Running boards on an SUV are narrow steps mounted along the lower edge of the vehicle’s doors. They provide a sturdy lift point to help passengers enter and exit more easily, especially on taller models. Beyond aiding accessibility, running boards can protect rocker panels from debris and add a stylistic element. This article explains what running boards are, the different types available, materials used, benefits and drawbacks, maintenance tips, and how to choose and install the right set.
What They Are
Running boards are horizontal platforms attached beneath the doors of an SUV. They typically run the length of the front and rear doors, offering a step to reduce the climb into a higher cabin. Some designs also double as protection against rocks, mud, and minor impacts by forming a barrier at the vehicle’s sides. Modern running boards come in various styles, including full-length boards and narrower, step-friendly designs. They may be fixed, retractable, or hinged to retract under the vehicle when not in use, depending on the model and intended use.
Types Of Running Boards
Understanding the different types helps match a running board to driving needs and aesthetics.
- Simplest Fixed Running Boards: A permanent, low-profile board that runs under the doors for easy stepping. They are durable and often the most affordable.
- Full-Length Running Boards: Span both front and rear doors, creating a continuous stepping surface along the vehicle’s length. Ideal for tall SUVs and families.
- Nerf Bars: Tubular side bars that are primarily for protection and style, with a smaller stepping surface. They’re lighter and easier to install but offer less step area than full boards.
- Retractable Running Boards: Automatically deploy when doors are opened and retract when the doors close or at certain speeds. They provide a clean look and improved ground clearance when not in use.
- Corner Or Vented Designs: Some models feature cutouts or vented sections to reduce weight and wind resistance while maintaining step comfort.
Materials And Durability
Durability and weight capacity depend on material choice.
- Aluminum: Lightweight, corrosion-resistant, and common in mid-range models. Aluminum running boards balance strength and weight well.
- Stainless Steel: Extremely durable and resistant to corrosion, but heavier. Often used on rugged, off-road-oriented SUVs.
- Steel With Protective Coatings: Very strong and cost-effective; coatings protect against rust but can add weight.
- Fiberglass Or Composite: Lightweight and can offer unique shapes. Generally less durable than metal options but suitable for lighter-use vehicles.
Weight capacity varies by model and installation, commonly ranging from 250 to 600 pounds per running board. Check the manufacturer’s specifications for your vehicle and running board combination to ensure safe use with occupants and cargo.
Benefits And Drawbacks
Running boards offer several practical and cosmetic advantages, but they also have potential downsides.
| Benefits | Drawbacks |
|---|---|
| Improved access for all passengers, especially children and shorter drivers | Added vehicle width can affect parking and garage alignment |
| Rocker panel protection against rocks, mud, and debris | Potential for clogging with mud or snow in harsh climates |
| Aesthetics and potential resale value depending on style | Can increase undercarriage exposure to debris when off-roading |
| Can aid in loading roof accessories by providing a step up | Retractable designs require maintenance to ensure smooth operation |
Maintenance And Safety
Proper care extends the life of running boards and preserves safety.
- Regular Cleaning: Wash to remove mud, salt, and road grime that can corrode mounting brackets. Dry thoroughly to prevent rust.
- Inspection: Periodically check mounting bolts, brackets, and brackets for wear or looseness. Tighten as recommended by the manufacturer.
- Grip And Traction: Ensure stepping surfaces have adequate tread or grip to prevent slips, especially in wet or icy conditions.
- Compatibility Checks: Verify that doors and steps do not interfere with door seals, rocker panels, or vehicle liftgate when opened.
- Weather And Climate Considerations: In snowy regions, ensure snow does not accumulate on the boards and hamper stepping.
Installation And Fitment
Installation methods vary by design and vehicle. Fixed boards typically require mounting brackets that bolt to factory holes or reinforced chassis points. Retractable boards involve electrical wiring to sensors and power sources. Professional installation is often advisable for complex systems, especially on newer or high-end SUVs, to ensure proper alignment and weight distribution. When shopping, verify:
- Vehicle Specific Fit: Choose running boards that match your SUV’s make, model, and year for proper mounting points and clearance.
- Hardware Availability: Ensure that mounting brackets, screws, and instructions are included or readily available.
- Warranty And Support: Check if the manufacturer offers coverage on mounting hardware and finish quality.
Choosing The Right Set For Your SUV
The best running boards depend on usage, vehicle type, climate, and budget. Consider these factors when choosing:
- Access Needs: If frequent passengers include children or elderly riders, full-length and wider stepping boards may be beneficial.
- Climate And Terrain: In muddy or snowy environments, look for boards with good tread and easy cleaning, or choose retractable models to reduce exposure.
- Vehicle Style And Aesthetics: Choose a design that complements the SUV’s lines—sleek aluminum for modern looks or rugged stainless steel for off-road aesthetics.
- Weight And Handling: Heavier boards may affect fuel economy slightly and vehicle dynamics; assess the impact against benefits.
- Maintenance Willingness: Fixed boards require less upkeep than retractable systems but still need cleaning and periodic checks.
Practical Tips For Buyers
To maximize satisfaction, buyers should:
- Check Measurements: Measure door-to-ground distance on your SUV to ensure comfortable stepping height.
- Review Installation Guides: Read the installation manual or professional notes to understand required tools and torque specs.
- Evaluate Integrated Features: Some boards include lighting, integrated steps, or anti-skid surfaces for added safety.
- Think About Resale: Quality finishes and color-matched hardware can influence resale value more than price alone.
