Construction & Design

The ARP 12pt Hardware Kit is engineered from ARP's renowned 8740 chromoly steel, a material celebrated for its high strength-to-weight ratio and durability. The fasteners undergo a proprietary heat treatment process that enhances their tensile strength to 180,000 psi, ensuring they can withstand extreme loads and stresses. The black oxide finish not only provides corrosion resistance but also gives the hardware a professional, finished look.

The 12-point head design allows for increased contact area with tools, enabling higher torque application and reducing the risk of stripping or rounding off the head during installation or removal. This design is especially beneficial in tight or hard-to-reach spaces where a standard hex head might be difficult to access. The precise machining and strict quality control standards ensure each fastener fits perfectly and performs reliably over time.

Performance & Reliability

Built for demanding environments, the ARP 12pt Hardware Kit offers exceptional strength and reliability. Its high tensile rating ensures a substantial safety margin, making it suitable for high-performance applications and heavy-duty use. The corrosion-resistant finish helps maintain integrity in harsh conditions, whether exposed to moisture, saltwater, or extreme temperatures. This hardware kit is designed to provide a secure, long-lasting fastening solution that supports your vehicle’s safety and performance needs.

Installation & Fitment

The ARP 12pt Hardware Kit is designed for straightforward, bolt-on installation. Its precision threads and high-quality construction mean no special tools or modifications are required.
