Polyurethane Bushing Kit

These bushings are constructed from SuperPro's proprietary, engineering-grade polyurethane formula, a material significantly more durable than rubber. This upgrade aims to enhance vehicle handling and performance while maintaining a comfortable ride. Unlike soft rubber OE bushings that degrade over time and can negatively impact control arm performance, SuperPro's polyurethane bushings offer greater resistance to wear and tear. They are unaffected by common automotive fluids, extreme temperatures, and water, ensuring consistent performance in various conditions. The material's inherent stiffness, when properly designed, leads to corrected or maintained steering geometry, improved tire wear, increased safety, and overall enhanced performance and fuel efficiency. SuperPro has focused on minimizing the Noise, Vibration, and Harshness (NVH) often associated with polyurethane upgrades. Through careful design and research, they ensure that their bushings provide enhanced control without compromising ride quality. The inclusion of knurling on the bushings is a specific design element that helps retain grease, reducing maintenance requirements and further extending the lifespan of the components. This kit includes 4 bushings, 2 metal sleeves, and 4 washers. It is backed by SuperPro's Lifetime Warranty. Applications include 2008 - 2010 Subaru Forester, 2007 - 2011 Subaru Impreza WRX, 2003 - 2012 Subaru Legacy, 2013+ Subaru BRZ, and 2017 - 2020 Toyota 86.
