Cusco 564311A21 21mm Front Sway Bar with Bushings

The Cusco 564311A21 is a 21mm front sway bar (stabilizer bar) engineered to significantly reduce body roll and sharpen handling dynamics. Replacing the factory sway bar with this larger-diameter Cusco unit provides greater torsional resistance, helping keep the chassis flat and stable during hard cornering while maintaining everyday ride quality.

Key Features:

• 21mm diameter — larger than the OEM bar for increased stiffness and reduced body roll
• High-strength steel construction — resists torsional flex for consistent, predictable handling
• Direct bolt-on installation — uses factory mounting locations with no modifications required
• Includes all necessary hardware — bushings and end-link hardware included for a complete installation
• Signature Cusco blue finish — corrosion-resistant painted finish for lasting durability and clean underhood appearance
• Tunable handling balance — front sway bar upgrades help reduce understeer and sharpen cornering response

Unlike stiffer spring or damper upgrades that can compromise ride comfort, a higher-rate sway bar reduces lateral weight transfer and body lean with minimal impact on daily driveability. The Cusco 564311A21 is ideal for street performance driving and track use where flat, controlled cornering is essential.
