Dedication to manufacturing and developing superior products has established Energy Suspension as the most asked-for name in performance polyurethane components today. The complex and diverse nature of Energy's proprietary Hyper-Flex(TM) material requires constant attention to developing the optimum polyurethane formulas. This devotion has produced the quality components that our customers continue to demand. Providing problem-solving solutions with applications for the most popular vehicles, paired with our Limited warranty and superb customer support, Energy Suspension is your first quality choice in performance polyurethane suspension components.Energy Suspension offers dozens of track arm bushing sets for a wide range of applications. Track arms (panhard bars) help keep the front or rear axle aligned with the centerline of your vehicle; but if the bushings holding them in place are worn, then the bar and your axle could shift left or right. Many factory bushings are made from rubber, which cracks and disintegrates over time. These replacement bushing sets from Energy Suspension are molded from durable polyurethane for long-lasting performance. Order the set recommended for your year, make, and model.
