LANDNOVO — Precision in Motion. Engineered by GB.

Is your Ford Expedition or Lincoln Navigator sitting unevenly, sagging at the rear, or displaying an air suspension warning light? The culprit is often a failed air suspension compressor.

The LANDNOVO Difference

LANDNOVO is a premium automotive brand with a distinct British engineering heritage, crafted for discerning drivers who demand nothing but the best for their vehicles. Every LANDNOVO component is Designed by GB — a mark of British precision, quality, and durability.

This air suspension compressor is manufactured to the highest standards, matching the quality of the original equipment (OE 1L1Z5319AA) that came factory-installed on your Ford or Lincoln. It is a complete drop-in replacement, designed for a straightforward installation.

Why Choose the LANDNOVO Compressor?

The air suspension compressor is the heart of your vehicle's air suspension system. It inflates or deflates the air springs as needed to maintain proper ride height. A failing compressor can cause sagging, a rough ride, and put immense strain on other suspension components.

This LANDNOVO compressor features an integrated air dryer that removes all moisture and humidity from the air system, preventing corrosion and ensuring long service life. The heavy-duty motor delivers reliable performance, and the epoxy-coated finish provides superior corrosion resistance.

Instead of paying dealership prices, the LANDNOVO compressor provides the same OE-level reliability at a fraction of the cost.

Installation Tips

• Professional installation is highly recommended for this component.
• Before installing a new compressor, inspect and repair any air leaks in the air suspension system. The main reason a compressor fails is because there is a leak in the air suspension system causing the compressor to overwork and "burn out".
• Before installation, inspect all air lines and fittings for cracks, kinks, or other damage.
• Ensure the air suspension system is properly depressurized before removing the old compressor.
• After installation, the air suspension system should be professionally tested for leaks using diagnostic equipment.
• Inspect related components including the air springs, valve block, and ride height sensors for wear or damage.
• The integrated dryer removes all moisture and humidity from the air system that cause corrosion.

Before replacing the compressor, verify there are no leaks elsewhere in the system. Any leak compromises the functioning of the compressor and the entire air suspension system.
