High-Strength Wheel Studs for Racing Applications

When you are pushing your vehicle to the limit on the track or the street, your wheel fasteners are a critical point of failure that you cannot ignore. This Auto Racing Products (ARP) wheel stud kit is designed to provide the ultimate in safety and reliability. Manufactured from premium-grade chromoly steel and finished with a durable cadmium plating, these studs are built to withstand the extreme stress of high-performance driving and frequent wheel changes.

Key Specifications

  • Thread Size: M12 x 1.5
  • Stud Length: 2.500 inches
  • Knurl Diameter: 0.509 inches
  • Material: High-strength Chromoly
  • Finish: Corrosion-resistant Cadmium
  • Quantity: Set of 5 studs

These studs are an ideal upgrade for late-model GM F-Body vehicles and other platforms requiring these specific dimensions. The 2.500-inch length provides the necessary clearance for thick-hub racing wheels or the use of wheel spacers, ensuring you always have full thread engagement for your lug nuts. Unlike standard OEM studs, these ARP units are heat-treated to provide significantly higher tensile strength, preventing the snapping or stretching that can occur under heavy cornering or launch loads. Don't settle for inferior hardware when your safety is on the line. Ensure your wheels stay securely attached with this professional-grade kit from GGCRACING.
