The spring is the undeniable heart of the suspension system, yet the spring can only "store" energy but can not "absorb" it. The Eibach Pro-Damper Kit was designed to work with the Eibach Pro-Kit, recognized worldwide as the No. 1 performance suspension spring. Though the Eibach Pro-Kit is designed to perform well in conjunction with O.E. dampers, the Eibach engineers recognized the additional advantage of developing their Pro-Damper Kit, specifically valved (tuned) to match the unique characteristics of the Pro-Kit. Eibach Pro-Kit and Eibach Pro-Damper...in perfect harmony. Eibach Pro-Damper Set priced from $252.00 to $708.00.
