Main Stud Kit 2008-2010 Ford 6.4L Powerstroke XDP Xtreme Diesel Performance

Swap out the factory main bolts on your 2008-2010 Ford 6.4L Powerstroke with the XDP Main Stud Kit XD3005MS. Featuring 8740 Chrome Moly construction with an added proprietary element for additional strength to ensure these studs will not stretch like the factory bolts. These heavy-duty studs are rated at 220,000 plus psi tensile strength and 210,000 plus psi yield strength to provide better clamping force under higher combustion pressures. The threads are rolled after heat-treating to provide optimum fatigue strength. In addition to the upgraded strength, replacing the OEM main 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 are a must-have for high-performance applications and are reusable, unlike the OEM Torque-To-Yield (TTY) bolts which must be
