XLifter X2 Air Suspension EAS Level Control Tool For Land Rover Defender 110 New Gen L663, Range Rover Sport L494, And Range Rover Full Size L405 (See Fitment Years)

XLifter is an advanced air-suspension controller for Land Rover and Range Rover vehicles, enhancing your off-road or expedition travel by maximizing air suspension capabilities. It functions as an electronic “lift kit”, allowing you to adjust the vehicle’s height at the touch of a button. XLifter also automatically levels the vehicle, eliminating the need to find a flat spot while camping.
This version XLifter X2 Air Suspension Controller with the self-leveling features is designed specifically for Land Rover Defender 110 (L663), RangeRover Sport (L495), and Range Rover Full Size (L405).
The XLifter is the world’s first and only kit that allows the Land Rovers and Range Rovers to self-to level maximum tilt of approximately 3.4° in longitudinal (pitch) or 4° in traverse (roll) direction.
The XLifter contains a high-precision tilt sensor. It is calibrated once when the vehicle is at even surface. When at a camping spot, just press the button, and the XLifter levels the vehicle automatically by adjusting the height of each wheel accordingly.
This feature has been specially developed for all over-landers or expedition travelers. Roof tent or “in-car” sleeping setup? Don’t bother finding a flat spot anymore!
When you need precise and easy control of your hitch this feature is exactly for you. A desired feature – comes standard in newer models.
In contrast with standard “flat” height change, the trailer assist changes car pitch. The resulting rotational effect greatly enhances the hitch adjustment range. A great feature for car-towing trailers, two-axles trailer tire change. Or simply forget the trailer and use the feature to make your dogs jump in with ease.
Check out this quick, but self-explanatory video for details:

Temperature monitoring is a new feature brought by the XLifter X2 EAS unit. The vehicle compressor is designed for short quick burst operations, not for continuous use. When Suspension is raised and lowered extensively, demand for air refills increases. The compressor kicks in and starts to heat up. When overheated, the vehicle computer stops further operation until cooled down – without letting the user know about it. Hence we brought the temp. monitoring to the X2 model. Play it nicely. When the temperature gets to the high or critical range, let it cool down for a moment. Be nice to your Rover.

1. Start at Standard Ride Height: Apply XLifter Setting Programs ONLY WHEN IN THE LAND ROVER or RANGE ROVER IS AT FACTORY STANDARD HEIGHT! If you forget and miss this and change the height and the vehicle faults, shut the truck off, wait 10 seconds, then restart the truck. DO NOT use any other lift rods to get the truck to go higher, this will damage the suspension. If you have Johnson Rods or other lift rods installed, they MUST BE REMOVED before installing XLifter.
2. Ensure Proper Connections: Make sure all the plugs for the electrical portion are inserted FULLY. If they do come unplugged, the truck will instantly open all valves and dump all the air out of the bags and the tank without warning, then a fault will appear on the dash. If this happens, shut the truck off, recheck and plug the loose connector back in, then restart the truck.
3. DO NOT Work Underneath Vehicle Without Jack Stands: With XLifter installed, the truck will be able to activate/run/move the air suspension with the doors open. It disables the door inhibit functions. ******* DO NOT LAY ON YOUR BACK OR USE A CREEPER TO GO UNDER THE TRUCK WITHOUT THE USE OF JACK STANDS, IN CASE THE AIR SUSPENSION FAULTS AND GOES DOWN INTO SUPER DROP MODE. *******
4. Tuning Your Ride When Keeping Vehicle At A Newly-Programmed Height: If you want to keep the truck at a programmed lift setting different than "standard ride height" (e.g. Aesthetic Lift), it is highly recommended to get a 4-wheel alignment after programming is complete. You should also loosen then re-tighten all suspension arms that have rubber bushings so the bushings are in the neutral position while at the new ride height. This will improve vehicle ride and handling while at your new programmed height.
5. Calibration On Level Terrain Only: When calibrating make sure the truck is on a level and flat surface. If this is done on a slope, the truck may not be level when using the auto-level feature.
6. Self-Leveling On Uneven Terrain: If you are trying to level the truck on uneven terrain, and the small numbers that give the degrees are flashing, the truck will not be able to completely level, but It will go as far as it can to get it to as close to level as the suspension allows.
7. Vehicle Natural Rake & Leveling Under Load: Please keep in mind that trucks have a natural rake (rear slightly higher than the front), and it will level to the calibrated pitch and roll that the truck was calibrated at. Also, keep that in mind when you are using a rooftop tent on the truck, and it is fully loaded for an expedition.
