Full specifications for the fourth-generation GMC Sierra 1500 (T1XX, 2019 on), by engine. The Sierra 1500 is the mechanical twin of the Chevrolet Silverado 1500, so these figures apply to both. Note the mid-cycle changes: the 2.7L turbo jumped from 348 to 430 lb-ft for 2022, and the 3.0L Duramax rose from 277 to 305 hp for 2023. Dimensions are Crew Cab short box; fluids and capacities are from the owner manual.
Each column is one specific vehicle — a single engine or motor and, where shown, body style. Dimensions and several weights are specific to that body and drivetrain; other body or powertrain versions differ, so match the column to your own vehicle.

Frequently Asked Questions
What engines does the T1XX Sierra 1500 offer?
A 310 hp 2.7L turbo-four, a 285 hp 4.3L V6, a 355 hp 5.3L V8, a 420 hp 6.2L V8, and a 3.0L Duramax turbo-diesel inline-six.
