A sagging stance, bottoming out under load or a cracked or broken coil can mean a spring is worn or damaged. Before you replace the springs, rule out worn shocks, bushings and ball joints, since those also change how a truck rides. The front axle takes one spring on each side, and this listing is the pair.
