Key Features

ARP Header Bolt Kits are built with advanced materials and thoughtful design features to meet the needs of performance automotive enthusiasts. Key features include:

• Superior Strength: Made from ARP's proprietary stainless steel, these bolts are approximately 15% stronger than traditional Grade 8 steel fasteners, providing increased durability and resistance to stretching or breaking under high stress.
• Corrosion and Heat Resistance: The polished stainless steel finish offers excellent resistance to rust, corrosion, and heat, ensuring long-lasting performance even in extreme engine bay conditions.
• Compact Head Design: The bolts feature a compact, 12-point or hex-style head that allows for easy installation in tight spaces often found near headers and exhaust manifolds.
• Precise Threading: The 3/8 in.-16 thread size ensures a secure fit across a wide range of applications, providing consistent clamping force and sealing integrity.
• Versatile Compatibility: Suitable for various vehicle makes and models that require 3/8 in.-16 header bolts, making them a versatile choice for many performance builds.
• Polished Finish: The smooth, polished surface not only enhances appearance but also reduces the risk of galling and facilitates easier installation and removal.

Construction & Design

The ARP Header Bolt Kits are meticulously manufactured using ARP's proprietary stainless steel alloy, which combines high tensile strength with excellent corrosion resistance. The bolts are precision-machined to exact specifications, ensuring a perfect fit and reliable performance. The compact head design allows for installation in confined spaces, a common challenge when working with headers and exhaust manifolds. The polished finish not only provides an attractive appearance but also minimizes surface friction during installation, reducing the risk of damage to the fasteners or surrounding components.

Each bolt features a fully threaded shank with a 3/8 in.-16 thread pattern, providing ample engagement and clamping force. The heat-resistant properties of the stainless steel ensure that the fasteners maintain their strength and integrity even under high-temperature conditions typical of engine operation. These design choices make the ARP header bolt kits a durable and dependable solution for high-performance and everyday driving applications alike.

Installation & Fitment

The ARP Header Bolt Kits are designed for straightforward, bolt-on installation. They utilize the factory or aftermarket header mounting points and require no modifications or special tools beyond standard socket wrenches. The compact head design allows access in tight engine bay spaces, simplifying the installation process. No cutting, drilling, or tuning is necessary, making these bolts an easy upgrade for both professional mechanics and DIY enthusiasts.
