ARP Pro Series Cylinder Head Bolt Kit

The ARP Pro Series cylinder head bolt kit (also sold as a head bolt set or head fastener kit) is built to clamp cylinder heads securely in street performance, racing, and heavy-duty engine builds. Pro Series fasteners are made for builders who want better clamping strength and durability than standard factory head bolts offer.

Key Features:

• Made in the USA by ARP, a trusted name in high-performance fasteners
• Built from high-strength alloy steel for strong, consistent clamp load
• Rolled threads, a process that improves fatigue strength and thread accuracy
• Precision-machined heads and shanks for proper seating and even torque
• Corrosion-resistant finish to protect the hardware during storage and use
• Designed to help maintain head gasket sealing under higher cylinder pressures

Pro Series head bolt kits suit engine rebuilds, performance upgrades, and race applications. Use the supplied assembly lube and follow the manufacturer's torque procedure for best results. Choose the specific kit from the available variants for your engine.
