A system and methods are provided for a suspension system of an off-road vehicle that allows the springs to be mounted remotely, in any location on the vehicle, enabling the use of spring sizes, spring rates, motion ratios, and damping profiles that would be impractical with traditional suspensions. The suspension system includes a hydraulic cylinder coupled between the wheel and the chassis, in lieu of a conventional spring. This cylinder is in fluid communication with another cylinder by way of a hydraulic hose. This second cylinder includes a piston that presses against a suspension spring that is in contact with a fixed spring stop, thus transferring spring forces to the wheel. Alternatively, the spring stop may comprise a control actuator that moves according to signals from an onboard computer control system, enabling active control over spring load and chassis attitude.
