Key Features

ARP High Performance Series head bolt kits are crafted with the serious engine builder in mind, offering several key features that set them apart:

• Material and Construction: Made from chromoly steel, these bolts are rated at 180,000 psi, making them 15% stronger than traditional Grade 8 fasteners. This high tensile strength ensures they can withstand the stresses of high-performance engines.
• Finish and Corrosion Resistance: The black oxide finish not only provides a sleek, professional appearance but also offers excellent corrosion resistance, extending the service life of the fasteners.
• Design Flexibility: Available with either a reduced wrenching hex head or a 12-point head, these options facilitate easier installation and re-torque procedures, especially when valvetrain removal is undesirable or impractical.
• Included Washers: The kit comes complete with high-quality washers to ensure proper load distribution and secure fastening.
• Compatibility: Designed specifically for multiple AMC engine applications from 2011 to 2025, ensuring a precise fit for your rebuild or upgrade project.
• Ease of Use: The bolt design allows for straightforward installation, with no need for special tools beyond standard socket sets, making it accessible for both professional and DIY mechanics.

Construction & Design

These ARP head bolts feature a one-piece, high-strength chromoly steel construction that guarantees durability and consistent performance under high-stress conditions. The precision-machined threads and specially designed head styles ensure a secure fit and optimal torque application. The black oxide finish not only enhances corrosion resistance but also helps prevent galling during installation. The choice between hex and 12-point head styles provides flexibility to accommodate different engine bay configurations and installer preferences, reducing installation time and effort.

Installation & Fitment

The ARP Head Bolt Kit is designed for a straightforward, bolt-on installation. No special modifications, cutting, or drilling are required.
