Main Cap Stud Kit BBF FE w/Bolts for #5 Cap

The Main Cap Stud Kit BBF FE w/Bolts for #5 Cap from ARP is purpose-built for serious engine builders and performance shops working with classic Ford FE-series big-block platforms. This fastener kit delivers the precision and reliability demanded in high-stress, high-horsepower builds where factory hardware simply won't cut it. Whether you're restoring a vintage muscle car, building a street performer, or preparing competition power, upgrading to quality main cap studs is non-negotiable for long-term durability and consistent performance.

Constructed from chromoly steel with black oxide finish, this main cap stud kit resists corrosion while providing superior tensile strength compared to OEM fasteners. The twelve-point nut design increases surface contact area and grip, reducing the risk of slippage during installation and under load cycling. ARP's two-bolt main configuration is engineered specifically for Ford FE-series engines, ensuring proper clamping force distribution across the block saddle and cap interface. The black oxide coating protects against rust in both new builds and restorations exposed to ambient moisture, while maintaining a professional appearance in engine bays.

Engine builders, restoration shops, and performance enthusiasts working on Ford 427, 455, or other FE-series displacement engines will recognize this kit as essential infrastructure for builds exceeding factory power targets. Installation requires standard socket and torque wrench methodology—critical fasteners demand proper sequencing and specification torque values to prevent block cracking or bearing misalignment. Compatible with #5 cap applications, this kit comes complete with all necessary bolts for a direct swap, eliminating sourcing delays and ensuring matched fastener quality throughout the main bearing assembly.
