• Heat-treated to enhance tensile strength and resistance to thermal cycling, which is critical for high-performance engine builds.
• Forged construction with a larger-than-stock shank diameter provides increased shear strength and improved register, reducing the risk of bolt failure.
• Exclusive flat, 12-point head design allows for easier installation and removal in tight engine bays, providing better access compared to traditional hex heads.
• Black oxide finish not only adds corrosion resistance but also gives a sleek, professional appearance.
• Precisely machined threads ensure proper engagement and torque accuracy, vital for maintaining proper clamping force.
• Compatible with multiple Ford engine models, making it a versatile upgrade for various applications.
• Includes washers for optimal load distribution and secure fastening.
• Ideal for high-performance builds, racing, or any scenario where maximum strength fasteners are required.

Construction & Design

The ARP Crank Flange Adapter Bolt Kit features a meticulously engineered design utilizing aerospace-grade chromoly steel, renowned for its exceptional strength-to-weight ratio. The forging process creates a dense, uniform microstructure that enhances fatigue resistance and overall durability. The heat treatment process further refines the material properties, ensuring the bolts can withstand extreme engine conditions.

The flat, 12-point head design not only facilitates easier installation in confined spaces but also provides increased contact surface for torque application, reducing the risk of stripping or rounding off the head. The larger shank diameter improves the bolt's shear strength, supporting higher torque loads and reducing the likelihood of bolt stretch or failure during high-RPM or high-horsepower scenarios.

Finished with a black oxide coating, these bolts resist corrosion and maintain their appearance over time, even in demanding environments. The precision thread rolling process ensures smooth engagement and consistent torque values, critical for maintaining proper clamping force on the crank flange.

Performance & Reliability

While specific performance numbers are not provided, the ARP High Performance Series bolts are trusted by engine builders worldwide for their proven strength and reliability. They help support increased horsepower and torque by maintaining secure fastening under high-stress conditions. Their superior material properties and construction make them a dependable choice for both street and race applications, ensuring your engine's integrity during demanding driving scenarios.

Installation & Fitment

These bolts are designed as direct replacements for OEM hardware, offering a bolt-on installation with no modifications required. Proper torque specifications should be followed as per ARP's guidelines to ensure optimal clamping force and safety. The kit is compatible with a range of Ford engines, but it is recommended to verify fitment for your specific model and year before installation.

No cutting, drilling, or special tuning is necessary when installing these bolts, making them a straightforward upgrade for your engine assembly.
