Eibach developed Pro-Dampers specifically to complement the unique characteristics of Eibach Pro-Kit and Sportline springs, taking full advantage of the increased spring rate and lowers center of gravity. The result is enhanced performance throughout the entire working range of the suspension. Eibach engineers tuned Pro-Damper damping characteristics to achieve maximum performance, but without excessive stiffness or ride harshness. This precise tuning takes time and suspension expertise - a commitment Eibach undertakes to produce a damper worthy of its name. Eibach Pro-Dampers are the ultimate in shock absorber tuning and technology.
