One could argue that steering your truck is the most important thing you can do, aside having brakes. Once you lift your Ford Super Duty though, there's a point where the pitman arm needs to be replaced to prevent steering failure. PMF offers a Heavy-Duty Drop Pitman Arm with a new genuine FORD OEM sector shaft nut.  Please select year of vehicle for proper fitment.  These must be accompanied by a matching drop trackbar bracket for proper function.
