The Silverado HD comes in five trims – WT (Work Truck), Custom, LT, LTZ, and High Country – and two versions, 2500 HD and 3500 HD (the Custom trim is available only as the 2500 HD). Chevrolet also offers three cab styles: regular (two doors), Double Cab (two standard front doors and two rear-access doors), and Crew Cab (four standard doors). There are also two bed lengths: standard (82.25 inches) and long (98.27 inches). In addition, the 3500 HD can be configured with either a single-rear-wheel or dual-rear-wheel setup. Cab style and bed length availability vary by trim and version.
Payload and towing capacities vary by cab style, bed length, engine, and equipment. The 2500 HD has a maximum payload limit of 3,615 pounds, compared to 6,859 pounds for the 3500 HD. For conventional towing, the 2500 HD and 3500 HD can handle up to 20,000 pounds. With fifth-wheel/gooseneck hauling, towing maxes out at 22,430 pounds for the 2500 HD and 36,000 pounds for the 3500 HD.
A 6.6-liter gasoline V8 (401 horsepower and 464 lb.-ft. of torque) is the standard engine for all Silverado HDs. The optional Duramax 6.6-liter V-8 turbo-diesel makes 470 horsepower and 975 lb.-ft. of torque. Both powerplants are managed through a heavy-duty Allison ten-speed automatic transmission. Rear-wheel drive is standard, with four-wheel drive (4WD) offered as an option. The High Country is 4WD-only.
The WT is focused on getting the job done with a relatively basic list of features. It has manually controlled air conditioning, a 40/20/40 split-bench front seat, vinyl upholstery, vinyl flooring, remote keyless entry, a 3.5-inch monochromatic driver information display, a locking tailgate, halogen headlights, a trailering package, power windows and door locks, black-finish exterior accents, and 17-inch steel wheels. The Custom takes the Silverado HD up a notch with fabric-upholstered seating, carpeted floors, rubberized floor mats, deep-tinted glass, power exterior trailering mirrors, cruise control, body-color bumpers, and 20-inch aluminum wheels.
The outward changes for the LT include an EZ Lift tailgate with power lock and release, chrome bumpers, body-color exterior accents, and 17-inch aluminum wheels. Inside, this mid-tier Silverado HD gets a 12.3-inch driver information display, proximity keyless entry with push-button start, steering-wheel-mounted controls, and a wrapped steering wheel.
The LTZ trim has been the most extensively updated, getting LED fog lamps, enhanced side mirrors with a power-folding/extending feature, rain-sensing windshield wipers, remote start, rear wheelhouse liners, LED exterior lighting, and chrome exterior accents. Its cabin now has leather upholstery, a heated steering wheel, dual-zone automatic climate control, heated driver and front outboard passenger seats, 10-way power driver’s and front passenger’s seats, a driver’s position memory system, 120-volt power outlets, a manual tilt-and-telescopic steering column, an auto-dimming rearview mirror, a rear-window defogger, and an enhanced rear seat with under seat storage.
At the apex of the lineup, the High Country adds the most premium touches, including a power tailgate, 6-inch chrome assist steps, body-color bumpers, a spray-on bed liner, and 20-inch chrome wheels. It also has heated and ventilated front bucket seats with perforated leather upholstery, a front center console, heated rear outboard seats, and a power-sliding rear window.
All 2024 Silverado HDs come with forward collision warning, automatic emergency braking with pedestrian detection, lane departure warning, and a following distance indicator. A full set of airbags, anti-lock brakes, traction control, vehicle stability control, and a rearview monitor are also found on all trims.
Blind-spot monitoring and rear cross-traffic alert are optional on the WT through LTZ, and the High Country gets an upgraded blind-spot system that supports trailering (this feature is optional for the LTZ). The High Country also comes with the Safety Alert Seat (which vibrates the driver seat when there’s a safety-related notification) and front and rear parking sensors—both are optional on the LTZ. Also standard on the High Country are a bed-view monitor (optional on the lower trims) and a surround-view monitor (available on the LT and LTZ).
A 7-inch touchscreen is the multimedia nerve center for the WT and Custom. It unites a multi-speaker audio system, wireless Android Auto and Apple CarPlay, and Bluetooth. The LT and higher move up to a 13.4-inch touchscreen. SiriusXM satellite radio is optional on the WT and included with the higher trims. A seven-speaker Bose sound system and wireless device charging come on the High Country and are optional on the LTZ. All Silverado HDs have access to a Wi-Fi hotspot, Chevrolet connected services, and OnStar.
