Bilstein 7100 Series Classic are the most successful shock absorber in off-road racing history. Since their inception in the early 70's, these dampers have equipped more winning off-road cars and trucks than any other shock. Today, the 7100 Series Classic are perfect for meeting the demands of vintage off road race cars and off-road recreational vehicles such as Baja Bugs and Sand Cars. The 46mm monotube gas pressure construction and the self adjusting deflective disc valving make these an ideal choice for any off-road enthusiast. They come with 1/2" spherical bearings on each end along with 12mm step down spacers to fit traditional mounting configurations. 7100 Series Classic shocks absorbers are equipped with a high flow piston to dramatically reduce harshness and give the level of performance you have come to expect from Bilstein. These shocks are 100% factory rebuildable and come in the traditional yellow painted finish.
