High performance 2005-10 Mustang suspension bushings from Energy Suspension and Prothane offer improved handling and steering response. They are available to replace just about any stock rubber bushing on the Mustang that you can think of, such as control arms, sway bars, end links and more. Polyurethane 2005-10 Mustang suspension bushings are direct replacements for the stock soft rubber bushings that often deteriorate and cause a soft spongy feel.
