Trekline Motorsport's coil springs are wound from the highest quality spring material available. They are then stress relieved and shot peened to extend the fatigue life. After manufacturing, the drop coils are powdercoated to offer rust protection and exceptional looks. These lowering springs are guaranteed NOT to sag over time! Coil springs and load tested to ensure the proper height will be achieved once they are installed.
