What Is A Quarter Panel?
Quarter panels are exterior metal body panels that define how the rear of your vehicle will look to the eye. Because rear quarter panels provide structural support, they are typically welded in place on vehicle assembly lines. Some quarter panels are one large piece that serves both as a rear fender and roof section while others seem to qualify more as rear fenders because they have no roof sections integrated. On a few makes and models, some rear quarter panels are available in partial sections.
