About Auto Racing Products

ARP (Automotive Racing Products) makes the strongest fasteners in motorsport — head studs, main studs, rod bolts, and flexplate bolts used by every Formula 1, NHRA, NASCAR, and championship motorsport program. Aerospace-grade alloys, exact-fit machining.

Heavy-Duty 5.150-Inch Broached Studs

When standard fasteners fall short, the Auto Racing Products 5.150-inch broached stud provides the extra length and strength required for complex custom engine builds. Designed for high-performance applications, these 3/8-inch studs are crafted from premium chromoly steel to ensure they can handle the high-stress environments of professional racing. The broached head design ensures that even at this length, you can maintain precise control during installation.

Advanced Fastener Technology

  • Extended Length: 5.150 inches for custom clearance needs.
  • Material: Heat-treated chromoly for maximum durability.
  • Installation: Broached head for secure, slip-free tightening.
  • Threads: Dual 3/8-16 and 3/8-24 thread pitch.
  • Finish: Durable black oxide coating.

The 5.150-inch length is perfect for unique mounting scenarios where reach is a challenge. By using these studs, you ensure that your components are anchored securely, preventing vibration-induced loosening and potential engine damage. The chromoly steel provides a high modulus of elasticity, meaning these studs will hold their torque settings longer than standard steel alternatives. The black oxide finish provides a professional aesthetic while protecting the metal from oxidation in harsh racing environments. Whether you are building a custom turbo setup, a specialized intake, or a high-output valvetrain, these studs offer the reliability and precision you need to cross the finish line first. Trust in the quality of Auto Racing Products to keep your engine together. Discover the full range of high-performance hardware available at GGCRACING.
