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.

Extended Reach, Unyielding Strength: ARP 7/16" Neckdown Stud - 4.500" Long, 3/8" Head

For applications demanding both an extended reach and a compact head profile, the Auto Racing Products 7/16-inch Neckdown Stud, precisely 4.500 inches long with a 3/8-inch head, is the ultimate fastening solution. Forged from premium chromoly steel, this stud delivers exceptional tensile strength and resilience, crucial for securing components in deep or hard-to-reach locations within high-performance vehicles. The protective black oxide finish not only provides a professional appearance but also ensures robust resistance against corrosion and wear, guaranteeing long-lasting integrity.

Versatile Design for Complex Installations

The innovative neckdown design allows for a reduced 3/8-inch head diameter, enabling installation in areas with limited overhead clearance, while the 7/16-inch shank maintains superior structural integrity. This stud also features a broached end, simplifying the installation and removal process by allowing for secure tool engagement and precise torque application. With both 3/8-24 and 7/16-14 thread pitches, this versatile component offers broad compatibility, making it ideal for custom engine mounts, chassis bracing, or specialized accessory installations requiring a longer, yet compact, fastener.

Key Features & Benefits:

  • Neckdown Configuration: Features a smaller 3/8-inch head for enhanced clearance in tight spots.
  • High-Strength Chromoly Steel: Provides maximum durability and resistance to stretching under extreme loads.
  • Corrosion-Resistant Black Oxide: Ensures long-term protection against rust and environmental factors.
  • Broached End: Facilitates easy and secure installation/removal using an internal hex tool.
  • Dual Thread Compatibility (3/8-24 & 7/16-14): Adapts to a wide array of component and nut specifications.
  • 4.500-inch Extended Length: Perfect for deep mounting applications requiring significant thread engagement.

The Foundation of a Reliable Build

Auto Racing Products (ARP) neckdown studs are meticulously engineered to provide the highest level of performance and reliability for demanding automotive and racing applications. Their unique combination of extended length, compact head, and superior material strength makes them an indispensable choice for complex projects where standard fasteners simply won't suffice. Trust in ARP's legacy of quality to secure your vital components with confidence. Find your essential racing hardware at GGCRACING.
