Premium Exhaust Security with Auto Racing Products Mopar V8 12-Point Header Bolt Kit

Achieve an unyielding, leak-proof seal for your Mopar V8 headers, especially in challenging installation environments, with the Auto Racing Products 12-Point Header Bolt Kit. This specialized kit is engineered with a 12-point head design, providing more wrenching surface and superior access in confined spaces often encountered with aftermarket headers. Crafted from high-strength chromoly steel, these bolts are designed to endure the extreme thermal cycling and vibrations of high-performance exhaust systems, preventing loosening and ensuring consistent clamping force. Say goodbye to frustrating exhaust leaks and hello to optimized engine performance and sound, even in the most demanding applications.

Enhanced Features for Mopar V8 Header Installations:

  • Robust Chromoly Construction: Each bolt is precision-engineered from premium chromoly, offering exceptional tensile strength and resistance to stretching under extreme heat and stress, ensuring long-term durability.
  • Ideal for Mopar V8 Engines: Features 5/16-18 inch thread and 0.75 inch Under Head Length (UHL), ensuring perfect compatibility with a wide range of Mopar V8 header applications, both small and big block.
  • 12-Point Head Design: Offers superior grip and easier installation/removal in tight clearances compared to traditional hex heads, a significant advantage for complex header designs and limited access.
  • Black Oxide Finish: Provides excellent corrosion resistance, protecting the bolts from rust and maintaining their integrity in demanding engine bay conditions, extending their lifespan.
  • Comprehensive Set of 14: Includes all necessary bolts to securely fasten your headers, ensuring a complete and professional installation without the need for additional hardware.

The Advantage of 12-Point Header Bolts

When space is at a premium around your Mopar V8 headers, a 12-point bolt head becomes invaluable. It allows for more engagement points with your wrench, reducing the risk of stripping and making installation and maintenance significantly easier, especially in cramped engine bays. Beyond convenience, these Auto Racing Products chromoly bolts deliver uncompromising strength, maintaining a steadfast seal against exhaust leaks that can rob horsepower and create an undesirable sound. This kit is the definitive choice for enthusiasts and professionals seeking both ease of installation and ultimate reliability for their Mopar V8 exhaust system, ensuring peak performance and longevity.
