The Hidden Problem: Not All Running Boards Are Created Equal

While running boards might appear similar at first glance, the underlying differences between OEM and aftermarket options can have long-term consequences. Many vehicle owners assume aftermarket boards will perform just as well as factory parts, but this isn’t always the case. Differences in materials, structural design, corrosion resistance, and safety certification can affect not only the performance and lifespan of your running boards but also your vehicle’s integrity and resale value.

Why the Distinction Matters: Safety, Performance, and Compliance

Running boards are more than a cosmetic accessory—they provide a stable stepping surface, protect your vehicle’s lower body, and can even improve aerodynamics when properly designed. However, substandard materials or poor fitment can lead to premature corrosion, compromised safety, or even frame damage. According to the National Highway Traffic Safety Administration, vehicle equipment—including running boards—must meet specific safety and performance criteria to ensure occupant protection and reduce injury risk.

Materials and Construction: The Foundation of Quality

OEM Running Boards: Engineered for the Vehicle

OEM running boards are designed and tested in conjunction with the vehicle’s engineering team. They are typically constructed from high-strength materials such as aluminum alloys, reinforced plastics, or corrosion-resistant steel. These materials are chosen to match the vehicle’s load-bearing requirements and to withstand environmental stresses like road salt, moisture, and UV exposure. The U.S. Department of Energy highlights the importance of advanced materials in automotive body structures for optimizing weight, strength, and corrosion resistance.

Aftermarket Running Boards: Wide Range of Material Choices

Aftermarket running boards vary widely in material quality. While many reputable brands use high-grade aluminum or stainless steel, others may opt for lower-cost mild steel or plastic composites. Material thickness, weld quality, and protective coatings also fluctuate. Some aftermarket boards rival OEM quality, but others may be more susceptible to rust, bending, or finish degradation—especially in harsh climates.

Material Checklist for Running Boards

• Aluminum Alloy: Lightweight, corrosion-resistant, strong. Preferred for most OEM and high-end aftermarket boards.
• Stainless Steel: Durable, excellent corrosion resistance, heavier than aluminum.
• Mild Steel: Strong but prone to rust if not properly coated.
• ABS or Polypropylene Plastics: Lightweight, can be reinforced, but may crack or fade over time.
• Powder-Coated Finishes: Essential for steel boards to prevent corrosion.
• UV-Resistant Coatings: Prevents paint or plastic from fading.

Fitment and Compatibility: The Key to Longevity and Safety

OEM Fitment: Precision and Seamless Integration

OEM running boards are engineered for a perfect fit with your specific vehicle make, model, and year. This ensures not just aesthetics, but also proper load distribution and secure mounting points. OEM boards align with factory holes and brackets, eliminating the need for drilling or modifications. This precision fitment reduces stress on the vehicle’s frame and body, minimizing the risk of rattling, loosening, or accidental detachment.

Aftermarket Fitment: Universal vs. Custom

Aftermarket running boards come in two main styles: universal and vehicle-specific. Universal boards are designed to fit a wide range of vehicles, which can lead to compromises in mounting security and appearance. Even vehicle-specific aftermarket boards may require additional brackets, spacers, or drilling, depending on the manufacturer. Incorrect fitment can lead to water ingress, corrosion, or structural stress.

Installation Checklist

• OEM Running Boards:

  • Aligns with factory mounting points
  • No drilling or modification required
  • Includes all necessary hardware
  • Installation time: 30–60 minutes

• Aftermarket Running Boards:

  • Check for vehicle-specific fitment
  • Confirm if drilling or bracket adaptation is needed
  • Inspect included hardware for quality
  • Installation time: 1–2 hours (may vary)

Durability and Corrosion Resistance

OEM: Tested for Longevity

OEM running boards undergo rigorous corrosion, weather, and load testing as part of the vehicle’s overall durability program. They are engineered to last the lifespan of the vehicle, with finishes and materials that resist chipping, rusting, and fading. OEMs use advanced coatings and sealants to protect against deicing salts, road debris, and UV radiation.

Aftermarket: Variable Durability

The durability of aftermarket running boards varies dramatically by brand and price point. High-quality aftermarket products may use similar materials and coatings as OEM, but budget options might cut corners. Lower-cost boards are especially prone to surface rust, paint chipping, or plastic degradation—issues that can compromise safety and appearance over time.

Maintenance Considerations

• Regularly inspect running boards for chips, scratches, or rust.
• Clean boards with mild soap and water; avoid harsh chemicals that strip coatings.
• Apply protective wax or sealant to maintain finish.
• Touch up paint or coatings promptly if damaged.
• Check mounting hardware for corrosion or loosening.

OEM: Built to Regulatory Standards

OEM running boards are required to meet stringent safety and performance standards set by organizations such as the National Highway Traffic Safety Administration (NHTSA) and SAE International. These standards cover load-bearing capacity, slip resistance, and crash performance. OEM parts are also subject to recall procedures if defects are discovered, ensuring accountability and consumer protection (NHTSA Equipment).

Aftermarket: Certification Is Not Guaranteed

Not all aftermarket running boards are tested to the same standards as OEM parts. Some reputable manufacturers do certify their products to SAE or equivalent standards, but others may not. Lack of certification can pose safety risks, especially if the board fails under load or detaches in an accident.

Safety Checklist

• Look for SAE or NHTSA certification on packaging or manufacturer’s website.
• Verify load ratings match or exceed OEM specifications.
• Choose boards with non-slip surfaces for added safety.
• Ensure hardware is grade-rated and corrosion-resistant.
