Vehicle with chassis height adjustment having floating strut rods

A vehicle, comprising:

• a chassis comprising at least one axle;
• a plurality of wheels supporting the chassis;
• a plurality of suspension modules, each suspension module coupling one of the plurality of wheels to the at least one axle, and each suspension module comprising:
• a module frame pivotably connected to the at least one axle;
• a wheelbox mounted to the wheel and slidingly mounted to the module frame by first and second strut rods, the wheelbox and module frame being configured to pivot in unison with respect to the chassis, wherein the module frame is configured to move between a first operating position and a second operating position relative to the wheelbox;
• and
• an adjustment actuator coupled with the module frame and configured to shift the module frame between the first operating position and the second operating position, wherein the first and second strut rods move from a first position in which bottom ends of the first and second strut rods are below the wheelbox when the module frame is in the first operating position to a second position in which the bottom ends are in a higher position relative to the first position when the module frame is in the second operating position.
