Before you look at my picture and get scared, please read my review. I just want to say this is a great product. These are quality parts and I would recommend them to my friends. It was risky there. I installed these wheel spacers at home in Illinois when I got home from college. I used red Loctite and torqued them all to 145 ft lbs and left my truck overnight. Later that week I drove my truck 1500 miles but made a big mistake. After you install them, drive around a bit and then re-tighten all the gaskets. I didn't because I thought a week until I'm free I'd be fine. As I pulled into my apartment parking lot, my factory bolts were shaved clean and the wheel blasted the quarter panel and it eventually rolled to one side. I ended up needing a new wheel hub and rotor which cost me about $400. Before this happened, I heard a slight clink as I changed direction, so I already knew it was coming loose. Don't make the same mistake I did. This is a great product and they make my truck look amazing. I have attached before and after photos for reference. In addition, wheel spacers are very safe when installed correctly. Please do yourself a favor and watch the installation video on YouTube to install them safely. If installed incorrectly, as I did, they can become very dangerous, so following the instructions carefully is very important. All in all, I'd do it again, but I'd install them right the first time instead of learning from my $400 mistake.
