What is quarter panel?

A quarter panel is a body panel on the side of a vehicle that covers the area between the rear wheel and the trunk or rear door. It is usually made of sheet metal and is an important structural component that helps to protect the vehicle's occupants in the event of a collision.

Quarter panels are often prone to damage in accidents or through corrosion over time. Repairing or replacing a quarter panel can be a complex and costly process, as it involves cutting out the damaged panel, welding in a new panel, and then finishing and painting the area to match the rest of the vehicle.

Quarter panels can be customized with different designs or paint finishes to give a vehicle a unique look. They are also sometimes referred to as rear fenders or rear wings, depending on the style and construction of the vehicle.
