Cusco 157571A Type 40D D-Shape Aluminum Strut Tower Bar Brace

The Cusco Type 40D Strut Tower Bar (Part # 157 571 A) is a high-performance chassis brace engineered from lightweight, high-tension aluminum with a distinctive D-shaped cross-section. The 40mm D-profile delivers exceptional rigidity to resist chassis flex while providing the slim clearance profile needed for tight engine bay fitments where a conventional round-tube bar would not fit.

The polished center bar pairs with titanium gray steel end plate brackets for a clean, purpose-built appearance. The steel end mounts are application-specific, ensuring precise and secure fitment at the strut towers. All necessary hardware is included for a straightforward bolt-on installation using common hand tools—no cutting, welding, or fabrication required.

Key Features:

• 40mm D-shaped aluminum center bar — engineered for maximum rigidity in a low-profile form factor
• High-tension aluminum construction — lightweight without sacrificing stiffness
• Polished center bar finish with titanium gray steel end plates
• D-shaped cross-section designed specifically for tighter engine bay clearances
• Bolt-on installation — all required hardware included, installs in minutes with hand tools
• 2-point mounting across the front or rear upper strut towers
• Manufactured by Cusco Japan (Carrosser Co. Ltd.) to strict OEM-grade standards

The Type 40D is ideal for performance-oriented drivers looking to improve chassis rigidity, sharpen turn-in response, and enhance overall handling precision. Cusco strut tower bars are developed and tested on actual vehicles, ensuring real-world performance gains.
