Do I need fasteners to install these fenders?

Installation hardware is not included with these panels. You'll need to source fasteners appropriate for your mounting approach — either bolt-on or adhesive mounting depending on your setup. Check your vehicle's OEM fender attachment points to determine fastener type and count needed.

What prep work is required before painting?

Sand the surface with appropriate grit to achieve a smooth base, then clean thoroughly to remove all dust. Apply your chosen primer and topcoat system once the surface is clean and dry. Proper surface prep ensures paint adhesion and a factory-quality finish.

Will these fit with my current fender-mounted hardware and trim?

Over fenders add extension to the stock profile. Before installation, verify that your current door trim, side mirrors, and any aftermarket ducting or cooling lines clear the new fender geometry. Measure the installed width and depth to confirm fitment with your specific setup and any other body modifications you have in place.
