Will this bolt straight onto my Nitro, or does it need trimming?

This mounts at factory rocker and bumper points with no drilling or trimming needed. Test-fit before final fastening to confirm alignment with your specific vehicle.

Does this come with mounting hardware?

The valance itself ships as-is. You'll need standard fasteners to secure it to the factory mounting points — check your vehicle's service manual for the correct bolt size and torque specs.

Can I paint this, or does it come primed?

Hard panel construction is ready to prep and paint. Sand lightly, apply primer, then finish with your color of choice to match the rest of your bumper.
