This OEM cylinder head lifter and push rod tray guide is designed for Ford Super Duty trucks equipped with the 7.3L gas engine from 2021 to 2026. It mounts within the cylinder head to properly position and guide the lifters and push rods, helping maintain correct valve train alignment and smooth engine operation. A damaged or worn tray guide can lead to improper push rod positioning, increased wear, or valvetrain noise. Replacing it with a new OEM guide restores proper component alignment, supports reliable valve operation, and helps protect critical engine components. Manufactured to factory specifications, this tray guide ensures precise fitment, durable construction, and dependable long-term performance.
