The Superpro rear sway bar mount bushing for 1979 Mazda RX-7 GS (rear, 21 mm) is a direct-fit replacement that renews sway bar anchoring and improves body control by replacing worn OEM mounts. Built to match factory hardware and geometry, this bushing restores more precise handling and reduces the loose feeling caused by degraded rubber mounts, making suspension response more consistent over time.
