ARP 3/8″ x .750″ Stainless Steel 12-Point Header Bolt Kit
The ARP 400-1208 3/8″ x .750″ Stainless Steel 12-Point Header Bolt Kit is the premium upgrade for securely mounting exhaust headers on Ford, GM, Chrysler, and other V8 engines. Manufactured from high-strength stainless steel with a polished finish, these bolts offer superior corrosion resistance in harsh under-hood environments while providing the clamping force needed to prevent leaks and maintain gasket integrity under high heat and vibration. The shorter .750″ length is ideal for applications with limited header flange thickness or tight clearance. The 12-point head design allows for better wrench access in confined spaces, making installation and removal far easier than conventional hex bolts.
