XDP XD3013HS X220 SERIES HEAD STUD KIT FOR 94-03 FORD SUPERDUTY WITH 7.3L POWERSTROKE ENGINE

The XDP X220 Series Head Stud Kit XD3013HS provides your 1994-2003 Ford 7.3L Powerstroke with the increased clamping power you need. Upgrading the factory head bolts is a must when adding horsepower and torque to your Super Duty.

The OEM bolts typically can't handle the additional pressure from high-performance applications which can lead to the cylinder heads lifting. Upgrading to studs helps keep your cylinder heads locked down and avoid head gasket failures. The XDP head studs are constructed from high-quality 8740 Chromoly Steel that also includes a proprietary element added for superior strength and durability.

The threads are rolled after heat-treating to deliver maximum fatigue strength. These head studs are rated at 225,000+ psi tensile strength and 205,000+ psi yield strength to ensure the cylinder heads on your engine stay locked in place under higher combustion pressures. Assembly lubricant sold separately.

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

With a stud the force gets applied to the vertical axis, resulting in a more even clamping force. These studs are reusable, unlike OEM Torque-To-Yield (TTY) studs which must be replaced after each use. Another benefit of studs is proper alignment of the cylinder heads every time and provides for easier engine assembly. Included with the stud kit are washers and 12-point nuts.

Features:

• Includes Washers & 12 Point Nuts
• Yield Strength 205K psi - 215K psi
• Tensile Strength 225K psi - 233K psi
• Will Not Stretch Like The Factory Studs
• Thread Has Been Rolled After Heat Treatment
• High-Strength 8740 Chromoly Steel Construction
• 10mm Studs Test Out At A Max Load: Over 120KN
• Studs Are Reusable, Unlike Torque-To-Yield (TTY) Bolts Which Much Be Replaced After Each Use

Tech Tips:
XDP Thread Cleaning Chaser (Sold Separately, See Related Items):
Purchase the XDP Thread Cleaning Chaser XD40125TC as an add-on to this kit. Using a Thread Cleaning Chaser ensures that you are able to properly clean the threads in your engine block before you begin installation and torquing of your new XDP head studs. Clean threads are critical to provide you with accurate torque readings during your engine build or head gasket repair.

XDP X-TRA Slick Engine & Fastener Assembly Lubricant (Sold Separately):
The use of XD541 is highly recommended during engine assembly. Apply XDP X-TRA Slick Lubricant to head studs, head bolts, main studs, main bolts, connecting rod bolts, and any other fasteners used during engine assembly. Using a proper assembly lubricant during fastener installation reduces friction and torque pre-load scatter in the torquing sequence, while also helping to prevent thread galling and seizing.

The XDP XD3013HS X220 Series Head Stud Kit is an essential upgrade for owners of 1994-2003 Ford Super Duty trucks equipped with the 7.3L Powerstroke engine. Designed to provide superior clamping power, this head stud kit is crucial for those looking to increase horsepower and torque without compromising engine integrity. Factory head bolts often fall short under the higher pressures typical of high-performance applications, leading to issues such as cylinder head lifting and gasket failures.

Crafted from high-quality 8740 Chromoly Steel, the XDP head studs undergo a specialized heat treatment process, enhancing their strength and durability. With a tensile strength exceeding 225,000 psi and yield strength of 205,000 psi, these studs ensure that your cylinder heads remain securely fastened even in demanding conditions. Unlike traditional bolts, these studs offer improved precision in torque application. This design minimizes twisting and allows for a more uniform clamping force, critical for achieving optimal performance.

The reusability of the XDP studs further distinguishes them from standard Torque-To-Yield (TTY) bolts, which require replacement with every installation. The included washers and 12-point nuts contribute to a complete package, promoting accurate and reliable assembly. Furthermore, proper alignment of cylinder heads is effortlessly achieved each time, facilitating easier engine builds and repairs.

For those looking to enhance installation accuracy, the XDP Thread Cleaning Chaser and X-TRA Slick Engine Lubricant (both sold separately) are recommended additions. These tools ensure clean thread conditions and reduce friction during assembly, delivering effective torque and preventing any potential seizing. Invest in the XDP XD3013HS Head Stud Kit for unmatched performance and peace of mind in your engine's reliability.
