The Mopar Main Stud Kit 5.7L/6.4L Hemi Gen III is an essential upgrade for any serious high-performance or high-mileage Hemi engine build. This kit is designed to replace factory head bolts that may stretch and fail under increased loads, ensuring durability and reliability in demanding conditions.
Constructed from premium alloy steel, these precision-engineered studs provide superior tensile strength compared to OEM fasteners. They are designed to maintain consistent clamp load across all eight cylinders, which is critical for gasket sealing and bearing alignment. The kit includes all necessary fasteners for the five main bearing journals of the Gen III Hemi block.
Ideal for those building a stroker engine, adding forced induction, or reinforcing an aging block, this main stud kit is a non-negotiable component for achieving optimal performance. Proper installation requires head and main cap removal, and using ARP fastener lubricant (sold separately) is recommended to maximize preload consistency and longevity.
