Construction & Design

The ARP 12pt Hardware Kit is constructed from 8740 chromoly steel, a material renowned for its high strength-to-weight ratio and durability. The fasteners undergo a proprietary heat treatment process that significantly enhances their tensile strength, ensuring they can withstand the stresses of high-performance and heavy-duty applications. The black oxide finish not only provides a sleek appearance but also offers excellent corrosion resistance, extending the lifespan of the hardware in harsh environments.

The 12-point head design allows for better grip and torque application, reducing the risk of stripping or cam-out during installation. This design is especially useful in tight spaces where a standard hex head might be difficult to access. The precise threading ensures a secure fit and consistent torque, critical for maintaining the integrity of assembled components.

Performance & Reliability

Designed for demanding applications, the ARP 12pt Hardware Kit delivers exceptional strength and reliability. Its high tensile rating ensures that fasteners will maintain their integrity under high loads, making it suitable for securing engine parts, suspension components, or trailer hardware. The quality materials and manufacturing processes used by ARP guarantee that these bolts will perform consistently over time, even in challenging conditions.

Installation & Fitment

The ARP 12pt Hardware Kit is a bolt-on solution that requires no special tools beyond standard wrenches or sockets. Its precise threading and high-quality construction ensure a straightforward installation process. No cutting, drilling, or special tuning is necessary, making it an ideal upgrade or replacement for OEM hardware or custom builds.
