Product Description

The Cusco 1C2 311 A28 is a 28mm high-strength hollow steel front sway bar engineered specifically for the 2020-2026 Toyota GR Supra A90/A91 platform. It replaces the factory 24mm front anti-roll bar with a thicker, stiffer unit that delivers a 194% increase in roll resistance over stock. This dramatic improvement in front roll stiffness translates directly to reduced body roll during hard cornering, sharper turn-in response, and increased high-speed directional stability - transforming the GR Supra's already capable chassis into an even more confidence-inspiring platform for spirited street driving and competitive motorsport.

The bar is constructed from hollow high-strength steel to maximize torsional rigidity while keeping weight to a minimum. It is finished in Cusco's signature blue powder coat for a professional appearance and long-term corrosion protection. The kit includes polyurethane bushings and steel mounting brackets, making it a complete bolt-on replacement for the OEM bar with no vehicle modification required. Installation takes approximately one hour using basic hand tools and can be performed on a lift or with the vehicle safely supported on jack stands.

For optimal front-to-rear balance, Cusco recommends pairing this front sway bar with their corresponding rear sway bar (1C2 311 B22, 22mm, sold separately), which increases rear roll stiffness by 178% over the OEM 18mm rear bar. Together, the front and rear sway bar combination delivers a balanced and predictable handling profile that reduces understeer and improves overall chassis composure under all driving conditions. This sway bar fits both the 2.0L Turbo and 3.0L Turbo GR Supra across all model years, including the facelifted 2023+ A91 variants.
