Air Suspension Compressor - AMK-type compressor assembly from the air suspension supply circuit, for vehicles with four-corner air suspension.

The compressor draws air through the intake filter and delivers it under pressure to the valve block, which distributes air to the individual air springs and, where fitted, to the system reservoir. It runs on demand under control of the suspension ECU to raise ride height, level the vehicle and restore working pressure.

Supplied as a complete compressor assembly.

Frequently asked questions

What does the T4K14386 air suspension compressor do?
This AMK compressor supplies the four-corner air suspension. It draws air through its intake filter and feeds the valve block, which distributes pressure to the air springs and reservoir. It fits the Discovery 5 (L462), New Defender (L663) and Range Rover (L405).
What Land Rover part number does this replace?
This compressor corresponds to Land Rover number LR140034, with cross-references LR140034G and LR140034W. It's the AMK four-corner air suspension compressor, so confirm your car has four-corner air suspension rather than coil springs before ordering.
What are the signs of a failing air suspension compressor?
A tired compressor typically shows as slow ride-height changes, a car sitting low after parking, or a suspension fault warning on the Range Rover or Discovery. Compressors often fail from worn piston seals or from overworking to feed a leaking air spring.
Does this fit a New Defender?
It fits the New Defender (L663) MHEV and PHEV variants with four-corner air suspension, plus the Discovery 5 (L462) and Range Rover (L405). Confirm your vehicle has the four-corner air system, as coil-sprung cars don't use this compressor.
