Upgrade the factory head bolts in your 2003-2007 Ford 6.0L Powerstroke with the XDP X220 Series Head Stud Kit XD3001HS. With only four head bolts per cylinder, and just 10 per bank, the 6.0 engine is infamous for cylinder head gasket issues. When adding horsepower and torque to your Powerstroke, or even in stock applications as preventive maintenance, upgrading the factory head bolts is a necessity to avoid a lifted cylinder head, or a failed head gasket, due to factory bolt stretch. Each stud is constructed utilizing 8740 Chromoly Steel with an added proprietary element. The threads are then rolled after heat-treating to provide optimum fatigue strength. These heavy-duty 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.

In addition to the upgraded strength, replacing the OEM head bolts with studs also allows you to obtain a more accurate 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 head stud the force gets applied to the vertical axis, resulting in a more even clamping force. Another benefit of studs is they can provide for easier engine assembly and proper alignment of the cylinder heads every time. These studs 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 head studs are manufactured in an ISO/TS 16949 quality control facility. For a hassle-free installation, each set includes installation instructions. Assembly lubricant sold separately.
