Do I need to remove my current bumper to install this?

Yes—you'll need to take the bumper off to position the reinforcement bar behind it, then reinstall everything. It bolts to the existing mounting structure, so there's no drilling involved.

Will this work with an aftermarket front bumper?

This bar mounts at factory points. If your aftermarket bumper uses the same mounting location, you're good. If it has a different setup, test-fit before committing to installation.

Does this need paint before I install it?

Paint is optional. Most buyers leave it unpainted since it sits behind the bumper and stays hidden. If you want it finished for appearance or corrosion protection, prep and paint before bolting it down.
