Will this work with an aftermarket bumper?

This panel is designed around the factory bumper geometry and mounting points. If your bumper has different positioning or valance height, you'll need to test-fit before committing—the gap profile may not align.

Do I need to paint this before installation?

The panel arrives in primer-ready finish. Most builders paint it off the truck to match bumper color, then install—gives you cleaner results than trying to mask around trim after it's mounted.

What hardware do I need to bolt this on?

The filler uses your factory anchor points, but the exact fastener spec isn't included with the panel. Pull your service manual for torque specs and bolt size—takes ten minutes to confirm what you already have in your toolbox.
