Having trouble keeping your Ford driving straight? Alterations like installation of a suspension lift or levelling kit can cause the steering pivot axis and tire position to swing rearward, resulting in wandering, wobble, pulling and stiff steering. By installing the BD Diesel Performance Cam Caster Adjustor Kit on the radius control arms of the Ford 2005-2010 Super Duty pick-ups, correcting the caster to a more positive angle is made easier and helps prevent a number of potential steering problems.
