Dual, diagonal bars to reduce vehicle roll and pitch rates, thereby stabilizing the vehicle, are disclosed. One bar attaches linking the left front suspension to the right rear suspension, and the other bar links the right front suspension and the left rear suspension. Attachment points link alternate corners rather than being on the same axle. The bars are attached to the suspension with additional attachment to either the suspension or the chassis. The primary means of mounting, or attaching, the bars is in at least four spots for each bar. There may be a need to add one additional mount, or more, per bar along the long section of the bar between the front and rear chassis mounts to control flex and provide a more pleasant ride. The opposing end of the bar is attached to the rear suspension outboard near the spring mount on a live rear axle, or on the control arm of an independent rear suspension. A sleeve could replace the two mounts that are on the suspension. An alternate method of mounting the bars is to have the bars effectively mounted in two places along each suspension arm, thereby causing the bar to act as a torsion bar.
