How Much Weight Can Running Boards Hold? Maker Ratings, Per-Side vs Total, and What Is Unrated

The common answer, a range of a few hundred pounds per side, is not something you can use. It mixes makers, bases and sources that do not line up. So we took the opposite approach: a number goes on this page only if the maker's own page or sheet states it, and we read that document ourselves on November 2, 2026.

What makers state

Do not stack these up as a ranking. They are different products, and the makers do not say they measured them the same way.

How to read a rating

Per side or total. A per-side number and a pair number are not the same claim. A bare figure could be either, so make the maker say which.

Static. ARIES uses that word. Static means a load that is not moving. Coming down hard on a step with a boot is not that, and no document here gives a dynamic number.

Limited by what. ARIES adds "limited to mounting structure". That is the most honest phrase on this list. A step is bolted to your truck, so the rating is only one part of the story, and rust or damage where it mounts is your problem to check. Heavy-duty running boards goes further into what mounts tell you and what they do not.

One part, not the brand. OEDRO's number sits on one Tacoma page, and other OEDRO pages state none. Westin's other lines state none on the pages we read. WOLFBOX's figure sits on its Chevy/GMC and Ram pages, and we could not open its Ford page. Do not carry a figure from one part to another.

Where the numbers we refuse to print come from

You will see plenty of figures that are not on this page. Here is why.

• Listing titles. A seller can put anything in a title. The WOLFBOX F-150^* and VEVOR^* titles each carry a load figure. Those are title claims. WOLFBOX's page for the Ford part would not open for us, so its Chevy/GMC and Ram figure does not carry over. Check your exact year and cab on the listing before you buy.
• Dealer pages. Rough Country, Go Rhino and Carr figures reached us only through dealers, and some of them disagree. N-Fab's figure did too: we saw it on retailer listings, and n-fab.com now redirects to RealTruck.
• Bully. BullyUSA.com prints a load and an install time, but its footer calls it an independent enthusiast website. That is not a maker document, so neither is here.
• AMP PowerStep and XL. Figures differ between pages, and the guides we read print none. The PowerStep XL page lays that out.
• AI answers. One told us the Pro-e holds twice what Westin states.

How we verify fitment has the full rule.

Is there a government number?

Only for other trucks. 49 CFR 399.207 says each step must withstand a vertical static load of at least 450 pounds, but its scope is high-profile cab-over trucks and truck-tractors. We found no equivalent for pickups. So do not read that figure as a rule for your F-150, and do not treat any step as certified to it.

What to do

Fit sheetOur pick: Silverado and Sierra crewAd

Tyger Auto

Tyger Rider 3.5" (2019+ GM)

A 3.5-inch rail whose title names the Silverado and Sierra years, the HD split and the cab.

Why here: This is an example of the common case, not a load pick: its sheet tells you the brackets and mounting points, and it states no rating. So nothing here is rated, and you should ask Tyger if the number matters to you.

Fits, according to the listing

2019-2026 Chevy Silverado GMC Sierra 1500; 2020-2027 2500 3500HD | Crew Cab (as of November 2, 2026)

Style

Rail / nerf bar (as titled)

Material

Not stated in the title

Weight rating

Not stated in the title

Install

Bolt-on with 8 brackets; no drilling step in the sheet; assistance recommended

Price class

Mid-range

Check your exact year and cab on the listing before you buy.

Why it makes the list

• The part number in the title (TG-SS2C35068) ties the listing to Tyger's own instruction sheet
• That sheet bolts 8 brackets to threaded holes behind plugs in the rocker area and has no drilling step
• Title separates the 1500 years from the 2500/3500HD years

Watch out for

• 3.5 inches wide per the title, narrower than the 6-inch boards
• No weight rating in the title, so none is printed here
• The title does not mention the 2019 LD/Limited; a sister Tyger listing groups that truck with the older body, so check before ordering

Best for: Crew cab owners on the 2019-up GM full-size who want a rail with a readable install sheet.

If a rated number is what you are shopping for, the short list is the parts in the table, and you still have to match the part to your truck. If it is not, pick on fit and install, and keep the part bolted tight. Rock sliders are a separate claim again, as rock sliders vs running boards explains. Powered options are on power running boards, and the home page has the fit finder for your truck.
