Cusco Strut Bar OS Front FC3S RX7 1986-1991 Mazda RX-7

  • Electroplated Finish: Silver chrome coating resists corrosion for long-term durability
  • Bolt-On Installation: Uses factory mounting points no cutting or drilling required

Product Notes

  • Torque bolts to Cusco specifications during assembly
  • Packaged in protective cardboard tube for safe transit
