Key Features

ARP Header Bolt Kits are built with precision and quality to meet the demands of high-performance applications. Key features include:

• Material Excellence: Made from premium stainless steel, these bolts offer exceptional corrosion resistance and heat tolerance, making them suitable for the high-temperature environment near headers and exhaust manifolds.
• Enhanced Strength: ARP stainless steel header bolts are approximately 15% stronger than traditional Grade 8 steel fasteners, providing increased reliability under stress.
• Compact Head Design: The bolts feature a compact 12-point or hex-style head, allowing easy installation in tight spaces where clearance is limited. This design facilitates tool access and reduces installation time.
• Optimized Dimensions: With a thread size of 3/8 in.-16 and an underhead length of 0.750 inches (19 mm), these bolts are engineered for a precise fit in a wide range of header applications.
• Corrosion & Heat Resistance: The polished finish not only provides an attractive appearance but also enhances resistance to rust and heat-related degradation, ensuring longevity and consistent performance.
• Versatile Compatibility: Designed for universal fitment, these header bolt kits are suitable for a variety of vehicle makes and models, especially those with custom or aftermarket headers.

Construction & Design

These header bolt kits are constructed from high-grade stainless steel, a material chosen for its excellent strength-to-weight ratio and resistance to corrosion and high temperatures. The compact head design allows for installation in confined spaces often encountered near headers and exhaust manifolds, making them ideal for custom builds and tight engine bays. The bolts are precision-machined to ensure a perfect thread fit and consistent torque application, reducing the risk of leaks or bolt failure. The polished finish not only adds a sleek look but also provides an additional layer of protection against rust and corrosion, extending the service life of the fasteners.

Performance & Reliability

While these bolts do not directly increase horsepower, their high-strength stainless steel construction ensures that your header installation remains secure under demanding conditions. Properly torqued header bolts help maintain exhaust seal integrity, which can contribute to optimal engine performance and efficiency. Their heat and corrosion resistance make them suitable for high-performance applications, spirited driving, or long-term use in harsh environments.

Installation & Fitment

The ARP Header Bolt Kits are designed for straightforward, bolt-on installation. They utilize existing mounting points and do not require modifications or special tools beyond standard socket sets. The compact head design allows access in tight engine compartments, simplifying the installation process. No cutting, drilling, or tuning is necessary, making these bolts a convenient upgrade for both professional mechanics and DIY enthusiasts.
