Mopar part 55055121, "Gear, Headlamp Adjusting, Vertical" in the Parts Manual. OEM part, used, in excellent condition. These fit 96-98 Jeep Grand Cherokees (Jeep ZJ). I’m a long time ZJ owner/enthusiast who personally picks these parts.  Then I clean, lube and test the operation of each one by hand to ensure that it’s going to work in your ZJ.  Every 96-98 ZJ has two horizontal headlight adjusters (not shown, see my other ad) and two vertical adjusters (short ones, as pictured in this ad) per vehicle. Includes two OE Torx mounting screws with each adjuster.  Several available, so the pics you see are representative.  Hard to find part nowadays.  Free Shipping to continental US.
