Product Details

The ARP 184-4003 is a professional-grade cylinder head stud kit engineered for high-performance and racing applications. These studs deliver superior clamping force and reliability compared to standard head bolts, making them the preferred choice of professional engine builders worldwide.

Premium 8740 Chrome Moly Construction:

Manufactured from premium 8740 chrome moly alloy steel, each stud is heat-treated to 200,000 psi tensile strength. ARP's vertical rack heat-treating process ensures complete and uniform heat penetration throughout every stud, resulting in consistent material properties and exceptional strength that surpasses aircraft-quality fasteners.

Precision Manufacturing Process:

  • Centerless ground after heat-treat for near-perfect concentricity and straightness
  • Thread rolled after heat-treatment for 10x better fatigue strength than pre-threaded studs
  • Undercut design on shorter studs equalizes stretch for consistent clamping force
  • Hex head design for reliable installation and torquing
  • Includes hardened parallel-ground washers for even load distribution

Why Studs Over Bolts:

Head studs provide significant advantages for performance applications. Unlike bolts that experience both torsional and tensile stress during installation, studs stretch only along the vertical axis when torqued. This results in more accurate torque readings and consistent clamping force. The precision tolerances allow cylinder heads and gaskets to align perfectly during assembly, which is critical for racing engines that require frequent servicing.

Installation Notes:

Install studs finger-tight in a relaxed state—never force them in with a jammed nut. The undercut design compensates for head gasket compression, helping prevent gasket failures. Always re-torque after initial engine run-in as gaskets will compress during the break-in period.

Each stud is stamped with the ARP logo as your assurance of quality and carries ARP's ZERO defect, ZERO failure quality standard.

It was great!

Very easy to use. Product delivered faster than what I thought

I appreciate the fast delivery time!

had to send back wrong part

Cheaper than most. But processing and shipping took longer than jegs or summit

Prices were good and the order shipped promptly. The email notice of shipment was a little late. It came after the order had arrived.

Product delivered as expected within 4 days. Lowest price on the web. No complaints.

Nobody else had part in stock. Instant shipping and a good price. Will do business again!
