Do these covers work with the factory door handles or do I need new handles?

These covers bolt right over your factory handles — no replacement needed. They're designed to wrap around what's already there and secure with fasteners.

Will the chrome finish hold up to salt and weather?

Chrome steel is built to resist oxidation, but regular washing — especially after salt exposure — keeps the finish looking its best. Avoid abrasive cleaners that can scratch the surface.

What tools and fasteners do I need to install these?

Mounting hardware is not included with this set. Check your factory door handle assembly for existing bolt patterns, then source fasteners that match — most hardware stores stock standard options for this application.
