Cusco Strut Bar 40 Rear EF3 CIVIC

The Cusco Strut Bar Type 40 is a high-performance strut tower brace designed to bring serious chassis reinforcement to street and track builds alike. Utilizing a 40mm diameter lightweight aluminum shaft, this strut bar significantly enhances front-end rigidity, reduces body flex under load, and sharpens steering response during high-G cornering.

Engineered for enthusiasts who push their cars to the limit, the Type 40 delivers a noticeable improvement in handling precision and chassis stability. By tying the strut towers together, it allows your suspension to do its job more effectively by keeping alignment geometry consistent — especially critical when braking deep or transitioning weight quickly.

The larger 40mm shaft offers greater stiffness than Cusco's standard OS bar, while still maintaining a manageable weight profile. The Type 40 Strut Bar not only performs at a high level — it looks the part too. Whether you’re competing at the circuit or carving mountain roads, the Cusco Type 40 adds confidence, control, and a professional touch to your engine bay.
