Do not buy I did a little research and the reviews were half off so I ignored the bad reviews and ordered them anyway. I tightened them to spec and re-tightened them after 100 miles. And let's say after 3 months they ripped 5 of the 6 studs off my hub while I was driving, luckily there was no one in the car and I was driving at low speed when the spacers ripped off my studs and my truck fell to the ground. Earth. And ruined my bike, $300 for a new hub, $200 for a new rim, $400 for a hitch and $100 for a new rotor, do yourself a favor and save your money and your life.
