Abstract: A front suspension for a front axle of a tractor of an articulated vehicle may include an upper suspension link having an axle center mounting arm pivotally connected proximate a top side of the front axle at the axial center of the front axle, and first and second frame mounting arms extending rearward and pivotally connected to a tractor frame of the tractor. The frame mounting arms may be positioned symmetrically with respect to the axial center of the front axle. The front suspension may further include first and second lower support links pivotally connected proximate a bottom side of the front axle, extending rearward from the front axle, and pivotally connected to the tractor frame. The lower support links may be positioned symmetrically with respect to the axial center of the front axle.
