Understanding Your 2003 Supercrew Rocker Panels
Before diving into the installation, let’s understand what rocker panels are and why they’re important. Rocker panels are the structural components running along the bottom of your truck’s cab, between the front and rear wheels. They provide rigidity to the body and protect the underside from road debris, water, and salt.
On the 2003 Ford F-150 Supercrew, the rocker panels are particularly susceptible to rust due to their exposure to the elements. Rust weakens the metal, compromising the structural integrity of your truck. Replacing them not only improves the appearance but also prevents further damage.

Types of Rocker Panels
There are generally two types of rocker panels:
- Full Rocker Panels: These panels replace the entire rocker panel from the door jamb to the wheel well. They offer the most comprehensive repair but require more extensive work.
- Slip-On Rocker Panels: These panels slide over the existing, damaged rocker panel. They are easier to install and a more cost-effective solution for less severe rust damage. This guide focuses on slip-on panels.
Assessing the Damage
Before buying any parts, inspect the damage. Determine how extensive the rust is. Use a screwdriver or body hammer to gently tap along the rocker panel. If the metal crumbles or feels soft, it needs replacement. Also, check the inner rocker panel for any rust, as that will need attention as well. If the rust has spread to other structural components, you might need more extensive repairs.

Step 1: Preparation – Safety First!
Before you begin, ensure your truck is parked on a level surface. Engage the parking brake and chock the rear wheels. Use a jack to lift the side of the truck where you’ll be working, and secure it with jack stands. Never work under a vehicle supported only by a jack.
Step 2: Removing the Old Rocker Panel
- Assess the Situation: Examine the old rocker panel and identify the areas affected by rust. Determine the extent of the damage.
- Remove Obstructions: Detach any components that might interfere with the installation. This might include removing the door trim, mud flaps, and any other accessories attached to the rocker panel.
- Cut Away the Old Panel: Using your angle grinder with a cutting disc, carefully cut away the rusted portion of the old rocker panel. Follow the lines where the new slip-on panel will overlap the existing metal. Be cautious not to cut into any other parts of your truck.
- Grind Down the Edges: Use the angle grinder with a grinding disc to smooth the edges of the remaining metal. This will create a clean surface for welding the new panel.
- Clean the Surface: Use a wire brush to remove any rust, dirt, and loose paint from the remaining metal. A clean surface is essential for a good weld.
Step 3: Preparing the New Slip-on Rocker Panel
- Test Fit: Before welding, test fit the new slip-on rocker panel to ensure it fits correctly. Make any necessary adjustments.
- Mark and Trim: If the new panel is too long, trim it to match the existing rocker panel’s length. Use your measuring tape and marker to mark the cut lines. Use the angle grinder to make the cuts.
- Clean the New Panel: Clean the new panel with a wire brush to remove any protective coating or debris.
- Position the Panel: Slide the new rocker panel over the remaining portion of the old rocker panel. Ensure it sits flush and aligns properly.
Step 4: Welding the New Rocker Panel
This is where your welding skills come into play. If you’re not comfortable welding, consider having a professional handle this part. Safety is paramount when welding; always wear a welding helmet, gloves, and protective clothing.
- Tack Welding: Start by tack welding the new panel in several places to hold it in position. Space the tack welds evenly along the top and bottom edges.
- Check Alignment: Double-check the alignment of the panel after tack welding. Make sure it’s straight and flush with the surrounding body panels.
- Weld the Seams: Once you’re satisfied with the alignment, weld the seams along the top and bottom edges of the new panel. Use a series of short welds to minimize heat distortion. Allow the welds to cool between passes.
- Weld the Ends: Weld the ends of the rocker panel to the existing body structure. This will secure the panel and provide structural integrity.
- Grind the Welds: After the welds have cooled, use the angle grinder with a grinding disc to smooth the welds. This will create a seamless transition between the new and old metal.
Step 5: Finishing and Painting
- Apply Body Filler: If there are any imperfections or gaps, use body filler (Bondo) to smooth out the surface. Apply the filler in thin layers, allowing each layer to dry before sanding.
- Sand the Body Filler: Once the body filler is dry, sand it smooth with various grits of sandpaper. Start with a coarser grit and gradually move to a finer grit.
- Prime the Surface: Apply a coat of primer to the entire area. Primer protects the metal from rust and provides a base for the paint.
- Sand the Primer: Lightly sand the primer after it dries to create a smooth surface for the paint.
- Paint the Rocker Panel: Apply several coats of paint, matching your truck’s color. Allow each coat to dry before applying the next.
- Clear Coat (Optional): Apply a clear coat for added protection and a glossy finish.
- Reassemble Components: Once the paint is dry, reassemble any components you removed earlier, such as door trim and mud flaps.
Step 6: Final Inspection
After the paint has fully cured, inspect your work. Make sure all welds are solid, the surface is smooth, and the paint matches your truck’s color. If everything looks good, you’ve successfully installed your new slip-on rocker panel!
