Do I need fasteners to install this?

Factory mounting points accept bolts at the rocker attachment locations. Bolts are not included — source M6 or M8 fasteners matching your OEM hardware or refer to your vehicle service manual for the exact spec.

Can I paint this before or after installation?

Install it first, then mask off surrounding panels and paint to match your bumper cover. Primer is not pre-applied, so sand lightly and prep the surface like any bare plastic before painting.

What if this doesn't fit correctly when I test-fit it?

Test-fit without fastening first. The rail should slide into the factory rocker channels without forcing. If alignment is off, double-check that you have the right-side (passenger) rail and that the bumper cover itself is seated correctly before committing to bolts.
