ARP Cylinder Head Stud Kit Chrome Moly Undercut

The ARP chrome moly undercut cylinder head stud kit is a high-strength fastener set for engine builders who want dependable clamping force and consistent head gasket sealing. Often called head studs or cylinder head bolts, these studs replace factory head bolts. They are a common upgrade for performance, racing, and heavy-duty engine builds.

Key Features:

• Chrome moly construction: Made from chromium-molybdenum alloy steel for strength and fatigue resistance.
• Undercut shank design: The reduced-diameter shank section allows more even stretch and load distribution along the stud. This helps maintain accurate clamp load.
• Stud-style design: Studs allow more accurate torque readings than bolts. They also reduce twisting stress on the block threads during installation.
• Rolled threads: ARP rolls its threads after heat treatment, which improves strength and fatigue life.
• Precision manufacturing: ARP fasteners are made in the USA to tight quality standards.

Installation should follow the ARP-supplied instructions and lubricant guidelines for the correct torque values. Each kit in this product line is built for a specific application. ARP is a trusted name in high-performance and racing fasteners.
