3. The system of claim 1 , wherein the at least one actuator system module comprises at least one pump and at least one accumulator.

4. The system of claim 1 , wherein the at least one mounting plate is fixed to the subframe using at least one bolt.

5. The system of claim 1 , comprising:

a second hydraulic suspension actuator comprising a piston, a first upper fluidic chamber, and a second lower fluidic chamber, the first and second fluidic chambers of the second hydraulic suspension actuator being separated by the piston of the second hydraulic suspension actuator;

a second longitudinal beam located laterally between the second hydraulic suspension actuator and the at least one actuator system module; and

at least one second conduit fluidly connecting the second hydraulic suspension actuator and the at least one actuator system module, wherein the at least one second conduit passes over the second longitudinal beam.

6. The system of claim 5 , wherein the at least one second conduit comprises a first conduit fluidically connecting the first upper fluidic chamber of the second actuator to the at least one actuator system module and a second, separate conduit fluidically connecting the second lower fluidic chamber of the second actuator to the at least one actuator system module.

7. The system of claim 5 , wherein the first and second hydraulic suspension actuators are associated with a common axle of the vehicle.

8. A vehicle comprising at least one system as claimed in claim 1 .

9. A system for a vehicle comprising:

a hydraulic suspension actuator comprising a piston, a first upper fluidic chamber, and a second lower fluidic chamber, the first and second fluidic chambers being separated by the piston;

at least one actuator system module mounted to a subframe and laterally separated from the hydraulic suspension actuator, the at least one actuator system module comprising one or more actuator system components; and

at least one conduit fluidly connecting the hydraulic suspension actuator and the at least one actuator system module, wherein the at least one conduit is configured to pass over a longitudinal beam of the vehicle located laterally between the hydraulic suspension actuator and the at least one actuator system module, and

wherein the subframe comprises an aperture and the at least one actuator system module is mounted to the subframe in the aperture via at least one mounting plate that protrudes below an upper surface of the subframe.

10. The system of claim 9 , wherein the at least one conduit comprises a first conduit fluidically connecting the first upper fluidic chamber to the at least one actuator system module and a second, separate conduit fluidically connecting the second lower fluidic chamber to the at least one actuator system module.

11. The system of claim 9 , wherein the at least one actuator system module comprises at least one pump and at least one accumulator.

12. The system of claim 9 , wherein the at least one mounting plate is fixed to the subframe using at least one bolt.

13. The system of claim 9 , comprising:

a second hydraulic suspension actuator comprising a piston, a first upper fluidic chamber, and a second lower fluidic chamber, the first and second fluidic chambers of the second hydraulic suspension actuator being separated by the piston of the second hydraulic suspension actuator;

a second longitudinal beam located laterally between the second hydraulic suspension actuator and the at least one actuator system module; and

at least one second conduit fluidly connecting the second hydraulic suspension actuator and the at least one actuator system module, wherein the at least one second conduit passes over the second longitudinal beam.

14. The system of claim 13 , wherein the at least one second conduit comprises a first conduit fluidically connecting the first upper fluidic chamber of the second actuator to the at least one actuator system module and a second, separate conduit fluidically connecting the second lower fluidic chamber of the second actuator to the at least one actuator system module.
