On most body-on-frame trucks, rocker panels enhance torsional stiffness, which is particularly crucial for off-roading vehicles. Given the higher ground clearance of many off-road trucks, these panels also serve as a practical step for easier vehicle entry. Truck rocker panels can be especially helpful for children, shorter adults, and the elderly when getting into taller vehicles.
3. Types of Rocker Panels: Choosing the Right Option
When it comes to replacing rocker panels, there are two main types: welded and slip-on. Each type has its own set of advantages and disadvantages, making it important to choose the right option for your needs.
3.1 Welded Rocker Panels
Welded rocker panels require welding directly onto the vehicle’s body for installation. To avoid damage, it is best practice to remove the doors and fenders before beginning this process. This ensures that the panels are properly fitted beneath the doors.
Post-installation, you’ll typically need to clean up the welds and prepare the panels for painting. Due to the complexity of the installation process, it is recommended to hire a professional mechanic if you do not have prior experience.
3.2 Slip-On Rocker Panels
Slip-on rocker panels are typically installed using automotive adhesives or fasteners. Though easier to install than welded panels, slip-on panels still require effort. Before installing the panels, you will need to remove any traces of rust and drill holes for the rivets.
One potential drawback of slip-on rocker panels is that the fasteners, screws, or rivets may loosen when driving on rough terrain. Additionally, the fastener heads can be visible along the top edges of the rocker panels, but a body filler can minimize these imperfections.
