Drive the 2026 GMC Sierra 2500 HD — Heavy-Duty Muscle for Citrus County
If you're shopping for the 2026 GMC Sierra 2500 HD, Eagle Buick GMC in Homosassa has the trim, the towing capacity, and the local reputation to back up the sale. Whether you're hauling a camper out of Crystal River, pulling equipment around a Hernando County job site, or running livestock trailers near Chiefland, the 2500 HD is built for exactly that work — and we've been the hometown dealer Citrus County trusts to sell it since 1986.
Meet the 2026 GMC Sierra 2500 HD — Heavy-Duty Power for Citrus County
The 2026 Sierra 2500 HD is GMC's answer for buyers who've outgrown a half-ton truck. It's built on a heavy-duty frame with the suspension, brakes, and drivetrain to match serious towing and payload demands, and for 2026 it comes in seven distinct trims so you can spec it for exactly how you use it — whether that's a work truck for a Brooksville contractor or a loaded-up Denali Ultimate for weekend towing.
Buyers across Citrus, Hernando, and Sumter counties choose the 2500 HD for the same reason: half-ton trucks max out fast once you're loading a gooseneck trailer, a skid steer, or a fully loaded horse trailer. The 2500 HD gives you the margin to tow and haul without living at the edge of your truck's limits every trip.
Trim Levels Explained: Pro, SLE, SLT, AT4, AT4X, Denali & Denali Ultimate

Towing, Payload, and Engine Options
Every 2026 Sierra 2500 HD trim is available with your choice of two engines: the standard 6.6L V8 gas engine (401 hp, 464 lb-ft of torque) or the 6.6L Duramax Turbo-Diesel V8 (470 hp and 975 lb-ft of torque), both paired with the Allison 10-speed automatic transmission. Properly equipped, the 2500 HD is rated for up to 22,390 lbs of conventional towing and up to 4,049 lbs of maximum payload — enough for horse trailers, construction equipment, and fifth-wheel campers alike. Whichever engine and trim fits your budget, our sales team can walk you through exactly what configuration hits the towing number your specific trailer or equipment requires.
