Key Features

ARP's High Performance Series head bolt kits are crafted with precision and durability in mind. Key features include:

• Material: Chromoly steel fasteners offer exceptional strength and resistance to stretching under high loads, ensuring long-lasting performance.
• Finish: Black oxide coating provides corrosion resistance and a sleek, professional appearance, helping to protect the fasteners from rust and environmental damage.
• Design: Available with either a reduced wrenching hex head or a 12-point head, allowing for easier installation and re-torqueing without removing valvetrain components.
• Thread Size: 7/16 in.-20, compatible with a wide range of AMC engines requiring this specification.
• Washers Included: Yes, ensuring proper load distribution and sealing during installation.
• Rated Strength: Capable of handling up to 180,000 psi, these fasteners are 15% stronger than standard Grade 8 hardware, providing added security for high-performance builds.

Construction & Design

These head bolts are manufactured from high-quality chromoly steel, known for its excellent strength-to-weight ratio and durability. The black oxide finish not only enhances corrosion resistance but also reduces glare in engine bays. The fasteners are precision-machined to exact specifications, ensuring a perfect fit and consistent clamping force. The choice between a hex head or 12-point head allows technicians to select the most convenient installation method, especially in tight engine compartments. The inclusion of washers helps distribute load evenly, preventing head gasket leaks and ensuring a reliable seal under demanding conditions.

Installation & Fitment

The ARP Head Bolt Kit is designed for straightforward, bolt-on installation. These fasteners are compatible with AMC engines requiring 7/16 in.-20 thread size. No special tools beyond standard socket sets are necessary, and the reduced wrenching hex or 12-point head options facilitate easier access in confined spaces. Typically, no cutting, drilling, or complex modifications are required. Proper torquing sequences and specifications should be followed as per ARP instructions to ensure optimal clamping force and engine integrity.
