A vehicle includes a body structure and a frame rail assembly. The frame rail assembly extends forward from the bulkhead along a longitudinal centerline. The frame rail assembly includes a frame rail defining a rail axis and a reinforcing member. The frame rail defines a longitudinally extending seam and the frame rail extends forward from the bulkhead along the longitudinal centerline. The frame rail further defines an end portion. The reinforcing member is secured to the frame rail at the end portion to increase a stiffness of the frame rail at the end portion. The reinforcing member is configured to limit a stress at the seam, transverse to the rail axis, resulting from a load applied to the end portion of the frame rail and laterally offset from the longitudinal centerline.
