About this item

• 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.
• IMPROVED CAP ALIGNMENT - Main studs are required for maximum loading & reduced wear and tear on the block threads. They assist with main cap alignment, and there is less of a change of main cap walking because the studs remain stationary during cap clamping. These main studs far exceed clamping forces provided by standard head bolts.
• Simplified installation process - Stud ends broached for easier cylinder head removal. Includes manual with diagrams for guidance. Designed for high pressure turbo systems, ensuring seal retention. Provides superior clamping forces compared to 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.
• 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.
• 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.
