Overview

The Cusco 18mm Rear Sway Bar is a high-performance suspension upgrade designed specifically for Honda Civic Type R (EK9) and Civic EK4 models. This sway bar replaces the factory component (if equipped) and is engineered to enhance your vehicle's handling dynamics. Whether you're a spirited street driver, a track enthusiast, or an off-road adventurer, this sway bar helps deliver improved stability and cornering performance.
