2006 F-150 2" wheel spacers. Easy installation. I twisted the wire around the front of the rotors and around the stock wheel studs, hoping for better balance. They worked great! I like the new stance and the aggressive look. I also used threadlock on the factory bolts before tightening them to 150 ft-lbs. I've attached a before and after picture to show what you can expect. Currently. Let's see how long the wheel bearings last with the extra pressure.
