, and this kit is designed to keep the cylinder heads sealed under high cylinder pressure.
