Robert Brogden's Garden City GMC

Aug 17, 2026

If your work demands serious towing and hauling, the 2026 GMC Sierra 2500 HD and 3500 HD were built for exactly what you do. Whether you’re pulling a loaded livestock trailer out of Dodge City, hauling heavy equipment across the Kansas plains, or running a flatbed from Garden City to Wichita, these trucks deliver the muscle and technology to get the job done right. At Robert Brogden’s Garden City GMC, located at 409 E Fulton St in Garden City, KS, the full 2026 Sierra HD lineup is here and ready to work.

Built for Western Kansas: Meet the 2026 GMC Sierra 2500 HD

The 2026 GMC Sierra 2500 HD is the heavy-duty truck for buyers who need maximum capability without stepping up to a full Class 3 machine. With a maximum towing capacity of 22,390 lbs and a payload of up to 4,049 lbs, it handles the kind of loads that would leave a half-ton truck sweating. Whether you’re towing a horse trailer from Scott City or running a large enclosed cargo trailer across the region, the 2500 HD stays composed and in control.

The standard 6.6L V8 gas engine produces 401 horsepower and 464 lb-ft of torque, paired with a smooth-shifting Allison 10-speed automatic transmission. That combination delivers confident acceleration under load and better fuel management across long highway miles — important when you’re covering ground between Garden City, Great Bend, and Pratt on a regular basis.

Go Heavier: The 2026 GMC Sierra 3500 HD for Serious Hauling

When the job requires more, the 2026 GMC Sierra 3500 HD steps up in a serious way. With gooseneck towing capacity reaching 36,000 lbs and a maximum payload of 7,290 lbs, this is the truck for large grain hoppers, commercial equipment, and heavy livestock rigs common across Western Kansas and into the Oklahoma Panhandle near Guymon.

The 3500 HD is also available with dual rear wheels (dually configuration), which adds lateral stability under heavy gooseneck and 5th-wheel loads. If your operation regularly moves loads that push the upper limits of what any truck can tow, the 3500 HD is the right tool for the job.

Diesel or Gas? Choose the Right Engine for Your Work

Both the Sierra 2500 HD and 3500 HD are available with the legendary Duramax 6.6L Turbo-Diesel V8, which cranks out a massive 975 lb-ft of torque — paired with that same Allison 10-speed automatic. That torque figure is especially relevant when you’re climbing grades or pulling fully loaded trailers at lower speeds where diesel torque shines.

The gas 6.6L V8 is an excellent choice if you’re doing lighter-duty towing, want simpler maintenance, or are more budget-conscious on the front end. Your Brogden sales team can walk you through the towing math based on what you’re actually hauling and help you choose the engine that makes the most sense for your operation.

Both trucks also come equipped with GMC’s ProGrade Trailering System, which includes up to 14 camera views — including a transparent trailer view — making hookup and lane changes safer and less stressful, even when you’re doing it solo.
