Construction & Design

The ARP Hex Bolt Kits are constructed from 8740 chromoly steel, a material renowned for its excellent strength-to-weight ratio and toughness. The bolts undergo a specialized heat treatment process to maximize tensile strength and fatigue resistance, ensuring they can withstand high-stress conditions without failure. The black oxide finish not only enhances corrosion resistance but also provides a professional, finished look suitable for performance applications.

The flanged hex head design allows for easy installation with standard wrenches or sockets, providing a secure grip and reducing the risk of stripping or rounding off the head. The precise threading and dimensions ensure compatibility with a variety of components, making these bolts a versatile choice for many projects.

Performance & Reliability

Designed for high-performance and safety-critical applications, these ARP bolts offer a substantial upgrade over typical factory hardware. Their high tensile strength ensures they can handle increased loads and torque, supporting the integrity of your assembly under demanding conditions. Whether used in engine components, suspension systems, or trailer connections, these bolts help maintain secure fastening and reduce the risk of failure.

While not explicitly rated for racing or extreme off-road use, their robust construction makes them suitable for spirited driving, towing, and heavy-duty applications where strength and reliability are paramount.

Installation & Fitment

Installing the ARP Hex Bolt Kits is straightforward and requires no special tools beyond standard wrenches or sockets. The bolts are designed to thread directly into compatible threaded holes, with a 12mm diameter and 1.75mm pitch. Ensure that the mating threads are clean and free of debris before installation. Proper torque specifications should be followed to achieve optimal clamping force and prevent over-tightening.

No cutting, drilling, or additional modifications are necessary for most standard applications, making these bolts a convenient upgrade or replacement option.
