History/Overview
The GMC Sierra HD is the heavy-duty pickup for drivers who need more capacity and capability than the more common, light-duty 1500 can offer. This is the fourth model year for this current, fifth-generation version of the truck.
What’s New/Key Changes From Last Year
There are no changes to the Sierra HD range for 2023; we were expecting a significant refresh, but that has been put off until 2024.
Available Trims
The GMC Sierra HD comes in Pro, SLE, SLT, AT4, and Denali trims. You can get two- or four-wheel drive; regular, Double Cab and Crew Cab configurations; and standard and long beds sizes. The standard powertrain is a 6.6L gas V8 and a six-speed automatic transmission, the option being a 6.6L diesel/10-speed auto combination.
Standard Features
Sierra HD Pro gets a 7.0-inch touchscreen, smartphone integration, LED headlights, 17-inch wheels, bed steps, trailering side mirrors, cargo lights/tie-downs, and chrome bumpers. The seats and floors are finished in vinyl, and there’s a six-speaker stereo.
SLE trim brings a trailer brake controller, a MultiPro tailgate, leather-wrapped wheel, cruise control, keyless entry, and satellite radio.
SLT gains 18-inch wheels, LED bed lights and fog lamps, power folding/extending side mirrors, hitch guidance, trailering app, and an easy-lift tailgate. Inside, there are power-adjustable heated seats, a heated steering wheel, 8.0-inch infotainment screen, dual-zone A/C, and passive keyless entry.
