Key Features

ARP's Pro Series cylinder head bolts are manufactured from high-quality materials and feature advanced processing techniques to deliver exceptional strength and durability. The bolts are cold-forged, a process that aligns the metal's molecular structure for maximum integrity, resulting in a tensile strength rated at an impressive 190,000 psi. This ensures that your engine maintains proper head gasket sealing even under extreme conditions.

• Cold-forged construction for enhanced molecular integrity and strength
• Heat-treated prior to thread rolling and machining for consistent performance
• Rated at 190,000 psi tensile strength for maximum load capacity
• Complete with hardened parallel washers for even load distribution
• Available with hex or 12-point heads to suit different applications and preferences
• Designed specifically for SB Ford Windsor heads, but compatible with multiple Ford engines
• Precision-machined threads ensure accurate torque readings and secure fitment
• Corrosion-resistant finish for durability in various operating environments
• Ideal for high-performance builds, engine rebuilds, and racing applications

Construction & Design

The ARP Head Bolt Kit features a meticulously engineered design that emphasizes strength, reliability, and ease of installation. The bolts are made from ARP's proprietary 8740 chrome-moly steel, which is known for its exceptional toughness and fatigue resistance. The cold-forging process aligns the grain structure of the steel, significantly increasing tensile strength and ensuring the bolts can handle the stresses of high-performance operation.

Each bolt is heat-treated to a precise specification before thread rolling and machining, which guarantees consistent dimensions and load distribution. The inclusion of hardened parallel washers ensures that load is evenly spread across the cylinder head surface, reducing the risk of warping or damage. The choice between hex and 12-point head designs allows for versatile installation options, accommodating different socket types and accessibility constraints.

Performance & Reliability

Designed for demanding applications, these ARP head bolts provide the clamping force necessary to keep your cylinder heads sealed under high boost, elevated RPMs, or aggressive driving conditions. Their high tensile strength and superior construction help prevent head gasket failure, leaks, and head warping, contributing to improved engine performance and durability. Whether you're building a race engine or restoring a classic Ford, these bolts deliver the strength and reliability you need.

Installation & Fitment

Installing the ARP Head Bolt Kit is straightforward for experienced mechanics and enthusiasts familiar with engine assembly. The bolts are designed to replace factory head bolts directly, with no modifications required. Proper torque specifications provided by ARP should be followed to ensure optimal clamping force and sealing. No special tools or procedures are necessary beyond standard torque wrench use. Always clean threads and apply assembly lubricant as recommended for best results.
