Professional-Grade Fasteners for Aftermarket BBC

For high-performance Big Block Chevy engines utilizing aftermarket cylinder heads, standard fasteners often fall short. This Auto Racing Products (ARP) head stud kit is designed to handle the increased stress of modified engines. The 12-point nut design provides superior clearance and allows for higher torque values, ensuring your cylinder heads stay firmly in place under extreme cylinder pressures.

Why Choose This 12-Point Kit?

  • Application: Big Block Chevy with Aftermarket Heads
  • Fastener Style: 12-Point Nuts
  • Material: Premium 8740 Chromoly Steel
  • Design: Undercut Studs for Uniform Stretch
  • Finish: Black Oxide

The use of undercut studs is a key advantage in this kit, as it allows the stud to stretch more uniformly, which helps maintain consistent clamping force even as the engine heats up and expands. Manufactured from high-tensile chromoly steel and finished with a durable black oxide coating, these studs are built to resist corrosion and fatigue. The 12-point design is preferred by engine builders for its ability to provide more accurate torque readings and its compact profile, which is perfect for engines with limited space around the cylinder head. By upgrading to this kit, you are choosing the same level of quality used by top-tier racing teams worldwide. Ensure your engine's integrity and performance with the best hardware available on the market. Find all your essential engine build components at GGCRACING.
