Review on Rugged Ridge 1.75-Inch Wheel Spacer Kit for 2005-2018 Wrangler, Grand Cherokee, and Commander by Tyrone Carter

spacers fit JK 2013 no problem. Remove windows, remove rust/dirt and install. They fit right onto the vehicle, so don't plan on just putting them on. I put anti-seize material in between to make it easier to remove when it's time to swap out the rotors. Don't forget to remove the rotor mounting washers. I had two on each side in the front but none in the back.
