2013-2023 Rolls-Royce Wraith & Dawn Rocker Panel Molding: Damage, Cost, and Replacement
A detailed guide to inspecting, pricing, and replacing the rocker panel moldings on the Rolls-Royce Wraith and Dawn.
- This part fails from physical damage, not defects. Check for cracks from curbs or improper jacking.
- When buying used, the most critical inspection is for intact mounting tabs on the back of the panel.
- A new OEM molding can cost over $2,100, making a quality used OEM part a significant value.
- Replacement is a body shop job due to the risk of paint damage and the need for precise alignment.
Symptoms of a Damaged Rocker Panel Molding
Failure of the rocker panel molding is almost always due to physical damage rather than a manufacturing defect. Because of its low position on the vehicle, it is highly susceptible to impacts. There are no specific fault codes or electronic warnings associated with this part.
- Visible Cracks, Scuffs, or Gouges: The most common symptom is cosmetic damage from curb strikes, steep driveways, or large road debris. Deep scratches or cracks can compromise the panel's finish and appearance.
- Loose or Rattling Panel: The molding is attached with a series of clips and fasteners. An impact can break these mounting points, causing the panel to become loose. You may hear rattling or vibrating noises, especially at higher speeds. A loose panel can also create a visible gap between the molding and the car's body.
- Damage from Improper Jacking: Placing a floor jack directly on the rocker panel molding instead of the designated chassis lift points will cause it to crack or shatter. This is a common source of damage during service or tire changes if proper care is not taken.
Warning: A severely damaged or loose rocker panel molding can detach from the vehicle while driving, creating a serious road hazard for other motorists. It should be repaired or replaced promptly.
Known Issues, TSBs, and Recalls
As of this writing, there are no specific recalls or Technical Service Bulletins (TSBs) issued by Rolls-Royce or the National Highway Traffic Safety Administration (NHTSA) for issues related to the rocker panel moldings on the 2016-2023 Dawn or 2013-2023 Wraith. Problems with this part are typically addressed on a case-by-case basis as cosmetic or physical damage repairs.
Buying a Used Rocker Panel Molding: What to Check
Given the extremely high cost of a new OEM rocker panel, a recycled OEM part is an excellent value. These vehicles are produced in low numbers, so used parts are not plentiful but can be found. Since the Wraith and Dawn share a platform, their rocker moldings are often interchangeable, but always verify the part number before purchasing.
Inspection Checklist:
- Check for Cracks: Carefully inspect the entire surface, especially the front and rear ends and the bottom edge, for any cracks. Even a small crack can spread over time. Pay close attention to the areas around mounting holes.
- Look for Previous Repairs: Examine the backside of the panel for signs of plastic welding, epoxy, or body filler (Bondo). A wavy finish or inconsistent texture can indicate a past repair that may not last.
- Verify All Mounting Tabs: This is the most critical inspection point. The panel attaches to the car with a series of plastic clips and tabs. Turn the panel over and ensure every single mounting tab and clip holder is intact and free of stress marks or cracks. A single broken tab can cause a section of the panel to be loose or misaligned.
- Assess the Finish: Used moldings will almost always need to be repainted to match your vehicle. However, look for deep gouges or scrapes that would require significant filler to smooth out. A part described as "restored from minor scuff" is common and often a good option if prepared professionally.
- Confirm Part Number: The part number for the Wraith is often cited as 51777301424, and for the Dawn, 51777371324. Some sources indicate they are the same part. Cross-reference the number from your existing panel if possible to ensure a perfect fit.
Pro Tip: Ask the seller for high-resolution photos of the back of the panel. This is the best way to verify that all mounting points are intact before you buy.
Replacement Cost and Difficulty
Replacing a rocker panel molding on a Rolls-Royce Dawn or Wraith is a job best left to a professional body shop. The risk of damaging the expensive panel or the vehicle's paint is high without the proper tools and experience.
Installation Difficulty: 3/5 (Moderate - requires care and precision)
The process generally involves:
- Removing fasteners inside the front and rear wheel wells.
- Removing any scuff plates or lower trim pieces that overlap the molding.
- Carefully prying the panel away from the body to release the series of retaining clips. This is the most delicate step, requiring plastic trim removal tools to avoid scratching the paint.
- Cleaning the mounting surfaces on the vehicle body.
- Aligning and installing the new panel, ensuring every clip snaps securely into place.
- Re-installing all screws and other trim pieces.
Cost Comparison
Aftermarket options for this part are not available. The choice is between a new factory part or a used OEM part. Prices can vary based on condition and availability.
| Part Type | Estimated Cost |
|---|---|
| New OEM | $2,100 - $2,500 |
| Used OEM | $850 - $1,200 |
| Shop Labor (Body Shop) | $300 - $600 |
Labor costs are estimated based on a rate of $150-$200/hour for 2-3 hours of work, which is typical for a high-end European vehicle body shop. This does not include the cost of painting the panel, which can add several hundred dollars.
Frequently Asked Questions (FAQ)
Can I replace just one side?
Yes, rocker panel moldings are sold individually for the left (driver's) and right (passenger's) side. You only need to replace the damaged side.
Does the used part come painted?
A used part will come in its original color. It is highly unlikely to be a perfect match for your vehicle due to differences in paint codes and fading. You should always plan to have a used body panel professionally prepped and painted to match your car's exact paint code.
Are the mounting clips reusable?
It is possible but not recommended. The plastic clips can become brittle with age and may break during removal of the old panel. It is best practice to install a new panel with a fresh set of retaining clips to ensure a secure, rattle-free fit. Your body shop can source these for you.
Is this the same part as the structural rocker panel?
No. This part is a decorative and protective plastic or composite molding (or side skirt) that covers the actual rocker panel. The structural rocker panel is a welded part of the car's unibody frame and is much more difficult and expensive to repair. Damage to this molding usually does not mean there is structural damage to the car.
