Abstract: A lower arm of a vehicle suspension includes a base defining: a knuckle assembly configured for a knuckle and ball joints to be coupled thereto, a front assembly configured to be coupled to a front side of a vehicle body, and a rear assembly configured to be coupled to a rear side of the vehicle body. The knuckle assembly, the front assembly, and the rear assembly define a plane. The front assembly includes a pipe member coupled to the base. A first cross-section of the base is defined by a first center part that curves below the plane defined by the assemblies, a first wall portion extending downward from the first center part, and an end portion extending inward from the first wall portion.
