ARP S/S Header Bolt Kit - 3/8 x .750 UHL (12) 400-1207

Header bolts are mission-critical fasteners that endure extreme thermal cycling and vibration in high-performance engines. OEM bolts often corrode, seize, or fail under sustained heat and pressure—compromising both reliability and ease of future service. ARP's stainless steel header bolts eliminate corrosion concerns while delivering the clamping force and durability your engine demands.

This 12-piece kit covers a full header installation with fasteners engineered to stay tight. The polished stainless construction resists oxidation and heat damage, while the 12-point head design maximizes wrench compatibility and reduces the risk of rounding during installation and removal. Whether you're building a street machine or race engine, these bolts provide the precision and longevity that serious builders expect.
