Proven on the racetrack as well as the street, the Energy Suspension Hyper-Flex System allows you to replace your mushy rubber bushings with high-performance polyurethane versions. Domestic or import, front or rear wheel drive, 2WD or 4WD—all vehicles will achieve a higher level of performance. Hyperflex components will not break down or deteriorate from exposure to oils, undercar chemicals, or atmospheric conditions. They also improve appearance over stock and are available in several different colors to suit all of your needs, from show to go.
