Key Features

The ARP Head Bolt Kit boasts several key features that set it apart from standard fasteners:

• Manufactured from 8740 chromoly steel, known for its excellent strength-to-weight ratio and toughness.
• Heat-treated prior to thread rolling and machining, ensuring molecular integrity and maximum durability.
• Rated at an impressive 190,000 psi tensile strength, providing superior clamping force for high-performance applications.
• Available with hex and 12-point head options, allowing for versatile installation and compatibility with various tools.
• Complete with hardened parallel washers, which promote even load distribution across the cylinder head and help achieve accurate torque readings.
• Designed specifically for multiple Chevrolet engine fitments, including popular models and applications requiring high-strength head bolts.

Construction & Design

The ARP Pro Series head bolts are meticulously engineered using advanced manufacturing techniques. The core material, 8740 chromoly steel, is known for its exceptional strength and fatigue resistance. Each bolt undergoes a proprietary heat treatment process that enhances its tensile properties, ensuring it can withstand the extreme pressures and thermal cycles encountered in high-performance engines. The bolts feature a precision-machined thread rolling process that increases the material's strength and surface hardness, further improving their load-bearing capacity.

The inclusion of hardened parallel washers ensures that load is evenly distributed across the cylinder head surface, reducing the risk of warping or gasket failure. The design accommodates both hex and 12-point head styles, providing flexibility for different assembly preferences and tool access. Overall, the construction and design of these bolts prioritize durability, precise fitment, and consistent clamping force, making them a dependable choice for demanding engine builds.

Performance & Reliability

Engine builders and performance enthusiasts rely on ARP's proven manufacturing standards to deliver consistent, high-quality fasteners. The 190,000 psi tensile strength rating indicates these bolts are capable of supporting high horsepower and forced induction setups, helping to maintain proper cylinder head sealing under extreme conditions. Their superior material properties and heat treatment process contribute to reduced stretch and elongation, ensuring reliable torque retention over time.

Installation & Fitment

Installing the ARP Head Bolt Kit is straightforward for experienced mechanics and enthusiasts familiar with engine assembly. These bolts are designed as direct replacements for OEM fasteners, requiring no modifications or special tools beyond standard socket sets. Proper torque sequences and specifications should be followed as per ARP's instructions to achieve optimal clamping force and sealing integrity. No additional machining or preparation is necessary, making this a convenient upgrade for your Chevrolet engine rebuild or performance enhancement project.

• Ensure all threads are clean and free of debris before installation.
• Apply ARP Ultra-Torque Assembly Lubricant to the threads and under the bolt heads for consistent torque readings.
• Follow the recommended torque sequence and specifications provided with the kit for proper installation.
