Description
Header bolt failures are one of the most preventable causes of exhaust leaks and lost horsepower on the dyno. These Proform wedge locking bolts eliminate the common problem of fasteners backing out under thermal cycling and vibration—a critical concern when running high-RPM applications or forced induction. The wedge lock design provides positive retention without requiring safety wire or secondary fastening methods, keeping your header sealed tight and your power numbers consistent.
