Overview

The Cusco Pillow Ball Upper Arm Rear Body Side Bushing is a high-performance suspension component designed to enhance the handling and stability of your Toyota GT86, Subaru BRZ, or Subaru GR86.

The pillow balls are made from high-strength materials to withstand the rigors of racing and spirited driving, providing a stable and precise connection. The rubber boots serve as a protective barrier against dirt, water, and debris, ensuring the pillow balls remain in optimal condition over time. The design emphasizes minimal deflection and maximum strength, translating to improved handling and steering feel without sacrificing ride comfort or durability.

Performance & Sound

Upgrading to Cusco pillow ball bushings enhances your vehicle's suspension response, offering more immediate feedback and improved steering feel.
