Cusco 404570A Type Front Strut Tower Bar D-Shape Aluminum - 40D

The Cusco 404570A Type 40D Strut Tower Bar is a front strut brace engineered from high-tension aluminum with a distinctive D-shaped cross-section and a polished finish. Unlike a traditional round-tube strut bar, the flat side of the D-profile reduces the bar's overall profile, making it an ideal solution for engine bays where clearance is limited.

Constructed with a 40mm OD aluminum pipe, the D-shaped geometry retains excellent torsional rigidity to resist chassis flex under hard cornering and aggressive driving conditions. Steel end-plate brackets finished in a titanium gray color provide secure, precise mounting to the strut towers. All required mounting hardware is included, and installation requires only basic hand tools.

Key Features:

• High-tension aluminum D-shaped center bar — 40mm OD
• Polished bar finish with titanium gray steel end-plate brackets
• Slimmer profile than the standard Cusco Type 40 round-tube bar — designed for tighter engine bay clearances
• 2-point bolt-on design — no permanent modifications required
• Improves front-end stability and sharpens turn-in response
• Includes all hardware necessary for installation
• Manufactured by Cusco Japan (Carrosser Co. Ltd.)

The Type 40D is part of Cusco's strut tower bar lineup and bridges the gap between rigidity and fitment versatility. It is a direct bolt-on upgrade that delivers measurable handling improvements without requiring professional installation.
