Rocker panels are a common and integral part of a vehicle, but most people aren't familiar with them. A rocker panel is the lower frame that connects the front and rear portions of your car, located on each side. Beyond the roof supports, these components are a primary part of a vehicle’s infrastructure and provide structural reinforcement. Because rocker panels play such a crucial role in vehicle safety and collision protection, it’s important to have them checked occasionally by an auto body repair shop for signs of damage. Here's what you should know.

Signs to Replace Rocker Panels

Because of their location, rocker panels are more susceptible to the elements from the road and especially if a vehicle is used for off-roading. The most common culprit for replacing a rocker panel is rust. Rust always starts from the inside out and expands to the surface. If the drainage holes or the surface have visible signs of significant rust, it’s safe to assume the inside is completely rusted and that the part is dissolving. In this case, an auto body repair shop can replace the rocker panel to preserve the vehicle’s structural integrity. Rocker panels that have been damaged from collisions should also be replaced, as bent or wrinkled metal compromises its ability to keep the vehicle fully intact. 

How to Keep Rocker Panels in Good Condition

The best way to take care of your rocker panels is to prevent rust from forming. You can use a rust inhibitor or rust spray at least once a year, which adds a protective coating. The chassis on the vehicle benefit from cleaning twice per month, clearing out gunk and grime on the rocker panels that may have accumulated over time. Since excess moisture can lead to corrosion, practice vigilance by looking for minor signs of rust, particularly around the drain holes and in hidden areas, such as underneath the vehicle. If you notice minor surface rust, you can use a wire metal brush to scrape it away gently. However, it’s best to consult with an auto body repair technician who can advise on the right cleaners and materials to use, additional ways to protect your rocker panels, and if they should be replaced.
