GMC Sierra 2500 Trims and Packages

The GMC Sierra 2500 is a heavy-duty truck that can take on the toughest work jobs. This vehicle can help you tow up to 18,500 pounds, and it also has a lot of great interior and technology features.

However, there are several different trim levels for the GMC Sierra 2500. How do you know which one is right for you? Below, we will take a closer look at the performance that the GMC Sierra 2500 HD can offer you. Then, we will take a closer look at the different trim options and what features they offer you.

Engine Options:

  • 6.6-liter V8 – The base engine in the Sierra 2500 is the 6.6-liter V8 gasoline engine that gives you 401-horsepower and 464 pound-feet of torque. This engine is paired with a six-speed automatic transmission.
  • 6.6-liter Turbo-diesel V8 – Your other engine option is the 6.6-liter Duramax Turbo-Diesel engine. This diesel engine option gives you 445-horsepower and 910 pound-feet of torque. This engine is paired with an Allison 10-speed automatic transmission.

Both of these engine options are available in all of your Sierra 2500 trim levels, and when this vehicle is properly equipped, it can tow up to 18,510 pounds.

Cab Options:

  • Regular Cab – The regular cab option has just one row of seating with seating for up to three people. This cab option can be found on your lower trim levels of the Sierra 2500 HD, and it comes with the 8-foot long bed.
  • Double Cab – The double cab has two rows of seating, and it is available on the first few trims options in the Sierra 2500 HD. You have more seating with this cab option, and you have the choice of two bed options to pair with it. You can get an 8-foot long bed or a 6-foot-9-inch bed.
  • Crew Cab – The crew cab offers you the most spacious interior space and comfort for your passengers with more rear-seat room than the double cab option. The crew cab is standard on the upper Sierra 2500 trims like the AT4 and the Denali. Like the double cab, this option can be found with the long bed or the standard bed.

Now that we have talked about your engine, cab, and bed options for your Sierra 2500 HD, we are going to discuss the different trim levels. Check it out below.


The base trim for the GMC Sierra 2500 HD will be your most affordable option, but it will not give you as many features as the higher trim levels.

The base model starts out with features like LED headlamps and LED daytime running lamps. It also gives you Bluetooth capability, a GMC infotainment system with a touchscreen, and a rear vision camera.

This base Sierra 2500 HD is nothing super fancy, but it is affordable and will help you get the job done. If you are on a budget, and you are not looking for any extra frills, this could be the trim option for you.


The SLE trim adds some technology features to keep you more connected. You also get some features to make storage and cargo more convenient.

Technology features found on the Sierra 2500 SLE include remote keyless entry and the capability for a 4G LTE Wi-Fi hotspot and OnStar Connected services. This can help you stay more connected to technology and safety services. The SLE also gives you features like a tailgate with EZ lift and lower assist, a front bench seat with under-seat storage, a leather-wrapped steering wheel, and cloth seat trim.

The SLE trim is great for those that want a few extra technology features, but they are still looking to get a pretty affordable truck option.


This trim level adds even more features for your style, comfort, and convenience. You get some additional exterior features, as well as some features on the inside of the vehicle.

On the outside of the SLT trim, you get features like 18-inch aluminum wheels, the GMC MultiPro Tailgate, LED lighting for the cargo bed, LED daytime running lamps, and power-adjustable trailering mirrors. The MultiPro Tailgate makes it easy to get access to your cargo bed, and it offers multiple configurations to help your work. The power-adjustable trailering mirrors can fold and extend depending on your needs, and they can help you keep better track of your cargo.

The 2500 SLT interior offers you perforated leather-appointed front seat trim. You also get heated front seats and available ventilated front seats. There is a six-speaker audio system, remote start, keyless entry, an infotainment system with an 8-inch touchscreen, and hitch guidance with hitch view.

If you are looking for a really nice interior and some extra function with your cargo bed, you probably want to step it up to the SLT trim. This trim level offers you features to make work easier, and make your drive more comfortable.


In the AT4, you have some ways to upgrade the performance of your heavy-duty truck. This trim level is designed for more off-road type performance. This trim level gives you the Allison 10-speed automatic transmission standard, as well as a lifted suspension and underbody protection. You also get 18-inch machined aluminum wheels and an Autotrac two-speed transfer case.

To enhance your driving and riding experience, the interior of the AT4 offers you ventilated front seats, heated front and rear seats, leather front seats trim, front bucket seats, and upgraded rear seats with extra storage. There is also an available sunroof and all-weather floor mats with the AT4 logo.

The AT4 trim is the right option for you if you are looking for something that is more adventurous and off-road capable.


The Sierra 2500 HD Denali is your highest trim option. This vehicle offers you the most luxurious experience of your trim levels. You get features like polished exhaust tips, IntelliBeam lights, and Smoked Amber LED roof marker lamps.

With this vehicle, you get the Crew Cab model, so you have front bucket seats, as well as a large second row of seating for added passenger comfort. The Denali also gives you a Bose premium sound system to help you enjoy your listening experience. The GMC infotainment system in the Denali has an 8-inch touchscreen and a navigation system. Your vehicle also gives you wireless device charging to keep you connected.

If you are looking for the most high-end interior in your GMC Sierra 2500 HD, the Denali trim is the right choice for you. This trim offers you interior features like heated and ventilated seats and wireless device charging.

There are five different trim options available in the GMC Sierra 2500 HD. These five trim levels are all worth considering, but you have to decide which features are most important for you when it comes to your next truck. The Sierra 2500 gives you the choice of two engines that can be put in any of the trims, so you should take a look at some of the other features to help you determine which is right for you.
