ARP High Performance Cylinder Head Stud Kit Chrome Moly Steel

The ARP High Performance Cylinder Head Stud Kit is a chrome moly steel cylinder head stud set. It replaces factory head bolts or studs and gives the cylinder head more clamping force. ARP (Automotive Racing Products) builds its fasteners for street performance, racing, and high-horsepower engine builds.

Key Features:

• Chrome moly steel construction for high tensile strength and fatigue resistance
• Stud design applies clamping load more evenly than standard head bolts. It also reduces twisting force on the threads during installation.
• Rolled threads are a standard ARP manufacturing practice. They improve strength and fatigue life.
• Better head gasket sealing under high cylinder pressure, including in boosted, nitrous, and high-compression applications
• Easier repeat service. Studs stay in the block when the heads are removed, so the block threads see less wear.
• Kit format is intended to cover the hardware needed for installation. Contents vary by application, so check the specific part number.

These head studs are a common upgrade for engine rebuilds and performance builds, and they suit builders who want a dependable cylinder head fastening system. Choose the specific part number for your engine in the available variants.
