H&R offers this Super Sport series of springs for those wanting maximum lowering. Depending on application, watch 1.75-2.3 inches of drop make your fender well gap disappear. Progressive rate coil design keeps the ride smooth, even at these lower ride heights. Cold wound, high tensile strength spring steel that is beautifully powder coated for extended performance and life. It is definitely not recommended to use such a short spring with your original, or replacement type shocks. Poor performance and shock wear will occur. We suggest Bilstein B8 or Koni Sport (Yellow) shocks and struts for these springs.
