Headers represent a sizable investment, and a stock-quality bolt isn't enough to keep them sealed and secure long-term. Exhaust leaks cost power and can damage your vehicle over time. ARP's stainless 12-point header bolts solve that problem — made from premium stainless steel rated at 170,000 psi tensile strength, significantly stronger than Grade 8 steel. These bolts are highly corrosion and heat resistant for long-term reliability under the toughest underhood conditions, and they're polished to a mirror-like shine for a finished, premium appearance.
