Cusco 422535A Strut Bar Type ALC OS Aluminum Carbon Fiber Strut Tower Brace

The Cusco 422535A Type ALC OS is a premium strut tower bar (also known as a strut brace or tower bar) that builds on the proven Cusco Type OS platform with an upgraded carbon fiber aesthetic. It connects the two strut towers to reduce chassis flex at one of the most critical structural points of the vehicle, helping maintain proper suspension geometry under hard cornering loads.

The bar features a twin-layer oval-section lightweight aluminum shaft wrapped in real carbon fiber, delivering an ideal balance of low weight and high torsional rigidity. The oval cross-section profile provides enhanced stiffness compared to a round tube of equivalent weight, making it a popular choice for performance and track-day use. End plates are finished in titanium gray to complement the carbon fiber bar and provide a distinctive, sport-inspired look in the engine bay.

Key Features:

• Lightweight oval aluminum shaft with dual-layer carbon fiber wrap
• Oval cross-section design for superior rigidity-to-weight ratio
• End plates finished in titanium gray to complement the carbon fiber
• Bolt-on installation using standard hand tools — no drilling or fabrication required
• Available in Type A and Type B configurations; Cusco selects the correct design per application
• Reduces strut tower flex to maintain suspension alignment under high cornering loads

The Cusco Type ALC OS is an excellent upgrade for performance enthusiasts seeking improved chassis stiffness and driver feedback, whether on the street, autocross course, or track.
