Description
Header bolts are one of the most overlooked failure points in engine bay work—standard fasteners can loosen under thermal cycling and vibration, leading to exhaust leaks and lost performance. This stainless steel locking bolt kit eliminates that risk with a secure hex head design and proven locking mechanism, ensuring your header stays sealed mile after mile. If you’re building or rebuilding a GM V6 or small block Chevy engine, these bolts are the reliable, no-compromise choice.
