Construction & Design

The Cusco Rear Trailing Arm Bushes feature a robust pillow ball construction, crafted from high-quality materials that resist wear and deformation. The pillow balls are precision-machined to ensure a snug fit and smooth operation, providing a direct and responsive connection between the suspension components and chassis. The inclusion of rubber boots helps prevent dirt ingress, which can cause premature wear or failure.

The design emphasizes durability and performance, with a focus on maintaining the original suspension geometry while reducing unwanted movement. The bushings are engineered to withstand high loads and aggressive driving conditions, making them suitable for both daily driving and competitive motorsport applications.

Performance & Sound

By replacing the factory bushings with Cusco's pillow ball units, you'll notice a significant improvement in steering feel and cornering precision. The direct connection reduces play and flex, resulting in more predictable handling and enhanced driver feedback. While these bushings do not increase horsepower directly, they support the full potential of your vehicle's suspension setup, allowing you to better utilize your existing powertrain.

Installation & Fitment

The Cusco Rear Trailing Arm Bushes are designed as a bolt-on upgrade, requiring minimal modification to your Subaru Impreza WRX. Installation involves removing the factory bushings and pressing in the pillow ball units, which can typically be accomplished with standard suspension tools. No cutting, drilling, or complex adjustments are necessary, and the process can be completed with basic mechanical knowledge.

For optimal results, it is recommended to have the alignment checked after installation to ensure proper suspension geometry and tire wear.
