Running Boards: See Side Steps on Your Own Truck or SUV

Running boards give you a wide step up into a tall truck or SUV. See flat black boards on a silver pickup and a black three-row SUV, then upload a photo of your vehicle and see how boards change the side profile before you buy a set.

Two vehicles, bare rockers to running boards

Each pair is one AI-drawn before photo and that photo after one Modification Goals request, sent through the same image model, step count and request wording that Custom Vision uses. Each after-image is a single run, and where we reran a request the caption says so. The full request text sits under each pair.

AI-drawn sample: a plain silver full-size four-door pickup with silver wheels and nothing under the doors, seen from the side in a driveway — Modification Goals: "add wide flat black running boards under the doors along both cabin doors, with a ribbed rubber tread strip on top; keep the same truck, paint, wheels and background". Followed: a flat black board with a ribbed top now runs under both cab doors, and the silver paint, wheels, windows and driveway look the same. Differences to know about: none that we could see. Extra changes: none that we could see.

AI-drawn sample: a plain black full-size three-row SUV with black wheels and nothing under the doors, seen from the side on a street — Modification Goals: "add wide flat black running boards under the doors running the full length between the front and rear wheels, with a ribbed rubber tread strip on top; keep the same SUV, paint, wheels and background". Followed: a flat black board with a ribbed top now runs between the front and rear wheels, and the black paint, black wheels and street look the same. Differences to know about: on a black body the black board is hard to pick out at small sizes; try a silver or chrome board if you want it to stand out. Extra changes: none that we could see.

What running boards are

Running boards are wide, flat steps that mount below the doors of a truck or SUV and run most of the way between the wheels. They give the largest step of the side-step options. Nerf bars are narrower round or oval tubes with step pads at each door, and power steps are motorized boards that fold away under the body and drop down when a door opens. Most boards bolt to the rocker or the frame with brackets made for one model.

Side step styles people pick

Flat black board

A wide step with a rubber tread, like both of our examples.

Aluminum or chrome board

A bright finish that stands out on dark paint.

Oval tube step

A narrower tube with step pads, often called a nerf bar.

Power step

A board that hides under the body until a door opens.

Cab length or full length

Boards under the cab doors only, or the whole way between the wheels.

How to preview running boards

1
Take a clear photo
A straight side view shows the doors and the gap from the rocker to the ground.
2
Open the Modifications tool
Upload the photo and switch to Custom Vision.
3
Describe the change
Say flat running boards, oval steps or power steps, the color, and how long they run.
4
Say what stays
Say the paint, wheels and body stay the same, and rerun if the board looks too thin to see.

Two Modification Goals to paste

We used these requests for the examples. Copy one into Modification Goals and change the part words for your own vehicle. Swap black for chrome, or flat boards for oval steps, to compare.

What the AI does well and where it slips

The model adds boards under the doors and keeps the paint, the wheels and the scene. Black boards on a black body can be hard to see, and it cannot show a power step folding in and out. Use the render to judge the look and the length, then buy boards made for your cab size and model.

Frequently asked questions

Running boards or nerf bars: what is the difference?

Running boards are wide and flat, with the most room for your foot. Nerf bars are narrower tubes with step pads at each door, and usually cost less.

Are power running boards worth it?

They tuck away for a clean look and drop down when you open a door, but they cost more and have a motor that can fail. Fixed boards have no moving parts.

Do running boards hurt off-road clearance?

They can hang below the rocker and catch on rocks. Off-road trucks often use frame-mounted steps instead.

Will running boards fit my truck?

Most kits are made for one model and cab size, and bolt to the rocker or frame. Check the fit list for your exact truck.

Can I see black and chrome boards on my truck?

Yes. Run one request for each color on the same photo and compare them.

Can I preview running boards on my own car for free?

Yes. Sign in with email or Google, upload a photo of your car in the Modifications tool and paste a goal like the ones below into Modification Goals in Custom Vision. Most new accounts get 5 free credits that last 30 days, and a standard render uses 1 credit. Free renders carry a WheelAI watermark.
