Land Rover Air Suspension Parts & Compressors

About Land Rover Air Suspension

Air suspension replaces or supplements steel springs with air springs that inflate and deflate to hold a set ride height, level the vehicle under load, and on many models raise or lower the car for access and off road clearance. This collection sits within our wider Land Rover suspension parts range and groups every air specific component: air springs and air struts, air suspension compressors, air dryers and reservoirs, valve blocks and levelling valves, ride height sensors, EAS control modules, pressure switches, and the pipes, connectors and clips that link them. Hydraulic active roll control hardware, such as ACE and Dynamic Response lines and active anti-roll bar parts, is listed here too where fitted. Those are related chassis parts rather than pneumatic air parts.

Conventional coil springs, road springs and shock absorbers are not air parts, so those belong in the coil springs and shock absorber collections. One point worth keeping straight: an air strut combines an air spring with a damper, so an air suspension vehicle still has a damping function. It does not run without one.

Buying Guide and Fitment Scope

Land Rover and Range Rover air systems differ by platform, so match the part to the exact model and build. Late high specification Range Rover Classic models gained factory electronic air from 1992 to 1996. The Range Rover P38 from 1994 to 2001 introduced full four corner EAS. The Range Rover L322 from 2002 to 2012, L405 from 2013 to 2022 and L460 from 2022 onwards all run four corner air. The L322 uses passive anti roll bars with a pneumatic cross link valve in the air system for off road articulation, while hydraulic active roll control, badged Dynamic Response, was fitted to some L405 and L460 specifications. Range Rover Sport L320 from 2005 to 2013, L494 from 2014 to 2022 and L461 from 2023 onwards use the same four corner approach, and many carry hydraulic active roll control, known as ACE on the L320 and Dynamic Response on the later cars.

The Discovery 2 from 1998 to 2004 can use rear self levelling air springs on SLS equipped models rather than a full four corner system, while Discovery 3, 4 and 5 run four corner air on most specifications. The New Defender L663 from 2020 onwards offers electronic air suspension on air equipped builds. Base and commercial Discovery 3 and 4 versions were built with coil springs, so confirm your vehicle actually has air before ordering.

Genuine air suspension parts carry the Land Rover part number. OEM or OES parts come from original equipment manufacturers or recognised OE suppliers, and brands such as Dunlop, Continental, WABCO, Hitachi and AMK may appear as OE, OES or aftermarket depending on the specific item, while specialists such as Arnott are aftermarket. On early L322, Discovery 3 and early Discovery 4 the original Hitachi compressor was later superseded by an AMK unit under a Land Rover service update, so check which type your car needs. For owners who would rather leave air behind, air to coil conversion kits swap the air springs for steel coils and are also listed in this collection.

How to Confirm the Right Part

Air parts are build sensitive. Before ordering, take the VIN from the base of the windscreen or the chassis plate and use it to confirm the exact platform, model year and whether the vehicle left the factory with air or coil springs. A VIN check returns the build specification, which tells you which compressor, valve block or air spring variant your car uses, since several models changed supplier and part number during the production run. Ride height sensors and air springs are handed left and right, or split front and rear, so match the position as well as the model.

Common Fitting Notes

Replace air springs as an axle pair where practical, because a fresh spring next to a tired one gives uneven response and wear, and the older spring is usually close to age related failure. A compressor that runs long or has burned out has often been overworked by a leaking air spring or a failed valve seal, so check the springs and pipe joints as the root cause before assuming the compressor alone is at fault. Fit new air line collets and O rings whenever you open a connection, and calibrate ride height once everything is back together. These are practical fitting notes rather than a full repair procedure.
