Does this require drilling or welding?

No. This bar uses factory mounting points, so you're bolting it in place. No frame modification needed.

Will this interfere with a trailer hitch?

Check your hitch position first—this reinforcement mounts at the rear bumper attachment area. If your hitch clears the factory bumper, test-fit the bar before final tightening.

Can I paint this before installation?

Painting before install is risky—you risk chipping paint during handling and mounting. Install first, then mask and paint to match your bumper cover.
