[Modernrenovations]

Im getting ready to order 285/75/17 for the factory wheels. From my understanding a 2" spacer is needed for between the what are you guys using? Steel or aluminum

I used a 2" steel spacer from motorsport tech. Good ol'murican made one. stay away from the amazon ones.

I'm using them on same size tires on my factory Alcoa wheels.
