Engineered for reliability and durability, this kit is designed to prevent header bolts from loosening due to extreme heat and vibration common in performance applications.

Key Features:

  • Application: Specifically designed for Ford 5.0L 4V Coyote engines.

  • Stage 8 Locking System: Utilizes a unique locking mechanism that actively prevents bolts from backing out, even under severe conditions.

This kit is essential for any Mustang or F-150 owner pushing the limits of their Coyote engine.
