Citro n’s innovative hydropneumatic suspension system’s unique characteristics introduce stresses into other areas of the suspension system, and with the cars sitting on their bump stops for prolonged periods when parked, the rubber bump stops soon compressed, and with age essentially disintegrated. Due to its superior durability, and improved performance and longevity qualities over rubber, polyurethane makes the perfect replacement, Made using our Dark Grey Heritage 80A durometer material to retain the look of the OE rubber, this bump stop features a concave design on the lower face, to allow for mounting within warped retaining cups which often make aftermarket replacement impossible.
