Replace the weak OEM head bolts on your 2011-2021 6.7L Powerstroke with the XDP X220 Series Head Stud Kit XD3018HS. Upgrading the factory head bolts is a must when you start adding horsepower and torque to your Super Duty.

The stock head bolts can struggle to handle the additional pressure in high-performance applications which leads to the cylinder head lifting. Upgrading to head studs helps to keep the cylinder heads locked down and avoid head gasket failures.

Constructed using an 8740 Chrome Moly with an added proprietary element ensures these studs will not stretch like the stock bolts. The threads are rolled after heat-treating to deliver optimum fatigue strength.

These studs are rated at 210,000 plus psi yield strength and 220,000 plus psi tensile strength to ensure a strong hold under higher combustion pressures.

In addition to the upgraded strength, replacing the head bolts with studs also allows you to obtain a more precise torque reading. A bolt gets twisted as it is tightened, so it's reacting to two different forces at the same time.

With a head stud the force gets applied to the vertical axis, resulting in a more even clamping force. Another benefit of studs is they can help offer easier engine assembly and proper alignment of the cylinder heads every time.

These are a must-have for high-performance applications and are reusable, unlike the OEM Torque-To-Yield (TTY) bolts which must be replaced after each use. These studs are manufactured in an ISO/TS 16949 quality control facility. Included with the studs are 12-point nuts and washers.

• Includes Washers and 12-Point Nuts
• Yield Strength 210K psi - 230K psi
• Tensile Strength 220K psi - 236K psi
• Will Not Stretch Like The Factory Studs

• High-Strength 8740 Chrome Moly Construction
• 10mm Studs Test Out At A Max Load: Over 120KN
• Manufactured In An ISO/TS 16949 Quality Control Factory
• Studs Are Reusable, Unlike Torque-To-Yield (TTY) Bolts Which Much Be Replaced After Each Use

XDP Thread Cleaning Chasers (Sold Separately):
Both the XD40125TC, and XD40128TC are a great add-on that will be critical during installation. Thread Cleaning Chasers are an excellent tool to have on-hand to ensure you have properly cleaned the threads in your engine block before the installation of any fasteners. Clean threads provide accurate torque readings and will help give you peace of mind during your engine build or head gasket repair.
