Product Description

The Cusco 694 541 A Rear Strut Tower Bar (Type OS) is engineered to increase rear chassis rigidity on select Subaru AWD platforms. By tying together the left and right rear shock towers, this brace minimizes flex during transitional cornering and high-load maneuvers, helping maintain suspension alignment and providing sharper handling feedback. The oval aluminum shaft construction balances strength with minimal weight for track and street applications.

Finished with Cusco's signature blue end plates and designed for precise fitment, this rear strut tower bar bolts directly into factory mounting points with basic hand tools. The part enhances stability and rear suspension response on 2015-2021 Subaru WRX and STI models, with additional compatibility on earlier Impreza and XV Crosstrek models, making it ideal for enthusiasts seeking improved handling performance without extensive modification.
