Increases tire clearance to allow installation of wider wheels and tires. [FITMENT NOTE] Not compatible with OEM wheels. The included lug nuts, along with your OEM wheel studs, will extend past the surface of the spacer. Please verify that the back of the wheels have "pockets" / cavities large enough to accommodate for this. Every 3/4" (20mm) spacer on the market will have this issue; if your wheel is unable to accommodate for the protruding nut/stud, we recommend looking at thicker spacers.
