Is there a weight limit on running boards?
Yes. There is typically a weight limit for running boards, and it varies by model and installation. Most consumer-grade running boards are rated for hundreds of pounds per board, but you should check the exact specification for your setup.
Running boards are rated for static weight (the weight you place on the board while standing) and sometimes dynamic loads (during entry, exit, or movement). The rating can refer to a single board or the entire assembly, and OEM-installed boards often have different ratings than aftermarket units. This article explains how weight limits are defined and how to verify them for your vehicle.
What determines a running board's weight rating
Before listing how to check, here's what you need to know about the numbers you will see:
- Static load rating: the maximum weight the board can support per the manufacturer's test under stationary conditions.
- Dynamic load rating: the expected weight during entry/exit and movement, which is often lower than the static rating.
- Per-board vs per-assembly: some products rate per individual board; others rate the entire running board system, including mounting hardware.
- OEM vs aftermarket: OEM boards may have different mounting points and ratings; installation quality matters.
- Material and construction: aluminum vs steel, tube design, cross-members affect strength and weight rating.
Ratings vary; always verify the rating applies to your particular model and installation. If in doubt, consult the manufacturer or dealer.
How to find the weight rating for your running boards
To determine the exact weight limit for your setup, check the following sources and steps:
- Product page or packaging: look for "static load" or "weight capacity" and the value, with units in pounds (lbs) or kilograms (kg).
- Owner's manual or installation guide: the manual often lists load ratings and mounting requirements.
- OEM boards: look for a label in the owner's manual or on the board itself; sometimes the rating is in the door jamb sticker or vehicle brochure.
- Aftermarket boards: check the manufacturer's website for the model's weight rating and whether it is per board or for the whole system.
- Model number and serial number: will help you search for the exact spec if packaging is missing.
- Contacting customer support or a dealer: if you're unsure, they can confirm the exact rating for your configuration.
Knowing the exact rating helps you plan safe use and ensures you don’t overburden the boards during entry or while loading cargo.
What to do if you need a higher weight rating
If your usage requires heavier loads than your current running boards are rated for, consider these options:
- Upgrade to heavy‑duty or OEM boards designed to support higher weights (often 600–1000+ lbs per board in some applications).
- Ensure proper installation with the correct hardware and torque specifications; improper mounting can reduce capacity.
- Check mounting points; some vehicles require reinforcement or different mounting brackets for higher-capacity boards.
- Avoid dynamic loading; use handholds and maintain three points of contact when entering or exiting.
- Inspect boards regularly for damage, corrosion, or loose hardware; replace if structural integrity is compromised.
If you routinely carry heavy loads or operate in rugged conditions, investing in boards with higher rated load and professional installation is prudent, and always follow the manufacturer’s guidance.
Safety reminders
Key cautions
Running boards are primarily for stepping assistance. Do not ride on them or stand with both feet while the vehicle is moving, and avoid mounting or dismounting while the vehicle is in motion. Always check for damage after off-road use and re-torque fasteners per the installation manual.
Summary
Weight limits for running boards exist and vary by model. Always verify the exact rating for your board (static vs dynamic, per-board vs per-assembly, OEM vs aftermarket) and ensure proper installation. If in doubt, contact the manufacturer or a certified installer. With the right board and proper mounting, you can safely use running boards to aid entry and cargo management without exceeding the rating.
