Part #: 564 311 A21

Overview

The Cusco 21mm Front Sway Bar is a high-performance suspension upgrade designed specifically for Mitsubishi Lancer Evolution models 7, 8, and 9 (CT9A). Crafted to enhance your vehicle's handling characteristics, this sway bar replaces the factory component and mounts directly to the original locations, ensuring a seamless upgrade. Whether you're a spirited street driver, a track enthusiast, or an off-road adventurer, this sway bar helps you achieve more precise cornering and improved stability.

By upgrading to the Cusco 21mm sway bar, you'll experience a noticeable reduction in body roll during aggressive turns, allowing for more confident and controlled driving. The increased stiffness over the stock sway bar helps distribute lateral forces more evenly across the suspension, resulting in a more planted feel and better overall handling. This upgrade is ideal for those seeking to improve their vehicle's responsiveness without sacrificing ride comfort.

Key Features

The Cusco 21mm Front Sway Bar boasts several advanced features that contribute to its superior performance:

• Constructed from high-strength steel to resist torsion and maintain shape under demanding driving conditions.
• 21mm diameter provides a significant stiffness increase over the factory sway bar, enhancing body control during cornering.
• Uses the factory mounting locations, ensuring an easy bolt-on installation without the need for modifications or additional hardware.
• Designed with precision CNC-machined end links and bushings for durability and consistent performance.
• Reduces body roll and weight transfer, improving grip and handling response during spirited driving or track days.
• Maintains ride comfort by balancing stiffness and compliance, preventing harshness on everyday roads.

Construction & Design

The Cusco sway bar is engineered with a focus on durability and performance. Made from high-quality steel, it features a 21mm diameter tube that offers increased resistance to torsional forces compared to the stock component. The bar's design incorporates precision CNC-machined end links and bushings, ensuring a secure fit and consistent operation over time. Its straightforward bolt-on installation utilizes the factory mounting points, making it accessible for enthusiasts and professionals alike.

The use of steel construction not only enhances strength but also helps in effectively managing chassis roll and weight transfer during aggressive maneuvers. The design maintains a balance between stiffness and ride comfort, making it suitable for both daily driving and competitive motorsport applications.

Performance & Sound

Upgrading to the Cusco 21mm sway bar significantly improves your vehicle's handling dynamics. You'll notice sharper turn-in response, reduced body lean, and more predictable cornering behavior. While the sway bar itself does not produce a noticeable sound, the enhanced chassis stability contributes to a more confident driving experience. This upgrade supports better grip and control, especially during high-speed cornering or spirited driving sessions.

Installation & Fitment

The Cusco 21mm Front Sway Bar is designed for a straightforward, bolt-on installation using the factory mounting locations. No cutting, drilling, or additional modifications are required, making it an accessible upgrade for DIY enthusiasts and professional installers alike. The process typically involves removing the existing sway bar and end links, then installing the new Cusco component with the included hardware.
