2025 GMC Sierra AT4 Harley Davidson Edition: Full Walkaround and Feature Breakdown

If you’ve ever wondered what would happen if Harley Davidson’s iconic design met the rugged capability of a GMC Sierra, the all-new 2025 GMC Sierra AT4 Harley Davidson Edition is the answer. In a detailed walkaround, Brian from GMC takes us through what makes this collaboration an absolute head-turner, and trust us—it’s more than just some badging.

Bold Harley Davidson Styling, Inside and Out
Right from the start, the truck stands out with unique air vents along the sides, each sporting a functional design and Harley Davidson shield logos. There’s rocker protection that doubles as a home for retractable running boards. Unlike typical setups, this truck cleverly blends both features for added utility and flair.

A true homage to Harley’s motorcycle heritage, the wheels are inspired by the Fat Boy design, giving the Sierra a look you won’t find anywhere else. Thanks to an exclusive lift by Fox, the ride is not just higher but also remarkably smooth—a nice surprise for a truck this aggressive.

The iconic Harley Davidson aesthetic carries right through to the front: the grille features the Harley shield, surrounded by distinctive orange accents, and even the tow hooks have been color-matched in orange for a cohesive look. Check out the hood—it sports a functional air scoop with a cowl-inspired raised section, adding to that muscle-car vibe.

Custom Touches All Around
Branding is everywhere but tastefully done. The front windshield rocks a Harley Davidson logo, there’s “Harley Davidson” stamped just below the grille, and body-colored fender flares tie everything together. At the rear, you’ll spot dual brushed black exhaust tips with orange trim and a custom rear bumper designed to accommodate the new exhaust style.

The enhancements continue with a fiberglass tonneau cover featuring a stamped Harley shield. Open it up and you’re greeted by a carpeted bed liner—complete with a Harley logo—that can be removed to reveal a spray-in liner underneath. GMC’s MultiPro tailgate is standard, adding to the truck’s versatility.

Interior: Comfort Meets Harley-Inspired Cool
Step inside, and you’ll find orange accent stitching throughout, a nod to Harley Davidson’s signature palette. The quilted, perforated leather seats feel upscale, offering heated rear seating and easy-clean all-weather floor mats. Open the front doors and you’re greeted with Harley Davidson kick plates, and the front seats feature embroidered logos on the seatbacks.

Look closer and you’ll see a Harley shield with wings on the center console, and a plaque marking the truck’s unique serial number—this is a true limited edition (number 24 out of a select production run). Finishing touches include orange-stitched dash trim and a matching steering wheel, all culminating in an interior that’s just as special as the exterior.

Who’s It For?
Whether you’re a Harley Davidson enthusiast wanting a four-wheeled tribute, or someone who loves unique, bold trucks with premium features, the 2025 GMC Sierra AT4 Harley Davidson Edition delivers style and performance in equal measure.
