These are replacement sway bar end links for guys running tall leveling kits or extended travel upper a-arms. These are 1/4" to 1" longer than stock to prevent the endlinks from rotating past the center point on full suspension extension. These will work on all of the Nissan truck platforms. These ship ready to install on the Titan/Armada platform, to fit on Frontier/Xterra/Pathfinder they will need to be adjusted to the shortest setting and one link rotated....very easy to do. See the last pic.
