About This 2024 GMC Sierra 2500 HD Double Cab

At 96,409 miles, this Sierra 2500 HD sits firmly in the sweet spot for a used heavy-duty diesel truck. Diesel engines — especially the 6.6-liter Duramax found in this generation Sierra HD — are famously built for the long haul. Many owners routinely push 250,000 to 300,000 miles with proper maintenance, meaning this truck has a tremendous amount of life left in it. The 2024 model year also means you're getting one of the most refined iterations of GM's third-generation HD platform, with updated technology and build quality that rivals far newer trucks on the market. Whether you're hauling equipment across Stanislaus County or towing a fifth-wheel through the Central Valley, this truck is purpose-built for the task.

2024 GMC Sierra 2500 HD Performance and Engine

6.6-Liter Duramax Diesel Power

Under the hood sits GMC's 6.6-liter Duramax V8 diesel, producing 470 horsepower and a massive 975 lb-ft of torque in this generation. That torque figure is what separates a true heavy-duty truck from everything else on the road — it means confident towing capacity rated up to 18,500 lbs when properly equipped, and best-in-class pulling whether you're on the freeway or crawling through a job site.

10-Speed Allison Automatic Transmission

Paired to that engine is the legendary Allison 10-speed automatic — a transmission that commercial fleets and long-haul operators have trusted for decades. The Allison is not a badge or a marketing claim; it's a genuinely heavy-duty unit with integrated exhaust braking and dedicated tow/haul programming that changes how the truck downshifts under load. Real-world drivers consistently praise it for smooth power delivery and heat management under sustained towing stress.

Four-Wheel Drive Capability

The four-wheel drive system gives this Sierra 2500 HD the ability to tackle muddy job sites, wet agricultural fields, and the occasional Sierra Nevada backroad with equal confidence. Whether you need 4-High for slick highway conditions or 4-Low for crawling, this truck handles it without hesitation.

GMC Sierra 2500 HD SLE Features and Interior

The SLE trim represents a meaningful step up from the base WT model, adding a layer of comfort and technology that makes long days on the road or the job site far more bearable. Inside, you'll find GMC's infotainment system with a large touchscreen, Apple CarPlay and Android Auto compatibility, Bluetooth connectivity, and USB inputs for keeping devices charged during long hauls. The Double Cab configuration provides a genuine rear seat with enough room for crew members or family — a step up from a regular cab without the added length of a full crew cab. The 8-foot bed adds serious usability for those who need maximum cargo space, whether that's lumber, tools, or towing a gooseneck trailer.

GMC Sierra 2500 HD Reliability and Ownership

The Duramax/Allison combination in the Sierra 2500 HD has earned a reputation as one of the most dependable diesel pairings in the light-heavy-duty segment. Unlike some competitors, GM's decision to use the Allison transmission rather than its own in-house unit speaks to a commitment to durability over cost-cutting. Owners consistently report that these trucks hold up exceptionally well when maintained on schedule — particularly oil changes using the correct diesel-rated oil, fuel filter replacements, and DEF fluid top-offs. The 2024 model year benefits from a refined emissions system and updated electronics that addressed earlier quirks found in the 2020-2021 model years. For buyers purchasing a work truck with high mileage, a pre-purchase inspection with records review is always a smart step — but know that these engines are designed from the ground up to go the distance.
