Product Details

The ARP 234-4506 cylinder head stud kit delivers professional-grade fastening performance for high-performance and racing engines. Manufactured from premium 8740 chrome moly steel and rated at 200,000 psi tensile strength, these studs provide superior clamping force and reliability compared to standard head bolts.

Key Features:

  • Premium 8740 chrome moly steel construction rated at 200,000 psi tensile strength
  • Precision heat-treated using vertical rack process for complete and uniform heat penetration
  • Centerless ground after heat-treat for exceptional concentricity and straightness
  • Thread rolled after heat-treatment for 10x better fatigue strength versus pre-heat-treat threading
  • Undercut shorter studs equalize stretch for more consistent clamping force
  • Hex head design for reliable wrenching
  • Includes hardened parallel-ground washers for even load distribution
  • Facilitates easier engine assembly with perfect head and gasket alignment

Why Choose Studs Over Bolts:

Head studs provide significant advantages for performance applications. Unlike bolts that experience both torsional and tensile loads during installation, studs stretch only along the vertical axis when the nut is torqued. This results in more accurate and consistent torque readings and superior clamping force. The undercut design on shorter studs helps compensate for head gasket compression, reducing the risk of gasket failure.

Installation Notes:

Install studs finger-tight in a relaxed mode—never force them in using a jammed nut. After initial torquing and engine run-in, always re-torque the nuts to compensate for head gasket compression. The precision manufacturing ensures cylinder heads and gaskets glide into perfect alignment during assembly.

Trusted by professional engine builders across all forms of motorsports, ARP fasteners meet the company's zero-defect, zero-failure quality standard. Each stud is stamped with the ARP logo as assurance of genuine quality and performance.

Lowest price that i could find,fast shipping!!!!!<br>

It took exactly a week for the part to be shipped because the part came directly from the supplier. But the price was the lowest around.

I just received my order 7260 very quickly and it was as I had ordered............very easy to order and would do business with them again and I also will recommend them to others.

Good service, great products and quick shipping. I received a good shipping discount using Google payment. Only problem was the item was shipped to my billing address instead of my shipping address.

Better prices and even better service. Will do business with again.

Perfect item, fast shipment, great communication, and the best price.

They had exactly what I needed and the cheapest price i found anywhere.
