Rocker Arms – Ford (4C3Z-6564-AA) are Genuine OEM valvetrain components manufactured by Ford to meet original factory specifications for strength, precision, and long-term reliability. These rocker arms play a critical role in the engine’s valvetrain by transferring motion from the camshaft or pushrods to the engine valves, ensuring accurate valve timing and smooth engine operation. They are a direct replacement for the factory-installed components and are essential when servicing or rebuilding the valvetrain.

Manufactured from high-strength, OEM-approved metal alloys, these rocker arms are engineered to withstand constant mechanical load, heat, and friction generated during engine operation. Ford’s strict production standards ensure precise geometry and surface finish, which helps reduce wear on valves and related components while maintaining consistent valve lift and timing. This level of accuracy is especially important for maintaining engine efficiency and preventing premature valvetrain wear.

These rocker arms are specifically matched to Ford engines originally equipped with part number 4C3Z-6564-AA. Professional mechanics benefit from exact-fit compatibility that ensures proper alignment and reliable operation during installation. DIY mechanics gain confidence knowing these components meet factory specifications and install without modification, making them suitable for high-quality engine maintenance or repair projects.

Installation is straightforward when performed according to factory service procedures, allowing the rocker arms to integrate seamlessly with the existing valvetrain assembly. Maintaining OEM valvetrain components is critical for preserving engine performance, fuel efficiency, and long-term durability.

Key benefits of the Rocker Arms – Ford (4C3Z-6564-AA):
