Running Boards for Extended, Double, Quad and SuperCab Trucks

Here is the problem with "extended cab". It describes a group of cabs, and many makers do not put that word on the truck. According to the ARIES cab guide, an extended cab has at least two full-size, front-hinged doors and seating behind the first row, reached by moving the front seats forward or through smaller rear doors. Each maker gives that cab a name of its own, and sellers title their parts with that name.

So first get the name right. Then buy the part. If you are not sure which cab you have, how to tell which cab you have takes a few minutes. The full cab guide explains the whole family, and extended cab vs crew cab covers the difference in detail.

What your maker calls an extended cab

ARIES says its table only aids understanding and does not imply shared designs. Fit in every section below is what the title states, read 2 November 2026. See how to check a listing fits for the last step.

Where to start

We have no "our pick" on this page, and that is deliberate. We award that label only where we read a maker sheet, and none of these listings has one we could read. So treat the choices below as a place to start, by truck.

COMNOVA

COMNOVA 6" Double Cab (2007-2018 GM)

Why here: Its title uses both cab names, Double and Extended, in one line, which answers the question most GM owners have.

Why it makes the list

• Title names both cab terms, which helps when your paperwork says the other one
• Title names stainless steel

Watch out for

• Listing data only
• No weight rating in the title, so none is printed here
• Stainless grade is not stated

Best for: Owners of a 2007-2018 GM truck with the shorter rear doors.

Listing data only: We only have the Amazon listing title for this one, no maker sheet. It is an option, not a recommendation.

View on Amazon*(paid link to Amazon, opens in a new tab)Ad · paid link · check price & delivery on AmazonLearn more

The title reads "Double Cab" up front and then "2007-2018 Chevy Silverado/GMC Sierra 1500 Extended Cab, 2007-2019 Silverado/Sierra 2500HD 3500HD". That helps when your paperwork says one word and the listing says the other. It names stainless steel with no grade and states no weight rating. Price class: budget. Our Silverado page has the rest of that truck.

Strength: the clearest cab wording in this group. Weakness: title data only.

MaxMate 3-inch for older GM Double Cabs

The MaxMate^* is a 3-inch tube titled for 1999-2018 Silverado and Sierra 1500 and 2500 LD, 2001-2019 2500 and 3500HD, and the 2019 LD/Limited, excluding the SS, with Double Cab named. It takes up the 2019 LD question, which most titles skip.

Strength: wide year coverage as stated. Weakness: at 3 inches, it is the narrowest step in our data, and it is listing data only.

Aluminum Quad Cab for the older Ram body and Classic

This aluminum step^* is one of the few titles in our data to name the Quad Cab. It says "Quad Cab", then 2009-2018 Dodge Ram 1500, Ram 2019-2024 1500 Classic and Ram 2010-2026 2500 3500, and "New Body Style Not Fit". Price class: budget. There is no brand in the title.

One thing to look at twice: the title lists the 2500 and 3500, while the ARIES table shows no extended-group cab for those trucks. We quote the title and do not explain the gap. If you drive a 2500 or 3500, confirm with the seller. The Ram 1500 page goes through the Classic split.

Strength: it names the cab and rules out the new body. Weakness: no brand, no sheet, and no new-body option.

Tacoma Access Cab and XtraCab

Most Tacoma parts we read say Double Cab, and that is a crew-group cab per ARIES, so those do not help here. Two listings do name the smaller cab.

The first^* is titled for the "2005-2023 Toyota Tacoma Xtar/Access Cab", spelling and all. It names no brand. The second^* is the Tyger Trax titled for the "2024-2027 Toyota Tacoma", XtraCab, with part number TG-TX7T28228 and a mid-range price class. We could not read Tyger's sheet for it. The Tacoma page covers the generation split.

Strength: they name a cab that many lists skip. Weakness: listing data only, both.

Tundra Double Cab

This listing^* is titled for the 2007-2021 Toyota Tundra Double Cab. ARIES files that cab under extended. It is listing data only, and the Tundra page has the CrewMax split, which is a different cab and a different part.

Colorado Extended Cab and Super Duty Super Cab

The first is titled for the "2015-2026 Chevy Colorado/GMC Canyon Extended Cab", with no brand. The second is COMNOVA's title for the "1999-2016 Ford F250 F350 Super Cab". Both are listing data only. Check your exact year and cab on the listing before you buy.

Other cabs, and where to look

F-150 SuperCab. We have no Amazon listing for it in our data. Ford's own catalog does name it, for example "F-150 SuperCab 2015-2027 5 in. Aluminum Step Bars in Black" and "F-150 SuperCab 2021-2027 Extended Length Step Bars". Westin's Pro-e fit table also names SuperCab trucks. See the F-150 page for details.

Colorado, Canyon and Super Duty. We saw Amazon titles naming the Colorado and Canyon Extended Cab and the 1999-2016 F-250 and F-350 Super Cab, but they are not in our product list yet, so we cannot show you a checked fit line for them.

New-body Ram 1500 Quad Cab. No Amazon listing in our data. That does not mean none exists.

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

What to check before you order

• The cab name. It must match what your maker calls your cab. "Extended" alone in a title is not enough, because the name changes by truck.
• Your rear doors. Short doors, or none and a seat that moves forward, point to the extended group. Doors that may open only after the front doors are open are an extended-cab trait, per ARIES. That also matters for where a step sits.
• Length. RealTruck's guide for the AMP PowerStep 76255-01A uses 79 inches for a Crew Cab and trims it to 69 for a Double Cab. That number is for that part only, but it shows why length follows the cab. Bed and cab fitment has more.
• Drilling and load. None of these titles states a weight rating, so we print none. Ask the seller for an install sheet before you assume no drilling.

Mistakes that cost you a return

• Ordering a crew cab part because it has more choice. Most of the market is crew cab. That does not make it yours.
• Carrying Double Cab across makers. A Silverado Double and a Tacoma Double are in different ARIES groups.
• Going by door count. Four door handles do not make a crew cab. See what is a crew cab.
• Treating a missing name as a yes. If your cab is not in the title, ask the seller. Do not assume it.

Bottom line

Name your cab first. On a 2007-2018 GM, start with the COMNOVA 6-inch^*. On an older Ram Quad Cab or Classic, start with the aluminum Quad Cab step^*. If your cab is not named on any of these, do not settle for the closest thing. Everything here follows how we verify fitment, so nothing above comes from an install of our own. Check your exact year and cab on the listing before you buy.
