As soon as GMC announced its first ever Sierra HD Denali Ultimate, speculations around the pickup truck and GMC claims about its features arose. Both The Sierra 2500HD and 3500 HD are getting an inside out update in the 2024 model. A boost in diesel power, an ultimate luxury trim and an AT4X off the road trim on the horizon, GMC is really building up on its long time glory.
“The new and enhanced 2024 Sierra HD builds on an already winning foundation,” said Duncan Aldred, vice president of Global Buick and GMC. “This truck elevates the HD segment with the introductions of the Denali Ultimate trim and will soon add the seriously off-road capable AT4X trim, further strengthening the dominance of the GMC truck portfolio.”
The 2024 Sierra HD lineup includes 2500HD and 3500HD models, in Regular Cab, Extended Cab and Crew Cab configurations — with dual-rear-wheel models available on 3500HD. They support the lineup’s highest trailering capacity: up to 36,000 pounds4. Available trims include Pro, SLE, SLT, AT4, Denali and Denali Ultimate, with the AT4X trim coming later in the model year.
