Note:
Your Factory wheel studs may extend past the surface of the wheel spacers. In this case you will need to:
1) Shorten the factory studs
2) The wheels need to have the open slots (cavities) between mounting holes.
3) Purchase a set of shorter studs and replace them with the factory studs.

Package Including:
4 Wheel Spacers + 24 Wheel Lugs
