EHC (Electronic Height Control)
With this lift system the pre-load (height of the car) on the spring can be changed from inside the car. Intrax developed a compact hydraulic pump with which the preload adjusters can be changed in length which will change the height of the car. Offered for the front but can also be fitted on front and rear shocks.
By adding EHC as an extra option, the height can be adjusted from inside the car. This can have the advantage that the bumper no longer touches the ground at steep angles in a garage, for example, that higher speed bumps can be taken without any problems, that entry becomes easier, that the normal driving position can be lower and much more.
