AIR SUSPENSION - GENERAL SPECIFICATION
| ITEM | SPECIFICATION |
|---|---|
| Ride height: | |
| Off road 1 | 40 mm above standard. |
| Off road 2 | 75mm above standard. |
| Access - reselectable while vehicle is moving | 50 mm below standard. |
| High speed | n/a |
| Trim height | Configured using the Land Rover approved diagnostic system. |
| Height sensors: | |
| Front location | Mounted to the front suspension towers with mechanical linkages to the upper suspension arms. |
| Rear location | Mounted to the rear suspension sub-frame with mechanical linkages to the lower suspension arms. |
| Height sensor operating voltages: | |
| Supply voltage | 5 volts - supplied by air suspension control module. |
| Output voltage | Left-hand front and left-hand rear: Voltage increases with compression and decreases with rebound. Right-hand front and right-hand rear: Voltage decreases with compression and increases with rebound. |
| Spring/damper module types: | |
| Front | Guided air spring surrounding mono-tube damper. |
| Rear | Unguided air spring, separate mono-tube damper. |
| Pressures: | |
| Normal - Front | 800 to 1000 kPa (8.0 to 10.0 bar) (116.0 to 145.0 lbf/in2 ) |
| Normal - Rear | 500 to 800 kPa (5.0 to 8.0 bar) (72.5 to 116.0 lbf/in2 ) |
| Air supply unit: | Comprises a piston compressor, 12 volt electric motor, solenoid operated exhaust pilot valve, combined slave exhaust valve and pressure relief valve, and air dryer unit and a temperature sensor. |
| Controlled by | Air suspension control module. |
| Working pressure | 1650 kPa (16.5 bar) |
| Maximum pressure | 2200 kPa (22 bar) |
| Air reservoir: | |
| Volume | 11 liters |
| Nominal working pressure | 1525-1650 kPa) |
| Maximum operating pressure | 2200 kPa (22 bar) (319 lbf/in2 ) |
| Valve blocks: | |
| Front | 2 corner valves, 1 cross link valve - all mounted on RH inner wing panel, between the main bulkhead and secondary bulkhead. |
| Rear | Incorporates pressure sensor to monitor spring and air reservoir pressures, reservoir valve, 2 corner valves, 1 cross link valve - all mounted on the upper rearward RH side of the spare wheel well, beneath rear load space carpet. |
