X8R Ltd is a British company completely dedicated to providing high quality improved design vehicle components; correcting original manufacturers design faults. We take the common faults associated with a variety of vehicle manufacturer’s parts and re-design and manufacture parts that will not fail again or that will prevent damage to vehicles.
Is your vehicles air suspension rising slowly, noisily, or perhaps failing to rise at all? EAS fault message, "Warning do not exceed 35 mph" message, lights just flashing on height adjustment switch? Hard fault stored, vehicle on bump stops and not rising, taking too long to reach pressure, excessive compressor running?



The likely cause of the faults noted above and most common cause is a worn piston seal and or liner within the air suspensions compressor unit. Coupled with saturation of the filters in the compressors
filter unit. This results in reduction of compressor output and triggers vehicle faults as well as
extending the time taken to lift the vehicle.


Our complete kit includes all needed to restore your compressor to full health. Our kit includes a
new improved design piston seal constructed to the finest of tolerances from
improved materials to restore full output.
A replacement piston liner to replace your scored or damaged liner.
Full filter replacement kit to allow you to replace all filters,
the original filters saturate quickly and drastically effect output, our improved replacements will
solve this problem.
