Secure Your Exhaust with ARP 12-Point Header Bolts

Ensure your headers stay tight and leak-free with the Auto Racing Products (ARP) Header Bolt Kit. Specifically designed for the Mopar Gen III Hemi 5.7L and 6.1L engines, this kit replaces your factory hardware with high-strength, 12-point stainless steel fasteners. These bolts are built to withstand the intense heat cycles of the exhaust system without backing out or rusting.

Why Upgrade Your Header Bolts?

  • 12-Point Head: Allows for easier access with a socket in tight header flange areas.
  • Stainless Steel Construction: Polished stainless steel offers superior heat resistance and prevents corrosion.
  • Perfect Fitment: Precision-engineered for Mopar 5.7L and 6.1L Hemi engines (8mm x 1.25 thread).
  • Complete Set: Includes 16 bolts to cover your entire exhaust manifold installation.

Exhaust leaks can rob your engine of power and cause performance issues. By upgrading to these premium ARP fasteners, you ensure a consistent, long-lasting seal between your headers and the cylinder head. The 12-point design is perfect for modern engine bays where space is at a premium, allowing you to tighten your headers with confidence. Don't let cheap, rusted bolts ruin the look and performance of your Hemi. Invest in the best hardware for your Mopar build with high-quality components from GGCRACING.
