Do these covers use factory bolts or do I need new fasteners?

They bolt at factory points, so you'll use your existing door handle hardware. Test-fit before final assembly to confirm bolt alignment with your specific truck.

Can I paint these or should I leave them raw?

The smooth finish accepts paint well if you want to match your truck color. If you're leaving them unpainted, wipe them down before install to remove any dust from storage.

Will these fit my door handles without any trimming or modification?

They're designed as a direct bolt-on to factory mounting points with no cutting. Verify fitment at the door handle base before committing to fasteners — door panels vary slightly between model years.
