Get rid of your weak, stock upper A-arms and ball joints, and replace it with Camburg's uni ball upper A-arms with massive 1" uniballs. Stock F-150's have relatively weak upper A-arms and ball joints that are not well suited for off road use, but by replacing them with Camburg's performance A-arms and uni balls your F-150 will have a stronger suspension and a more solid ride. Although well suited for off road use they still provide an excellent ride quality while on the street.
*MUST use rims with no more than 5" of backspacing, some stock rims with not fit.
