What Are Rocker Panels?

Rocker panels are visible on the outside of all cars bodies. They are easy to find once you know where they are, but the term "rocker panel" has an obscure origin.

Identification

Rocker panels are the parts located under a car's doors and between the tire wheels. Each car has two, and they are usually painted the same color as the rest of the car.

Function

Traditionally, rocker panels were used to protect the undercarriage of a car from rocks, mud and other road debris.

Misconceptions

Rocker panels do not have anything to do with the rocker arms used in the automotive engine.

Prevention/Solution

You can add splash guards behind each wheel to prevent rocker panel damage from road debris kicked up by the tires.

Fun Fact

First used on race cars, car manufacturers now modify rocker panels by adding aerodynamic effects and side skirts to the panels on some cars.
