Key Features

ARP Header Bolt Kits are built with several key features that set them apart from standard hardware:

• Material Excellence: Made from high-grade stainless steel, these bolts are 15% stronger than traditional Grade 8 steel, providing increased strength and durability for demanding applications.
• Corrosion and Heat Resistance: The polished stainless steel finish offers exceptional resistance to rust, corrosion, and high temperatures, making them ideal for exhaust system use.
• Compact Head Design: The bolts feature a compact head that allows for easy installation in tight, hard-to-reach spaces next to headers, ensuring a proper fit without interference.
• Variety of Head Styles: Available in 12-point and hex-style heads, these fasteners provide versatile options for different installation preferences and tools.
• Precise Threading: With a 3/8 in.-16 thread size and an underhead length of 0.750 in. (19.0 mm), these bolts are designed for a secure, snug fit that maintains clamping force over time.
• Heat and Torque Tolerance: Engineered to withstand the high temperatures and torque loads typical in performance exhaust systems, ensuring longevity and reliability.
• Polished Finish: The polished surface not only enhances appearance but also reduces surface friction, aiding in installation and removal.

Construction & Design

The ARP Header Bolt Kits are meticulously manufactured using advanced machining and finishing processes. The stainless steel construction ensures superior strength-to-weight ratio and resistance to thermal expansion and contraction. The compact head design allows for installation in confined spaces, a common challenge in modern engine bays. Each bolt is TIG-welded and inspected to meet strict quality standards, ensuring consistent performance and fitment. These features collectively contribute to a reliable fastening solution that maintains integrity under high-stress conditions.
