The 2021 GMC Sierra 2500HD Base Double Cab 4x4 isn't just a truck it's a hard-working, high-capability machine built to handle everything the Pacific Northwest can throw its way. Whether you're towing gear into the mountains, navigating forest service roads, or putting in long days on the job site, this Sierra HD is built for people who need power, purpose, and reliability every single day. With only 46,268 miles, a thorough reconditioning, and a work-ready spirit, it's ready to go the distance.
Under the hood lies the muscle of a 6.6L V8 paired with a robust 6-speed automatic transmission, delivering serious towing and hauling power backed by a 3.73 rear axle and an integrated trailer brake controller. This truck doesn't flinch at steep terrain or heavy loads, and its 2-speed electronic shift transfer case and 4WD system give you confident traction on snowy passes, gravel backroads, or muddy trails in the Cascades. Thanks to the X31 Off-Road Package and off-road suspension, it handles uneven ground with ease, while Hill Descent Control adds peace of mind when the descent gets steep.
Finished in Summit White with classic steel 18-inch wheels and a chrome-surround grille with black mesh, it has a rugged, no-nonsense presence. The spray-in bedliner with GMC logo, EZ Lift tailgate with power lock and release, 120V bed-mounted outlet, and upfitter switch kit ensure this truck works as hard as you do, whether you're wiring tools on the go or running a mobile workbench out of the back.
Inside, the Jet Black cloth interior offers straightforward comfort, with power rear windows and steering-wheel-mounted cruise control to make long drives more manageable. The cabin is modern but durable fitting for a rig that may spend as much time in the dirt as it does on the pavement. Stay connected and focused with the GMC Infotainment System featuring Apple CarPlay and Android Auto, Bluetooth hands-free functionality, and a six-speaker audio system. The rearview camera and reverse sensing system make maneuvering easier, even in tight urban job sites or dense trailheads.
This Sierra 2500HD feels right at home pulling a boat out to Lake Chelan, towing a trailer full of lumber through the Columbia River Gorge, or hauling gear to your remote cabin in the Olympics. It's a capable, honest truck built for the doers, explorers, and professionals who keep the Pacific Northwest running and who need a rig that can keep up with their drive.

Transmission trash
By Jason on Monday, April 07, 2025
Bought a 2023 GMC Duramax diesel Sierra SLT had it for two years hit 50,000 miles. The throttlebody broke went in for service. Got it back three weeks at 62,000 miles now my transmission is slipping. I travel back-and-forth from South Carolina to North Carolina for work daughter’s truck would be my forever truck. What a joke Hundred thousand dollar truck junk - 5.0
Fantastic truck
By Jjj on Sunday, November 07, 2021
This one of the most solid vehicles that I have ever driven! The 401 hp engine is more than enough power and the transmission is smooth! Highly recommend this truck! - 3.0
Don't judge a truck by the appearance
By jmil on Wednesday, May 11, 2022
Great truck, loved it until the DEF tank heater malfunctioned and shut down the truck. Now sitting waiting for the replacement tank for over 10 weeks. Turns out every HD truck 2020 and 2021 has the same problem and all will need this replacement that is being produced at a snail's pace by GM. Per the dealership, last count, over 9000 trucks like mine are idle waiting for this part. $65000 waste of money and terrible service by GMC (not the local dealership).
