General description 

XLifter

 is an advanced air-suspension controller for specified Land Rover vehicles. XLifter 

allows  you  to  take  the  air  suspension  capabilities  of  your  Land  Rover  to  the  maximum, 
making your off-roading or expedition travelling a greater experience. 

 

XLifter 

gives you more detailed control over the vehicle height settings. Raising the vehicle 

above the maximum specified (By Land Rover) “Off-road” height, helps you to tackle difficult 
terrain.  XLifter  is  not  limited  by  the  40  Km/h  speed  limit,  therefore  travelling  over  long 
stripes of sand, green lanes or gravel roads will be more manageable. Also, XLifter keeps 
selected  lift  settings  archived,  which  means  that  you  can  keep  it  as  a  selected  height 
constantly should you wish to. Lowering the vehicle, slightly, improves cornering stability 
and  aerodynamics  (which  may  add  to  fuel  consumption efficiency).  Lowering  below  the 
original access height makes it possible for the entering of low-clearance garages or ferries 
and makes cargo loading easier. 

XLifter’s

 unique self-levelling feature makes your in-car or roof top tent conditions more 

comfortable during expedition travelling.  

XLifter

  controls  are  intuitive  and  comfortable.  The  control  module  with  graphical  OLED 

display and physical buttons is optimized for off-road handling.  

XLifter

  EAS  unit  communicates  with  the  control  module  wirelessly.  Installation  to  your 

vehicle is simple and fully removable when required. 

No drilling, soldering, or in-car wiring 

is required.

  

XLifter  is  designed  for  Land  Rover®  Discovery  3  (LR3),  Discovery  4  (LR4)  and  Range 
Rover® Sport (model L320) vehicles.

 

Range Rover® L322 2007-2012 support is currently 

experimental (in development).
