This listing is for the pair. If you are installing Weld or other select manufacturer's 17" wheels (and in some cases 18" wheels) on the rear of your HEMI car and have factory sway bars still installed, you will need these shortened factory sway bar end links to prevent the swaybar from hitting the rim once the suspension is loaded. The factory rear sway bar has a wide hoop built into it and the swaybar will touch the rim unless you shorten the swaybar endlinks. These endlinks are new endlinks that have been shortened in order to prevent the contact. Most aftermarket swaybars do not have this contact issue.
