1. A cross-linked system comprising:
a first shock assembly;
a second shock assembly;
a first line fluidly coupled with a rebound chamber of the first shock assembly and a compression chamber of the second shock assembly, to allow fluid to flow between the rebound chamber of the first shock assembly and the compression chamber of the second shock assembly;
a second line fluidly coupled with a compression chamber of the first shock assembly and a rebound chamber of the second shock assembly, to allow fluid to flow between the compression chamber of the first shock assembly and the rebound chamber of the second shock assembly;
a reservoir, wherein the reservoir is fluidly coupled to the first line and the second line;
a first roll damping valve fluidly coupled with the reservoir and the first line, said first roll damping valve to restrict fluid flow heading towards the reservoir, wherein said first roll damping valve is an active valve;
a second roll damping valve fluidly coupled with the reservoir and the second line, to restrict fluid flow heading towards the reservoir; and
a heave damping valve, fluidly coupled to the reservoir, the first roll damping valve, and the second roll damping valve, to restrict fluid flow in at least one direction.
