6.6L Chevrolet Duramax 2001-2005 LB7 LLY Main Stud Replacement Kit - Xotic Performance™ MP877

About this item

• 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.
• 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.
• INCLUDED IN THE KIT - 10x Main Studs with M14 thread, 10x Nuts, 10x Washers, 10x Torx Bolts with M12 thread, 1x Allen Wrench, 1x Fastener Assembly Lubricant, and 2x Sockets.
• 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.
• 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.
