Why you'll love this Sierra 3500HD

This 2026 GMC Sierra 3500HD AT4 Crew Cab is equipped with a BDS Suspension 5" lift kit paired with FOX 2.5 Elite Series remote-reservoir shocks at both ends and completed with a four-wheel alignment, giving the truck a more purposeful stance while preserving the hardware needed for heavy-duty use. It rides on 22" Fittipaldi off-road FA27 wheels finished in full gloss black and 37x13.50R22 Nitto Ridge Grappler tires, and the exterior includes custom paint-matched fender flares along with professionally installed window tint covered by a lifetime warranty. Those additions are presented alongside the factory AT4 trim, so the truck keeps its original heavy-duty character while incorporating a number of visible changes that are easy to identify from the outside.

This Sierra 3500HD is built around GMC's heavy-duty platform and uses the Crew Cab body style for generous passenger space. The AT4 trim brings an off-road-oriented focus within the Sierra lineup, while the 3500HD designation places it in the brand's one-ton class for demanding towing and hauling duties. The suspension and wheel package gives the truck additional ground clearance and a more aggressive tire footprint than stock, while still keeping the overall presentation cohesive. The paint-matched flare treatment ties the wider bodywork into the rest of the exterior rather than leaving it looking like an add-on, and the tinted glass gives the cab a darker, more finished appearance without changing the truck's basic identity.

Inside, this GMC is equipped with leather seats, adding a more finished cabin treatment to the heavy-duty interior. The available navigation system is built into the truck's infotainment setup, and the premium audio system adds a more robust sound experience for everyday use or long drives. A Wi-Fi hotspot is also included, giving occupants another connectivity option when the truck is on the road or on-site. These features fit naturally with the Sierra's intended use, since the cabin is meant to serve as both a working space and a place where longer trips can be handled with fewer compromises.

Driver assistance and convenience equipment includes adaptive cruise control and collision warning, both of which add extra awareness in traffic and on extended highway runs. This 2026 GMC Sierra 3500HD AT4 Crew Cab combines that technology with the other listed equipment in a way that keeps the truck focused on utility rather than appearance alone. The added suspension travel, larger wheels, and 37" tires give it a custom-built look and a different road presence, but the underlying priorities remain the same: heavy-duty capability, a well-equipped interior, and an exterior finish that reflects the work already done to it.

⭐️⭐️⭐️⭐️⭐️ We just purchased a customized vintage-style 2024 Bronco Badlands, and couldn’t be happier with the experience. Our sales representative, Chris Fisher and Bill were fantastic—Chris kept us updated throughout the entire build and customization process. Even while we were out of the country for six weeks, Chris made sure everything stayed on track, making the whole experience smooth, easy, and stress-free. Highly recommend!

R. Agnetti

⭐️⭐️⭐️⭐️⭐️ So how was my experience? Well, I upgraded Broncos from a wild track to a raptor. I originally bought my wild track from Lifted Trucks and the first time I dealt with them. It was such a great experience that I chose to deal with them again if it hadn’t been for the experience that I got before and also recently with Jr and James not to mention Sam he was clutch in this arrangement to make this happen I appreciate Lifted Trucks for the time consistency and dedication. They put into making sure that not only did I get what I wanted, but I got it a deal better than I thought. Thank you guys. I will continue to be a loyal customer.

⭐️⭐️⭐️⭐️⭐️ Outstanding Experience at Lifted Trucks Phoenix! We recently purchased our new Raptor Bronco from Lifted Trucks Phoenix, and the experience was absolutely top-notch from start to finish. A huge thank-you to Manager Bill Murphrey and Sales Rep Grayson Neal for making everything smooth, honest, and enjoyable. Bill and Grayson went above and beyond to answer all our questions, keep us updated, and ensure we got exactly what we were looking for. Their professionalism, friendliness, and genuine passion for what they do really stood out. The whole process was quick, transparent, and completely stress-free. If you’re in the market for a lifted truck or performance vehicle, we highly recommend checking out Lifted Trucks Phoenix — and be sure to ask for Bill and Grayson. You won’t be disappointed!

C. Skyler

⭐️⭐️⭐️⭐️⭐️ I recently used Lifted Trucks to buy a used Ram Power Wagon and I was very pleased with the experience. Jacob was my salesman and he was very easy to work with and responsive. They gave me a good deal on both my trade in and my new truck that I was happy with. Both trucks were shipped and it was a completely hassle free experience. I’m definitely going to recommended them and use them in the future. I also love my new truck!

T. Jones

⭐️⭐️⭐️⭐️⭐️ I can honestly say that this dealer went out of their way in ways that no other dealer ever has for me. Not only did they put me in one The most awesome trucks they had on their lot.(24’ RAM 3500 Laramie) It’s by far the best truck I’ve ever owned. My credit wasn’t that great and they even held the truck for me for quite a while with a small Down payment On top of all that they accepted my trade-in, which was my work truck. I had put it through the ringer and they gave me more than double what any other dealer offered me. Lance the CEO and Adrian the manager Really stuck their neck outs for me and they didn’t have to. I live in San Diego And it was well worth the journey for the level of treatment that I received. Hats off These guys
