A rocker panel on a Jeep (or any vehicle) is the section of the body located between the front and rear wheel wells along the sides of the vehicle, just below the doors. Use our step-by-step guide to explore Jeep Rocker Panels. They server several key functions:
The rocker panel is a critical structural component that helps reinforce the frame of the vehicle. It contributes to the overall rigidity of the body, which is especially important in off-road vehicles like Jeeps that need to withstand torsional stresses.
2. Protection
Rocker panels provide a layer of protection against road debris, rocks, and other hazards that can be kicked up while driving. This is particularly important in off-road conditions where the underbody of the vehicle is more likely to come into contact with rough terrain.
3. Aesthetic Component
Beyond its functional roles, the rocker panel also contributes to the vehicle’s overall appearance, providing a clean line along the lower edge of the body.
4. Mounting Point for Accessories
On Jeeps, rocker panels often serve as mounting points for aftermarket accessories like rock sliders or step bars. Rock sliders are heavy-duty steel bars that protect the rocker panels from damage during off-road driving, while step bars provide a convenient step to help passengers get in and out of the vehicle.
5. Rust and Corrosion
Rocker panels are prone to rust and corrosion over time, especially in regions where salt is used on roads during winter. Rust can compromise the structural integrity of the rocker panels, so it’s important to inspect and maintain them regularly.
If a rocker panel becomes damaged or rusted, it’s important to address the issue promptly to prevent further damage to the vehicle’s body and to maintain the structural integrity of the vehicle.
Replacements or repairs can involve welding new panels in place or using rust treatment products to prevent further deterioration.
Jeep rocker panels come in various types, each designed to serve different purposes, from basic protection to heavy-duty off-road use. Here are the different types of Jeep rocker panels:
1. Factory (OEM) Rocker Panels
Description: These rocker panels are the standard original components for Jeeps. They are typically constructed from sheet metal to seamlessly blend with the vehicle’s body, both in terms of appearance and functionality.
Purpose: They provide basic structural support and protection against minor road debris but may not be strong enough for extensive off-road use.
2. Aftermarket Replacement Rocker Panels
Description: These panels are designed to replace the factory rocker panels, often used when the original panels have become rusted or damaged. They are usually made from similar materials as the OEM panels but might be slightly thicker or have additional rust-resistant coatings.
Purpose: These are ideal for restoring a Jeep’s appearance and maintaining its structural integrity after the original panels have deteriorated.
3. Rock Sliders
Description: Rock sliders are heavy-duty steel or aluminum bars that mount to the side of the Jeep along the rocker panels. They are designed to protect the rocker panels from severe damage during off-road driving.
Purpose: These are essential for off-road enthusiasts who frequently navigate rocky terrain. Rock sliders absorb impacts from rocks and other obstacles, preventing damage to the rocker panels and the vehicle’s body.
4. Rocker Guards
Description: Rocker guards are reinforced plates or bars that attach to the rocker panels for added protection. They are typically made from thick steel or aluminum and may extend slightly outward to shield the lower part of the vehicle.
Purpose: Similar to rock sliders, rocker guards offer enhanced protection for the rocker panels during off-road adventures. They are particularly useful for preventing dents, scratches, and rust caused by debris.
5. Tubular Rocker Panels
Description: These rocker panels feature a tubular design, often combining the functions of both rocker panels and side steps. They provide a rugged appearance and offer additional protection along the vehicle’s sides.
Purpose: Tubular rocker panels are popular for their dual functionality, providing both protection and a convenient step for easier vehicle entry and exit. They are commonly used on off-road Jeeps for added durability.
6. Bolt-On Rocker Panels
Description: Bolt-on rocker panels are aftermarket panels that can be easily installed without welding. They typically come with pre-drilled holes and mounting hardware, making them a convenient option for DIY enthusiasts.
Purpose: These panels are designed for ease of installation and are ideal for those looking to replace or upgrade their rocker panels without the need for professional welding services.
7. Custom Rocker Panels
Description: Custom rocker panels are tailored to fit specific needs or aesthetic preferences. They may be made from various materials, including steel, aluminum, or even carbon fiber, and can be designed to match the overall look of a modified Jeep.
Purpose: These are for Jeep owners who want a unique appearance or specific functionality that standard rocker panels don’t offer. Custom panels can be designed for enhanced protection, style, or both.
8. Integrated Rocker Panels with Steps
Description: These rocker panels incorporate a built-in step for easier access to the vehicle. They are often made from reinforced materials to provide both protection and functionality.
Purpose: Integrated rocker panels with steps are ideal for Jeep owners who need a durable solution that also adds practicality, particularly for lifted vehicles or those frequently used in off-road settings.
Each type of rocker panel is suited to different needs, from basic factory replacements to heavy-duty protection for serious off-roading. Choosing the right type depends on how you use your Jeep and the level of protection you require.
Jeep Rocker Panels FAQs
1. What is the purpose of rocker panels on a Jeep?
Answer: Rocker panels provide structural support to the vehicle’s chassis, helping to maintain the overall rigidity of the body. They also protect the lower sides of the vehicle from road debris, dirt, and damage, especially during off-road driving. Additionally, they serve as mounting points for accessories like rock sliders and side steps.
2. How can I tell if my Jeep’s rocker panels are rusted or damaged?
Answer: You can check for rust or damage by visually inspecting the rocker panels for signs of corrosion, dents, or cracks. Pay special attention to areas where the paint may be bubbling or flaking, as these can indicate rust beneath the surface. Tapping the panel lightly with a tool can also help reveal weak spots where rust may have compromised the metal.
3. Can jeep rocker panels be repaired, or do they need to be replaced?
Answer: Minor rust or damage to rocker panels can often be repaired with patch panels or rust inhibitors. However, if the damage is extensive, especially if the rocker panel is structurally compromised by severe rust or dents, it will likely need to be replaced. This involves cutting out the old panel and welding in a new one.
4. What are rock sliders, and how do they relate to rocker panels?
Answer: Rock sliders are heavy-duty bars or plates that mount to the rocker panels to protect them from damage during off-road driving. They are designed to absorb impacts from rocks, logs, and other obstacles, preventing dents and scrapes to the rocker panels and, by extension, the vehicle’s body. They also provide a reinforced surface that can support the vehicle’s weight if it slides over obstacles.
5. How do I maintain the rocker panels on my Jeep?
Answer: To maintain your Jeep’s rocker panels, regularly clean them to remove dirt, mud, and road salt, which can lead to rust. Inspect them periodically for signs of rust or damage. Applying a rust-proof coating or undercoating can help prevent corrosion, especially in areas with harsh winters or where off-roading is frequent. If you notice any rust or damage, address it promptly to prevent it from worsening.
