LANDNOVO — Precision in Motion. Engineered by GB.

Is your Land Rover Discovery or Range Rover Sport sitting unevenly, sagging, or displaying an air suspension warning light? The culprit is often a failed air suspension compressor. The LANDNOVO LR023964 Air Suspension Compressor is a premium, direct OE-grade replacement engineered to restore your vehicle's legendary ride comfort and load-levelling performance.

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 by Hitachi, the original equipment supplier for many Land Rover vehicles. It matches the quality of the original equipment (OE LR023964) that came factory-installed on your Land Rover. This compressor is a complete drop-in replacement, designed for a straightforward installation.

Why Choose the LANDNOVO Hitachi Compressor?

The air suspension compressor is the heart of your vehicle's air suspension system. It pumps air into the air springs to maintain proper ride height, ensuring a smooth and stable ride. A failing compressor can cause sagging, a rough ride, and put immense strain on other suspension components.

This LANDNOVO compressor is a direct replacement for the original Hitachi unit. It comes complete with a new compressor relay, which must be changed during installation. Using the original brackets and pipes, it is easy to install.

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

Symptoms of a Failing Air Compressor

• Vehicle sagging – one corner, one side, or the whole vehicle sits lower than normal.
• Rough or bouncy ride – loss of cushioning, making the vehicle feel harsh over bumps.
• Compressor running constantly – the system tries to compensate for air leaks.
• Unusual noises – loud humming or grinding sounds coming from the compressor.
• Suspension warning light – the dashboard displays a suspension system warning.
• Complete suspension failure – compressor does not activate, leading to loss of ride height adjustment.

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.
• Always replace the compressor relay when installing a new compressor – this compressor includes a new relay.
• No need to reprogram the ECU, but fault codes may need to be cleared.
• 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.

Experience the LANDNOVO difference. Every component is designed with British precision, manufactured to the highest standards, and backed by our commitment to quality. Restore your Land Rover's suspension performance with confidence.

Important: Air suspension systems operate under high pressure. Professional installation is strongly recommended to ensure proper fitment, safety, and system performance. 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.
