1. A cross-link suspension apparatus, comprising:
a first outer cylinder;
a first inner cylinder configured to be disposed within the first outer cylinder;
a first manifold including one or more apertures;
a second outer cylinder;
a second inner cylinder configured to be disposed within the second outer cylinder;
a second manifold including one or more apertures;
a first transfer tube and a second transfer tube that are configured to be coupled to the one or more apertures of the first manifold and to the one or more apertures of the second manifold;
a third outer cylinder;
a third inner cylinder configured to be disposed within the third outer cylinder;
a third manifold including one or more apertures;
a fourth outer cylinder;
a fourth inner cylinder configured to be disposed within the fourth outer cylinder;
a fourth manifold including one or more apertures; and
a third transfer tube and a fourth transfer tube that are configured to be coupled to the one or more apertures of the third manifold and to the one or more apertures of the fourth manifold,
wherein the first and second transfer tubes are configured to transfer, together as a first group, at least one of first hydraulic fluid or gas dependent on a pressure difference between the first inner cylinder and the second inner cylinder; and
wherein the third and fourth transfer tubes are configured to transfer, together as a second group independent of the first group, at least one of second hydraulic fluid or second gas dependent on a pressure difference between the third inner cylinder and the fourth inner cylinder.
