Maximum Cylinder Head Clamping Force

Prevent head gasket failure and maintain optimal combustion chamber sealing with the Auto Racing Products Cylinder Head Stud Kit. Designed for the 2.0L DOHC Vauxhall and Opel engine platforms, this kit is an essential upgrade for any high-compression or forced-induction build.

Why Choose ARP Studs?

  • Superior Clamping Force: Prevents head lift under high boost or high RPM
  • 12-Point Nuts: Allows for precise torque and easy socket clearance
  • Material: High-strength heat-treated chromoly steel
  • Finish: Durable black oxide for corrosion resistance
  • Complete Kit: Includes everything needed for a professional installation

Unlike standard head bolts, these studs allow for more accurate torque readings because the studs do not undergo torsional stress during installation. This ensures that the clamping force is applied evenly across the cylinder head, promoting a perfect seal every time. The 12-point nuts are engineered to withstand extreme heat and pressure, making them the preferred choice for tuners and engine builders worldwide. By upgrading to these studs, you eliminate the risk of stretched bolts and blown gaskets, providing the peace of mind required for high-performance driving. Experience the reliability of professional-grade engine fasteners available through GGCRACING.
