ARP Cylinder Head Fasteners High Performance Hex Head Bolts

ARP High Performance Hex Head Cylinder Head Bolts are engine fasteners for clamping the cylinder head to the block. They are made for street performance, racing, and heavy-duty builds. Depending on the application, they are also called head bolts or cylinder head fasteners. They give a secure, consistent clamp load where stock hardware may stretch or lose tension.

Key Features:

• Engineered for high-performance and racing engines that see elevated cylinder pressures, boost, or nitrous
• Made from high-strength alloy materials, selected by ARP for each application
• Rolled threads, a process ARP uses to improve fatigue strength and thread accuracy
• Hex head design allows installation with common sockets and tools
• Built to hold consistent clamp load for better head gasket sealing and fewer leaks
• Made in the USA by ARP, a long-established maker of performance fasteners

Use the specified ARP assembly lubricant and follow the torque procedure in the instructions for your application. This gives accurate clamp load and helps the bolts perform as designed. These bolts are a durable, reliable upgrade for engine builders who want a dependable head-to-block connection.
