Installation Tips !
We strongly reccommend the use of a front panhard bar (such as our 910-49801, at right) with four bar front suspensions. Four bar suspensions increase suspension travel over original wishbones or radius rods, which increases the need for side-to-side axle control. If using a Vega cross steering system, the panhard bar becomes mandatory as any side-to-side movement will cause bump steer.
