This product does not fit a 2008 JK. The primary installation location as specified in the instructions ends up being over top of the plastic conduit at the top of the inside of the tailgate - of course that doesn't work. The alternate location is over the vents at the bottom of the inside of the tailgate - also wouldn't work. Vertically adjusting the installation location to compensate still produces a less-than-ideal installation, as the JK's tailgate placement relative to the body is different than earlier body types. When extended, the stopper does not contact the body an inch or so to the right of the edge of the body, as shown in the photos. Instead, on a JK, it contacts the body at the very edge, where the rubber gasket is. I would expect this problem to present itself on other model year JKs as well. Before you buy this, go look at your tailgate - if it doesn't look like the one in the photos, the stopper won't install well.
