The Cusco 18mm rear sway bar for S13 240SX is a dedicated rear anti-roll bar sized for S13 platforms to reduce body roll and enhance cornering balance. It installs as a direct replacement for the stock rear bar on S13 240SX models and helps the suspension resist roll under load, providing more predictable mid-corner behavior for street and light track use.
