Multi-link suspension systems for vehicle are described having various linkage arms that connect to distinct points of a wheel mount. Each of the linkage arms are preferably coupled to the wheel mount via a spherical ball joint and mounted such that they can independently move with respect to the other linkage arms. A shock assembly is preferably mounted between two of the linkage arms on a separate links that is configured to vary its length based on movement of one or both of the two linkage arms.

A method of mounting to an A-arm suspension system a wheel spindle configured for use with a multi-link suspension system may involve the steps of: Removing at least one suspension link mount on the wheel spindle; mounting a ball joint bracket to the wheel spindle, the ball joint bracket being configured to mount to the A-arm suspension system, the removing and mounting steps producing a modified wheel spindle; and mounting the modified wheel spindle to the A-arm suspension system.
