Installed on the rear of a 1980 GMC K2500. The shocks being replaced were probably original and long overdue for replacement. As a (retired) professional mechanic I've always had good luck with the KYB line of products and they certainly perform as expected. KYBs were boxed for Carquest. The product comes with a top mounting bolt for the frame, but you must save and reuse the bottom mounting bolt on the axle.
