Mopar part 55055121, "Gear, Headlamp Adjusting, Vertical".   OEM part, used, in excellent condition.  Hard to find nowadays.  Several available, so the pics you see are representative. Each piece has been individually cleaned, lubed and tested for operation. These fit only 96-98 Jeep Grand Cherokees (Jeep 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. Free Shipping to continental US.  As of 2024, there's another eBay Seller selling these and using my exact ad pictures, without permission.  We are not affiliated.  I am a long time ZJ owner/enthusiast who personally picks these parts.  Then I clean, lube and test each one by hand to ensure that it's going to work in your ZJ.  The other seller is a high volume parts outfit out of New York.
