Superior Locking Power for Your Headers

Don't let loose header bolts compromise your engine's performance. The Stage 8 Header Bolt Kit is designed to provide a permanent, vibration-proof seal for any application requiring 3/8-16 x 1-inch hardware. With a 12-point head design, these bolts provide superior clearance and a high-end aesthetic, making them the preferred choice for engine builders and performance enthusiasts.

Product Highlights

  • Thread Size: 3/8-16
  • Length: 1 inch
  • Head Style: 12-Point
  • Material: Nickel-Plated Steel
  • Quantity: 16-Piece Set

Stage 8’s innovative locking system is the most reliable way to keep your headers tight. The system uses a simple, effective bridge and clip that locks the bolt head in place, ensuring it cannot rotate. This eliminates the need for constant maintenance and prevents the common exhaust leaks that cause power loss and engine bay damage. The nickel-plated finish provides excellent corrosion resistance, ensuring these bolts look as good as they perform for years to come. Whether you are working on a custom project or a daily driver, these bolts offer the reliability you need to push your vehicle to the limit. Shop the full range of Stage 8 hardware at GGCRACING.
