I have had to grind down the rear wheel studs about 1/8-1/4 inch since replacing my Ford 8.8 with my YJ. Some have to replace the rear studs with longer ones on stock axles. BUT changing wheel studs is easy and worth it in some situations. I can now use a set of Fuel Revolver JK rims and they look great. Installation was easy and these spacers are recommended by one of the forums. I didn't use Loctite but if I ever need to take them off I can put them back on. I went for a retight after 100 miles and they were still tightened to spec. I definitely recommend them!
