The GMC Sierra 2500 is a beautiful truck inside and out. However, being a capable vehicle is more than just aesthetics. You want a truck tough enough to get the job done when you put it to the test.

If you plan on towing, you need a vehicle built with it in mind. So what’s the GMC Sierra 2500’s towing capacity? Is it good for towing?

Let’s look below the surface of this gorgeous truck and see.

What Is Towing Capacity?

Towing capacity is the maximum weight a vehicle can legally and safely tow. The vehicle manufacturer sets this important tow rating.

While you can have two similar-looking vehicles, they could have very different towing capacities based on the options selected for a specific vehicle. If you plan to do any towing, you must know your vehicle’s towing capacity.

Why Does Towing Capacity Matter?

Exceeding a vehicle’s towing capacity is not only illegal but can jeopardize the safety of everyone on the road.

If that’s not enough, towing a load over a vehicle’s capacity increases the likelihood of trailer sway. Additionally, it puts unnecessary wear and tear on a vehicle’s suspension and powertrain.

Many drivers make the mistake of exceeding their towing capacity. They do this because they know their vehicle is strong enough to pull more weight.

However, what many drivers need to remember is the vehicle not only has to be able to pull the load but also stop it. Exceeding the towing capacity greatly increases the amount of stopping distance necessary to come to a complete stop.

About the GMC Sierra 2500

GMC released the Sierra line of trucks starting in 1987 and introduced the fourth generation in 2013.

They’ve made modifications and improvements with each new generation. Today, they’ve created a vehicle that looks good and exceeds most drivers’ expectations.


The GMC Sierra 2500 comes in five different models. The GMC Sierra 2500 PRO is the entry-level vehicle, and then you work your way up through the various trims with the SLE, SLT, AT4, and the Denali sitting at the top.

Don’t underestimate the base-level models just because they may not have the same fancy features as the more luxury trim models.

If you’re looking for the most capable GMC Sierra 2500 for towing, you’ll need to stick with the PRO or SLE models. Of all the models, they provide the highest towing capacity and payload.

While some of the fancy features are nice and make for a more comfortable ride, they add weight to the vehicle and retract from its towing and hauling capabilities.

The GMC Sierra 2500 features a strong and capable 6.6-liter turbo-diesel V8 engine or a 6.6-liter V8 gas engine.

In addition, drivers can choose a six-speed heavy-duty, electronically controlled automatic transmission or the impressive 10-speed automatic Allison transmission. The Sierra 2500 can crank 445 horsepower and 910-foot pounds of torque when fully equipped. 

With several upgrade packages available, upgrading to the X31 off-road package transforms the truck into an off-roading machine.

It has twin-tube rancho shocks and skid plates to protect your sensitive components. You’ll enjoy a smooth and comfortable ride over the most rugged terrains.

Standout Features

Some of the standout features of the GMC Sierra 2500 include the heads-up display and rear camera mirror. These features help keep your eyes on the road and give you a crystal clear image of what’s happening behind you.

In addition, the GMC Sierra 2500 features a six-function multipro tailgate that can serve as a workbench for getting projects done or secure loads. 

Other features that help the GMC Sierra 2500 separate itself from the rest are the 15 camera views on some models and the best-in-class cargo bed volume.

You’ll be able to haul gear, supplies, and equipment whether you’re heading to the job site, your next weekend project, or on a camping adventure.
