Here is what Speedway has to say:There is some controversy surrounding the use of a Panhard rod on cross spring drop axle suspension systems . While there are many hotrods running around without one most of the top chassis builders feel that it is a necessary part of a front suspension , especially with a 4 bar . With an original buggy spring and wishbone setup , the triangle shape of the wishbone limited side to side motion .Even a split wishbone or radius rod front end with the axle mounting points wider than the frame mounting points provides some measure of triangulation to help control side motion . By its design the four-bar front end is engineered to allow the front suspension to travel freely ( thus providing better ride quality and handling characteristics ) but it can not control side to side motion . The problem is compounded by cross- steering , as any side to side movement WILL cause bump steer . A Panhard bar should be considered mandatory on all four-bar systems and recommended on all cross steer systems . While building my ride every rod I looked at had one , so I put one on mine. LFE
