About ARP

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.

Professional Grade Engine Fasteners

When building a high-performance engine, the integrity of your cylinder head seal is paramount. The ARP M10 x 6.9in Head Stud is engineered to provide superior clamping force compared to standard OEM bolts. Manufactured from premium 8740 chromoly steel, these studs are heat-treated to ensure they withstand the extreme thermal cycling and cylinder pressures found in forced induction and high-compression racing applications.

Key Technical Specifications

  • Thread Size: M10
  • Stud Length: 6.9 inches
  • Material: 8740 Chromoly Steel
  • Finish: Black Oxide for corrosion resistance
  • Application: Universal high-performance engine builds

Using ARP hardware prevents head gasket failure by ensuring even torque distribution across the cylinder head surface. Unlike traditional bolts that can twist and bind during installation, these studs allow for more accurate torque readings and consistent preload. This is a critical upgrade for any enthusiast looking to push their engine beyond stock limits. Whether you are performing a full engine overhaul or replacing a single damaged fastener, choosing genuine ARP components ensures your build remains reliable under the most demanding track conditions. Trust your engine build to the industry leader in fastener technology. Find all your essential engine hardware and performance components at GGCRACING.
