Nissan Frontier Running Boards: 2005-2027 Crew Cab Listings, King Cab Gaps and Sliders

Find your cab first. This comes from listing titles and the documents we name, read on November 2, 2026. How we verify fitment has the rule: we quote fit and we never work it out.

Fit sheetOur pick: Frontier Crew CabAd

Tyger Auto

Tyger Rider 3.5" (Frontier Crew Cab)

A 3.5-inch rail whose title names the Frontier years and cab, with a part number that leads to a readable sheet.

Why here: It names the truck, the years and the cab, and its part number leads to the one Frontier sheet we could read.

Why it makes the list

• The part number in the title (TG-SS2N35208) ties the listing to Tyger's instruction sheet
• That sheet uses 3 brackets per side on mounting studs and has no drilling step

Watch out for

• One range covers 2005-2027, and the sheet itself names no truck or year, so confirm your year on the listing
• 3.5 inches wide per the title, narrower than a 6-inch board
• No weight rating in the sheet, so none is printed here

Best for: Frontier Crew Cab owners who want a tube rail and a sheet they can read before they order.

What Tyger's sheet says

The sheet for TG-SS2N35208 is a plain bolt-on, and it reads like one:

• Brackets: 3 per side, at the front, center and rear mounting locations.
• Mounting: on the truck's mounting studs. Step 1 says to clean them with a wire brush first, to remove paint and debris. Each bracket takes 2 washers and 2 flange nuts.
• Drilling: no drilling step.
• Finish: do not slide or rotate the rail on the cradles, or you may damage the finish. Level it, tighten everything, then inspect the hardware periodically.

The sheet states no install time and no load rating, so we print neither. It also names no truck or year. The Frontier link comes from the part number in the title. That matters on a title spanning this many model years, so read the next part.

One range, 2005 to 2027: do not take it on faith

A single title covers more than two decades of one truck name. Nothing we read from Nissan speaks to whether the mounting points stayed the same, and we do not guess. Here is where the years disagree:

Tyger's site refused our direct requests, which is why the third line is an excerpt. Bottom line: on a 2026 or 2027 truck, run the fit check on the listing or ask the seller.

Crew Cab or King Cab: know yours before you order

ARIES lists Regular, King and Crew for the Frontier, with King in the extended group and Crew in the crew group. Nissan's own specs page shows a Crew Cab S, SV, PRO-X and PRO-4X, with a door count of 4 and rear doors described as "Conventional". Beds run 59.5 inches on three of those trims and 73.3 inches on the PRO-4X Long Bed. That page showed us no King Cab trim, so it does not settle the King Cab story for your year.

Count your doors, then look at how they open. How to tell which cab you have walks through it. None of the titles here names a bed length. If you are looking at anything that runs wheel to wheel, read bed and cab fitment first.

The other two Crew Cab options

The Tyger LanderX^* is the drop step, for when a tube rail still leaves too big a first step. It names a part number, but we could not read a sheet for it, so this is listing data only. Drop steps covers that style. The unbranded boards^* name no part number at all, so you are taking the seller's word on everything past the title. Check your exact year and cab on the listing before you buy.

Factory parts, side steps and sliders

Factory parts. People search for OEM boards on this truck, and we read no Nissan accessory page that lists them. One Nissan parts dealer shows separate numbers for 2022-2024 steps, T99T6-9BU30 for Crew Cab and T99T6-9BU40 for King Cab. That is a dealer's page, so use the numbers to start the conversation at the parts counter, not to settle it.

Side steps, nerf bars, step bars. All these words get searched for the same truck, and the Tyger title stacks three of them on one part: "Side Step Rail Nerf Bars". Words are not a build guarantee. Go by the shape and width in the title. Nerf bars explains the tube style.

Rock sliders. Not in our data for the Frontier. A step rail is not a slider, even if a listing says so. See rock sliders before you spend money expecting rock protection.

Shopping a Toyota too? Tacoma running boards has the same kind of cab trap. Every other truck is under all trucks, and how to check a listing fits works on any of them. Check your exact year and cab on the listing before you buy.
