both the front and the rear are very easy to install. the front has 6 mounting points, and the rear has four. took me about 2 hours for both. save yourself some money and do it. t&h sends instructions along with them.
where can i get a good price for the bars? tonight some yup with an x5 parked right up against my rear bumper... luckily i have the rear camera so i could back up and get out of the parking spot without hitting the beemer. i think those bars will make people think twice before parking so close to my truck.
