Left Side Head Gasket 22-20 Ford Super Duty

The Left Side Head Gasket 22-20 Ford Super Duty (MPN 55516) is a critical engine sealing component engineered for diesel and gasoline Ford Super Duty trucks from the 2022–2020 model years. This OEM-specification gasket forms the high-pressure seal between the cylinder head and engine block on the left bank, preventing coolant and combustion gases from escaping into the oil galleries and vice versa. Proper head gasket integrity is non-negotiable in heavy-duty truck operation—any breach compromises engine reliability and can lead to catastrophic overheating or internal corrosion.

This gasket is manufactured to OEM specifications and designed to withstand the extreme thermal cycling and combustion pressures characteristic of Ford's modern PowerStroke diesel and gasoline engines. The material composition and thickness (0.35 inches) provide reliable sealing across repeated temperature swings from cold starts to sustained highway cruising. Installation requires proper torque sequencing and the use of fresh fasteners to ensure even clamping load distribution across the head surface, which is critical for long-term seal performance in trucks subjected to towing, hauling, and sustained load duty.

Ford Super Duty owners and certified technicians rely on this left-side head gasket during routine engine maintenance, head removal for repair, or after overheating events that may compromise the original seal. This is a direct fit for 2022–2020 Ford Super Duty models and must be paired with corresponding right-side gaskets and fastener kits for complete head gasket set replacement. Installation is recommended only for experienced mechanics with proper torque wrenches and a factory service manual, as improper installation can result in engine damage and costly repairs.
