Construction & Design

The Cusco Rear Upper Arm Bushing with Boots features a robust pillow ball design crafted from high-grade, race-proven materials. The pillow balls are precision-machined to ensure a perfect fit and optimal load distribution, providing a direct connection between the suspension components and the chassis. The housing and mounting points are engineered for durability and precise alignment, ensuring that the suspension geometry remains consistent even under demanding conditions.

The inclusion of rubber boots serves a dual purpose: protecting the pillow balls from dirt and moisture while maintaining smooth movement. The design minimizes unwanted play and deflection, translating to sharper steering and improved handling response. The bushings are engineered to retain their performance characteristics over time, making them suitable for both street and track use.

Performance & Sound

By replacing the factory rubber bushings with Cusco's pillow ball design, you'll notice a more direct and responsive steering feel. The reduction in suspension deflection enhances cornering precision and stability, especially during aggressive driving or high-speed maneuvers. While these bushings are primarily focused on handling improvements, they also contribute to a more engaging driving experience with subtle, sporty feedback through the steering wheel. No specific horsepower or torque gains are claimed, but the upgrade supports your vehicle's overall performance and responsiveness.
