XDP X220 SERIES HEAD STUD KIT XD3013HS

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. These studs are manufactured in an ISO/TS 16949 quality control facility. Included with the stud kit are washers and 12-point nuts.

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 XDPX-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.
