About This 2017 GMC Sierra 2500 HD Crew Cab

At just under 90,000 miles, this 2017 Sierra 2500 HD sits in a sweet spot for used heavy-duty truck buyers. Diesel trucks built on the Duramax platform are well-known for lasting well beyond 200,000 miles with proper maintenance, meaning this truck likely has the majority of its working life still ahead of it. The crew cab configuration gives you four full-size doors and a real back seat — not an afterthought — making this equally useful for hauling a crew to the job site and taking the family out on weekends. The 6.5-foot bed adds genuine cargo flexibility without sacrificing too much in overall maneuverability.

2017 GMC Sierra 2500 HD Performance and Engine

Duramax 6.6L Turbodiesel V8

The heart of this truck is the iconic 6.6-liter Duramax turbodiesel V8, paired with a 6-speed Allison automatic overdrive transmission — widely considered one of the best diesel powertrain combinations ever put into a pickup truck. In 2017 trim, this engine produces around 445 horsepower and 910 lb-ft of torque, giving this Sierra a maximum tow rating of up to 18,100 pounds when properly equipped. The Allison transmission is a commercial-grade unit that earns its own devoted following among heavy-duty truck owners — it shifts smoothly under load and is built to handle years of hard use.

The 4WD drivetrain means you're not limited to smooth surfaces. Whether you're pulling a fifth-wheel trailer through mountain terrain or navigating a muddy worksite, this truck has the mechanical capability to handle it.

GMC Sierra 2500 HD SLT Features and Interior

SLT Trim — Premium Without the Premium Price Tag

The SLT sits just below the top-of-the-line Denali in GMC's lineup, which means you get a long list of upscale features without stepping all the way up to flagship pricing. Expect leather-appointed seating, heated front seats, a power driver's seat, wood-grain interior accents, and GMC's IntelliLink infotainment system with an 8-inch touchscreen, Bluetooth connectivity, and available navigation. The crew cab interior is genuinely spacious — rear passengers have adult-worthy legroom, and the rear seat can fold up for additional storage.

On the outside, the SLT typically adds chrome accents, body-color trim, and 18-inch alloy wheels that give this white truck a polished, professional appearance — the kind of rig that looks sharp on a job site and equally at home in a parking lot.

GMC Sierra 2500 HD Reliability and Ownership

The 2017 Sierra 2500 HD benefits from a powertrain combination that's earned decades of real-world credibility. The Duramax L5P engine — introduced for the 2017 model year — was a significant update over its predecessor, featuring improved fuel injection, better emissions management, and more robust internal components. Owners consistently report strong long-term reliability when maintenance intervals are followed, particularly around oil changes, fuel filter replacements, and DEF (diesel exhaust fluid) top-offs.

The Allison 1000 transmission shares a similar reputation. It's used in commercial applications far beyond light-duty trucks, and its durability record is exceptional. For buyers looking at a truck they intend to own and depend on for years — not just a few — the Sierra 2500 HD with this powertrain is a smart, well-documented choice.

Frequently Asked Questions

Is the 2017 GMC Sierra 2500 HD a good buy?

Yes — the 2017 model year marked the introduction of the updated L5P Duramax engine, making it one of the most capable and refined Sierra 2500 HD trucks ever built. The Allison transmission pairing is a proven workhorse, and the SLT trim adds enough comfort features to make it livable as a daily driver, not just a work truck.

How many miles is too many on a used diesel truck?

It's a significant step up from the SLE without reaching the full Denali price point.
