Product Details

ARP 434-1202 Stainless Steel Header Bolt Kit

Header Bolts

ARP manufactures premium grade bolt kits to facilitate installation of exhaust headers in both stainless steel or black oxide (8740 chrome moly steel). The Stainless 300 material is not affected by corrosion or extreme heat, making it ideal for the application. What's more, the compact 12-point nut version lets you easily slip a socket close to the pipe. Each ARP bolt kit includes the specific number of parts for your application, plus premium-quality washers and hex or 12-point nuts, as required. Both the black oxide finished chrome moly and stainless steel are rated at 170,000 psi. Specially drilled ''NASCAR'' models available for those who wish to safety wire their header bolts to prevent loosening.
