Structural benchmarks demonstrate a Gross Combination Weight Rating (GCWR) spanning 24,000 to 27,500 lbs, a Gross Vehicle Weight Rating (GVWR) from 10,000 to 11,350 lbs, unladen curb weights between 6,200 and 7,800 lbs, and certified static tongue weight limits ranging from 1,450 to 1,850 lbs.
Worksite productivity is backed by the Sierra 2500HD max payload rating, which ranges from 3,715 lbs on Duramax models up to 3,965 lbs on gas platform setups. Built on a hydroformed, fully boxed high-strength steel frame with heavy-duty leaf springs, the heavy-duty pickup maintains flat towing stance and precise front-axle steering response under load. Models equipped according to factory tow package specifications include a heavy-duty Class-V hitch receiver, 7-pin electrical harness, integrated trailer brake controller, digital variable steering assist, and an available smart trailer camera suite. The Duramax Diesel engine incorporates an integrated smart exhaust brake to minimize service brake wear on long mountain descents.
