Header Bolt Kit - 6pt GM 3.8L V6 5/16-18x7/8

The Header Bolt Kit - 6pt GM 3.8L V6 5/16-18x7/8 from Stage 8 Fasteners is designed for automotive enthusiasts and mechanics working on exhaust systems for third-generation Chevrolet V6 engines. This kit is particularly useful when installing performance headers, as factory fasteners can fail due to thermal cycling and vibration stress, leading to leaks and loose bolts.

The kit features six-point locking bolts that utilize a proprietary design to prevent loosening caused by vibrations, ensuring a secure fit without adding friction to the bolt hole. The bolts are sized with a 5/16-18 thread specification and a length of 7/8 inch, specifically tailored for GM 3.8L V6 header flanges, which helps maintain proper clamp load distribution across the gasket sealing surface.

Ideal for owners of Chevrolet Lumina, Monte Carlo, and other GM models equipped with the 3.8L V6, this header bolt kit is perfect for those installing aftermarket headers or replacing worn factory fasteners. Mechanics will appreciate the precision engineering that enhances reliability during header work, contributing to improved exhaust flow and engine performance.
