Heavy-Duty Exhaust Fasteners for Big Block Engines

When you are running a Big Block Chevy or Ford, you need hardware that can handle the increased heat and vibration of a high-displacement engine. The Auto Racing Products S/S Header Bolt Kit provides the ultimate solution for securing your headers. These bolts are manufactured from premium stainless steel, ensuring they remain tight and rust-free throughout the life of your exhaust system.

Engineered for Performance

  • Thread Size: 3/8-16
  • Under Head Length (UHL): 0.750 inches
  • Material: High-strength stainless steel
  • Head Style: Hex head
  • Quantity: Set of 16 bolts
  • Fitment: Big Block Chevy and Ford engines

The 0.750-inch under-head length is the industry standard for most aftermarket headers, providing the perfect balance of thread engagement and clearance. Unlike factory-style bolts, these stainless steel units will not seize in the cylinder head, making future header swaps or gasket replacements much easier. The polished finish provides a clean, professional look that stands up to the harsh environment of the engine bay. Whether you are building a street-strip machine or a dedicated race car, these bolts provide the peace of mind that your exhaust system is secure. Don't let a loose header bolt ruin your day at the track; upgrade to this reliable fastener kit today. Find all the high-performance hardware you need for your next build at GGCRACING.
