Be in control-when maneuvering through turns, during standing start accelerations, braking, and over bumps and berms. Allows the leaf spring to function more effectively. For high-performance applications, the combination of heavy duty/performance leaf springs and ENERGY´S polyurethane spring bushings deliver maximum benefit. These bushings also improve lighter-duty leaf spring systems, adding a higher degree of performance and durability. In either situation, you´ll feel the difference in positive handling and control.
