About this item

• ULTRA STRENGTH - XOTIC 7200 material properties allow for far greater tensile strength compared to 8740 chromoly steel head studs. Rated at 220,000 psi tensile strength, these main studs far exceed clamping forces provided by standard head bolts.
• EASY INSTALLATION - Broached stud ends install & make cylinder head removal easier. Installation manual is included with drawn diagrams to ease the installation process. Head studs are designed to retain cylinder seal even with today's extreme high pressure turbo systems. These studs far exceed clamping forces provided by standard Chevy head bolts.
• KIT INCLUDES - 10x M14 Main Studs, 10x Nuts, 10x Washers, 10x M12 Torx Bolts, 1x Allen Wrench, 1x Fastener Assembly Lubricant, and 2x Sockets.
• ENHANCED MAIN CAP ALIGNMENT - Utilizing main studs is essential for optimal load handling and minimizing wear on the block threads. They aid in keeping the main caps properly aligned, and the risk of main caps shifting is reduced since the studs remain fixed while the caps are secured. These main studs significantly surpass the clamping strength offered by standard head bolts.
• MAIN STUDS - These are main studs, not head studs. Main and head studs serve different purposes—selecting the right one is crucial. For head studs, search more in our catalog.
• DIRECT FIT REPLACEMENT - Fits Ford PowerStroke 6.6L Chevrolet Duramax 2001-2005 LB7 LLY engines. Please see vehicle compatibilities tab above to ensure accurate fitment.
