Cusco 680 541 A Type OS Rear Strut Bar - Oval Shaft Aluminum Strut Tower Brace

The Cusco Type OS is one of Cusco's most popular and iconic strut tower braces, engineered to reduce chassis flex and deliver sharper, more confident handling. The rear strut bar connects the strut towers with a rigid aluminum structure, minimizing body flex under cornering loads and improving overall steering response.

Center Bar Construction:

• Oval shaft design — the tubular aluminum bar features a distinctive oval cross-section that provides an optimal balance of lightweight characteristics and structural rigidity
• High-polish finish — the aluminum shaft is finished to a mirror-like polish for a clean, premium appearance under the hood
• Dual-design engineering — the Type OS is available in two internal configurations: Type 1 (pressed ribbed) and Type 2 (sectioned); Cusco engineers pre-select the ideal design for each specific vehicle application

Bracket & Hardware:

• Steel end plate brackets painted in Cusco's trademarked blue finish for instant brand recognition and corrosion resistance
• Includes all required hardware for a complete bolt-on installation
• No cutting, welding, or special tools required — installs in minutes with standard hand tools

Performance Benefits:

• Reduces body flex across the chassis for more predictable cornering behavior
• Improves steering response and overall vehicle stability
• Suitable for both daily driving and performance-oriented applications

Cusco is a Japan-based performance manufacturer with decades of motorsport development experience across rally, time attack, gymkhana, and circuit racing. The Type OS strut bar reflects that engineering heritage in a clean, no-compromise bolt-on package.
