ARP Engine Cylinder Head Bolt Set

ARP cylinder head bolt sets (also sold as head bolt kits or head stud and bolt hardware) are made to clamp the cylinder head to the engine block. They hold the head gasket seal under high cylinder pressure, heat cycling, and the stress of performance driving or racing.

Key Features:

• Made in the USA by ARP, a long-time supplier of fasteners for performance and racing engines
• Built from high-strength alloy steel, with premium material options across the product line
• Rolled threads for better fatigue strength and a more consistent fit
• Designed for even clamping load, which helps the head gasket seal reliably
• Supplied with the hardware required for installation as documented for each part number
• Suited to street performance, towing, forced-induction, and competition builds

ARP applies tight quality control and testing to its fasteners. Each part number in this line is built for a specific engine application, so you can choose the head bolt set that suits your build. Use the recommended ARP assembly lubricant and torque procedure for best results.
