Hardrace Rear Reinforced Stabilizer Bushing 21mm 1998-2008 Legacy/Outback / 2002-2007 WRX/STI / 2003-2008 Forester | Durable Thermoplastic | Suspension Bushing
Overview
The Hardrace Rear Reinforced Stabilizer Bushing is a high-performance suspension component designed to replace the factory rear stabilizer bushings on select Subaru Legacy, Outback, WRX, STI, and Forester models. Crafted from advanced thermoplastic material, this bushing enhances rear sway bar stability, improving handling precision and vehicle control during high-speed driving and aggressive cornering. It is ideal for Subaru enthusiasts seeking a reliable upgrade that maintains OEM fitment while delivering a more responsive suspension feel.
Unlike traditional polyurethane bushings that can degrade or break under stress, Hardrace utilizes a state-of-the-art thermoplastic compound that offers superior resilience, self-lubrication, and resistance to oil, alkali, and ozone exposure. This engineering approach ensures long-lasting durability and consistent performance without the common issues of squeaking or premature wear. The reinforced design provides a solid connection between the stabilizer bar and chassis, translating to improved chassis rigidity and driver confidence.
For Subaru owners, this rear stabilizer bushing upgrade means enhanced stability at high speeds and during cornering, with a direct bolt-on installation that requires no modifications. Maintaining the OEM mounting points and dimensions, it preserves factory alignment and suspension geometry while delivering a noticeable improvement in rear-end response. This makes it a practical and effective upgrade for daily drivers and spirited enthusiasts alike.
