Hardrace Pillow Ball Trailing Arm Bushing Fits Most Subaru Models | Enhanced Steering Response | Suspension Upgrade
Overview
The Hardrace Pillow Ball Trailing Arm Bushing is a precision-engineered suspension component designed to replace the factory rubber bushings in the trailing arms of various Subaru models. This upgrade provides significantly improved driver feedback, sharper steering response, and a more solid suspension feel, making it ideal for enthusiasts seeking enhanced control and stability without sacrificing daily drivability. Compatible with a broad range of Subaru vehicles including WRX, STI, Forester, Legacy, and Outback models from the early 2000s to mid-2010s, this bushing is a direct OEM replacement that fits seamlessly into your existing suspension setup.
Hardrace’s design philosophy centers on durability and precision. The inner bushing incorporates a high molecule plastic tube combined with a specific metal alloy to ensure high strength and reliability under demanding conditions. The outer bushing features a TPV material anti-dust boot that offers 100% resistance to dust, water, and oil, extending the lifespan of the component. This combination of materials and engineering results in a high-quality spherical joint bearing that delivers consistent performance and longevity.
For Subaru owners, upgrading to pillow ball bushings in the trailing arms translates to a more connected driving experience. The solid response and reduced compliance in the suspension allow for better control during aggressive cornering and spirited driving. This upgrade is especially beneficial for those who want to improve chassis feedback and steering precision while maintaining OEM fitment and reliability. Whether on the street or track, the Hardrace pillow ball trailing arm bushings enhance the overall handling characteristics of your Subaru.
