I installed a set. I had to take my truck in to have the overloads removed because there wasn't enough room vertically for both. I took me about 3hrs to do the job. Like with most things it's really a snap but since it was the first time I spent more time trying not to make a mistake than actually doing the job; a few beers didn't speed up the process either. Dealer charged me 1hr labor to remove the overloads.
