I really can’t remember. I believe they are 1” in the front “non hub centric” as the front hubs are still plenty long for the wheel to slide over and 2” or 3” in the rear “hub centric”. These are all the adapter style spacers like Tooljunkie mentioned. You will have to grind off some of your original studs as they will stick out past the spacer and hold the wheel from seating properly on the hub. We also had to purchase all new shallow lug nuts so they would be completely recessed in the adapter as well.
