Let’s explore the factors influencing the cost of rocker panel replacement and how you can ensure a durable and visually pleasing outcome with auto body repair, rust repair and collision repair services.

1. What Are Rocker Panels and Why Are They Important?

Rocker panels, sometimes called “rockers,” are essential structural components that provide strength and stability to your vehicle’s body. They prevent the middle section from collapsing and offer protection during collisions.

• Structural Reinforcement: Rocker panels are crucial for maintaining the structural integrity of your vehicle.
• Collision Protection: They help protect the cabin from deformation during a collision, ensuring passenger safety.
• Aesthetic Appeal: Rocker panels contribute to the overall appearance of your vehicle.

2. Where Are Rocker Panels Located On Your Vehicle?

Rocker panels are located on each side of your vehicle, beneath the doors, between the front and rear wheel openings. They connect the front and rear portions of the vehicle, forming the bottom edge of the cabin capsule.

• Position: Underneath the doors, between the front and rear wheel openings.
• Function: Connects the front and rear of the vehicle, forming the cabin’s lower edge.

3. What Types of Rocker Panels Are Available?

There are two main types of replacement rocker panels: welded and slip-on. Each type has its own advantages and disadvantages.

• Welded Rocker Panels:
