S/S Header Bolt Kit - 3/8 x .875 UHL (12)

The S/S Header Bolt Kit - 3/8 x .875 UHL (12) from ARP is designed for engine builders and mechanics focused on header installation or replacement. This kit includes high-quality stainless steel fasteners that are suitable for various applications, including both street and competition use.

Manufactured from premium stainless steel, this kit features 3/8-inch diameter bolts with an 0.875-inch under-head length (UHL), ensuring compatibility with standard header flange bolt holes. The material is resistant to corrosion and galling, which are common issues when installing fasteners in tight exhaust manifold spaces.

This 12-piece kit is ideal for single or paired header installations on small-block and mid-size engines where 3/8-inch fasteners are the factory standard. Whether upgrading a classic muscle car or a modern performance vehicle, these bolts provide the reliability needed for secure header attachment.
