Abstract
Abstract A vehicle suspension system comprising a knuckle arm supporting a wheel, upper and lower arms connecting the knuckle arm to a frame of a vehicle body, and a radius rod and a stabilizer each having an end attached to the lower arm in the vicinity of an end thereof connected to the knuckle arm. The lower arm has an attachment aperture defined therethrough substantially longitudinally of the vehicle body. Either the radius rod or the stabilizer is coupled to one of upper and lower surfaces of the lower arm, the other being inserted in the attachment aperture and coupled to the lower arm therein.
