The present embodiments provide an adjustable toe suspension arm for a vehicle. The suspension arm includes a main suspension bracket coupled to the vehicle's chassis. An outer swing bracket is pivotably coupled to the main suspension bracket. An adjustment mechanism is coupled to the main suspension bracket. A sliding nut is coupled to the adjustment mechanism. A portion of the sliding nut is contact with the outer swing bracket. When the adjustment mechanism is manipulated, the sliding nut moves to rotate the outer swing bracket with respect to the main suspension bracket.
