Full specifications for the K2XX Chevrolet Tahoe (2015-2020), by engine — the 5.3L V8 (all years) and the 6.2L V8 (2018-2020, RST/Premier). Output, towing and dimensions are cross-checked; fluids and capacities are from the owner manual. The Suburban is the long-wheelbase twin.
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.

Sources: Owner's manual · Workshop data. Where an owner’s manual or homologation figure exists it takes precedence; workshop data fills only what those omit.
A dash (—) means we haven’t verified that figure for that variant yet. Figures are US-market. Towing, payload and weights are best-case/config-dependent — your door-jamb label is the authority.
