The Header Bolt Kit - 6pt. 3/8 x 1.00 UHL (16) by ARP is designed for serious engine builders and performance enthusiasts who require dependable fasteners that can withstand extreme thermal and mechanical stress. These exhaust header bolts are engineered to resist loosening and failure due to constant heating cycles and vibrations, which can lead to exhaust leaks and gasket damage.

This kit features a 6-point socket head design with a 3/8-inch diameter and a precise 1.00-inch Under Hex Length (UHL), ensuring superior grip and torque transfer compared to conventional fasteners. Manufactured from premium alloy steel and shot-peened for enhanced fatigue resistance, these bolts are built to maintain clamp load integrity across the entire header assembly, providing a reliable sealed connection.

Ideal for street and track builders, the ARP header bolts are suitable for naturally aspirated, forced-induction, and high-heat applications where standard fasteners may compromise reliability. This 16-piece set covers most common V8 engine configurations, making it a versatile choice for various engine assembly needs.
