The GMC Sierra 3500 is known primarily for one thing: getting work done.

These are some of the most undisputed, toughest, nastiest, and most able trucks ever built. But just because they’re technically work trucks doesn’t mean they’re the boxy old featureless behemoths of yesteryear.

And with every level coming with a bevy of options and add-ons, no two Sierra 3500 trucks are quite the same.

All Sierra 3500 models come packed with a rough-and-tumble 6.6-liter V8 gas or 6.6-liter turbo diesel powerplant that can put down upwards of 464 pound-feet of torque and is mated to either a six- or ten-speed automatic transmission. And with rear- or four-wheel-drive options, and a variety of cab sizes and bed lengths, the perfect truck for you and your needs is out there.

Let’s explore the trim levels of the new Sierra 3500 so you can pick the truck for you.

The Base Model

The low-frills, low-cost model is still plenty capable of getting just about anything done, no matter the mission or the environment thanks to that legendary GMC motor.

It also sports a heavy-duty locking rear differential and a seven-inch infotainment system feature Apple CarPlay and Android Auto.

The SLE Package

For a few bucks more, you can upgrade to the SLE trim level which gets you everything offered in the base package while upgrading to an eight-inch infotainment system along with super cool flairs such as body-colored door handles and remote keyless entry.

It also sports an all-new integrated trailer brake controller and complete side-window surround.

Power Up to the SLT

The SLT is where you really start getting into some of GMC’s most exciting and desirable features.

With everything offered at the SLE level, all of your bases are covered.

But add on a six-function MultiPro tailgate and a ProGrade trailering system, the work is easier than ever. And that’s not to mention the ten-way power leather front seats, auto-dimming mirrors, and hi-def rearview camera, all of which add up to equal the ultimate comfort.

AT means All-Terrain

If you’re looking to have some more fun in the mud, then the AT4 is your trim level.

Featuring everything mentioned above plus a gnarly two-inch lift with off-road suspension and Rancho shocks, an Eaton locking differential, and unstoppable all-terrain tires, you won’t find a trail you can’t conquer in your 3500.

The Grandaddy of them All

The Denali is GMC’s top-of-the-line trim level, one that blends luxury with attitude, all while maintaining the signature strength you’ve come to expect from a GMC Sierra 3500.

The Denali trim level gets you everything at the SLT level plus an electronic two-speed AutoTrac transfer case, Forge leather seats, built-in navigation, ash wood, brushed aluminium, and chrome accents, and a premium Bose audio system.

It doesn’t get much more luxurious and inviting than the 3500 Sierra Denali.
