Do these come with mounting bolts or clips?

Caps only. You'll use your existing factory hardware at the wheel hub to secure them in place — verify your current fasteners are in good condition before install.

Will these fit both front and rear wheels on a dually?

Front and rear caps are different sizes. Order the correct set for your position or confirm both fitments before checkout if you need a full set.

Can I paint or customize these caps?

ABS accepts paint, but prep with a scuff and primer designed for plastic. Clean with soap and water, light sand with fine grit, then prime and paint. Test adhesion on a small area first.
