Swap out the factory main bolts on your 2008-2010 Ford 6.4L Powerstroke with the XDP X220 Main Stud Kit XD3005MS. Featuring 8740 Chromoly 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+ psi tensile strength and 210,000+ 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 replaced after each use.
Furthermore, they also allow for easier engine assembly and proper alignment of the main bearing caps every time. Installation instructions are included for a hassle-free installation. Assembly lubricant sold separately.
Features:
- Includes Washers & 12 Point Nuts
- Yield Strength: 210,000-230,000 PSI
- Tensile Strength: 220,000-236,000 PSI
- Threads Rolled After Heat Treatment
- Reusable Studs, Unlike TTY OEM Bolts
- 10mm Studs Test Out At Max Load Of Over 120KN
- 8740 Chromoly Construction With Added Proprietary Element
XDP Thread Cleaning Chasers (Sold Separately):
The XD40126TC is 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.
