XDP XD3004HS X220 SERIES HEAD STUD KIT FOR 08-10 FORD SUPERDUTY WITH 6.4L POWERSTROKE ENGINE

Replace the OEM head bolts in your 2008-2010 Ford 6.4L Powerstroke with the XDP X220 Series Head Stud Kit XD3004HS. Upgrading to these head studs helps avoid the common head gasket failure issues that arise when you start adding more horsepower and torque to your Super Duty.

The 8740 Chromoly Steel construction with an added proprietary element is more durable and will not stretch like the factory bolts. The threads are rolled after heat-treating to provide optimum fatigue strength.

These heavy-duty, reusable head studs are rated at 225,000+ psi tensile strength and 205,000+ yield strength to ensure better clamping force under higher combustion pressures to help prevent a lifted cylinder head or a failed head gasket.

In addition to the increased strength, replacing the factory 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 a must-have for high-horsepower applications and are reusable, unlike the OEM Torque-To-Yield (TTY) bolts which must be replaced after each use.

Another benefit of studs is they provide for easier engine assembly and proper alignment of the cylinder heads every time. For a hassle-free installation, each set includes installation instructions. Assembly lubricant sold separately.

Tech Tips:
XDP Thread Cleaning Chasers (Sold Separately):
The XD40127TC (for head studs) and XD40128TC (for inner row bolts) 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.

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 XD3004HS X220 Series Head Stud Kit is designed specifically for Ford Super Duty trucks equipped with the 6.4L Powerstroke engine from model years 2008 to 2010. This high-performance kit replaces the original equipment manufacturer (OEM) head bolts, offering an essential upgrade for anyone looking to enhance their engine's durability and reliability, particularly when increasing horsepower and torque.

Crafted from 8740 Chromoly Steel, this head stud kit includes a proprietary element that significantly boosts its strength and resistance to stretching—common issues with factory bolts. With a tensile strength exceeding 225,000 psi and yield strength around 205,000 psi, these heavy-duty, reusable head studs provide superior clamping force against higher combustion pressures, effectively preventing head gasket failures and lifted cylinder heads.

An advantage of using head studs over conventional bolts lies in the precise torque readings they deliver. Unlike bolts that twist during tightening, studs ensure that the force is applied directly along the vertical axis, resulting in even clamping. This becomes increasingly vital for those operating high-horsepower setups, as traditional Torque-To-Yield (TTY) bolts require frequent replacement.

The XDP XD3004HS kit not only supports improved strength and stability but also simplifies engine assembly, guaranteeing proper alignment every time. Each kit comes with washers and 12-point nuts, ensuring a complete package for installation. For optimal performance, it’s recommended to use XDP Thread Cleaning Chasers and X-TRA Slick Engine & Fastener Assembly Lubricant—both available separately—to enhance installation efficiency and protect thread integrity.

Upgrade to the XDP XD3004HS X220 Series Head Stud Kit for a robust solution that empowers your Ford Super Duty with unmatched performance and reliability.
