Hardrace Pillow Ball Rear Knuckle Bushing Trailing Arm Side Fits Most Subaru Models | Precise Control | Suspension Upgrade
Overview
The Hardrace Pillow Ball Rear Knuckle Bushing for the trailing arm side is designed to enhance suspension precision and driver feedback across a wide range of Subaru models. This upgrade replaces the factory rubber bushings with a high-quality pillow ball joint, delivering a more direct connection between the suspension components and chassis. Ideal for enthusiasts seeking improved handling response and stability without compromising daily drivability, this bushing is a solid choice for both street and spirited driving.
Engineered with a combination of high molecule plastic tubing and a specific metal alloy for the inner bushing, this component balances durability with precise articulation. The outer bushing features a TPV material anti-dust boot that offers 100% resistance to dust, water, and oil, significantly extending the service life compared to OEM parts. Hardrace’s attention to material selection and construction ensures a reliable upgrade that maintains suspension geometry while enhancing feedback.
For Subaru owners, especially those driving WRX, STI, Forester, Legacy, Impreza, Outback, Crosstrek, BRZ, and GR86 models within the specified years, this pillow ball bushing translates to sharper steering response and a more connected driving experience. By reducing deflection in the rear knuckle trailing arm, it improves control and stability during cornering and aggressive maneuvers, making it a practical performance enhancement that complements other suspension modifications.
