The Rugged Ridge Receiver Hitch Kit with Wiring Harness is easily installed with custom design bolts that hook onto the rear of the car via the factory mounting points. In fact, it look and feels very similar to the factory built receiver hitch but with more strength. It is rush free due to the durable powder coat that allows the water to fall right off of it. It is one piece making it stronger and a simple assembly process.
I bought this kit (2in receiver and 4-pin trailer wiring harness) for my 2007 JKU-X.
Install was relatively easy, but you'll get along much better if you loosen the 6 bolts holding the plastic rear bumper cover on before you get started. The hitch pictured has welded nuts, but mine actually came with loose nuts and washers, so loosening the bumper cover gives you much more wiggle room to line up and start the nuts.
The black finish on the receiver appears to be good quality with no noticeable blemishes. Time will tell how it holds up to the elements, but it should do as well as any.
The wiring harness was very nice. The push clips line right up with the factory holes in the frame, and the jumper style tail light connector install was painless. My only concern is that the dust cover for the plug is made out of rigid plastic instead of flexible rubber as is typical for this kind of thing... We'll see how that holds up after multiple on/off cycles.
I plugged my trailer into the newly installed harness and verified that everything worked as it should. No problems at all.
For the price, the relatively easy install, and the factory-like integration, I'm not sure you could find a better option than this hitch package.
