2026 GMC Sierra EV
GMC lists a maximum of 12,500 lb on a conventional hitch for the 2026 GMC Sierra EV in its 2026 Sierra EV Max Trailering. That rating requires the Elevation Extended Range, or Denali Extended Range with 11 kW AC charging and coil suspension; dual-motor e4WD Crew Cab. Most configurations are rated lower: 5 of the 7 transcribed conventional-hitch chart rows for 2026 are below 12,500 lb. Across 7 manufacturer chart rows for 2026, ratings run conventional 8,500 lb to 12,500 lb; the engine, cab, axle ratio and package on your truck decide its number.
The build table for 2026 is not transcribed. This page will not multiply trims, cabs, and engines into trucks the order guide did not list.

Battery and trim change the rating. This chart ranges from 8,500 to 12,500 lb. Its maximum is not a payload figure or a towing-range estimate.
Source: GMC, 2026 Sierra EV Max Trailering, Page 1, all seven Crew Cab rows and footnotes 1–3. Trim/battery-level maxima, not VIN-specific limits. Denali Extended Range requires 11 kW AC charging and coil suspension for the listed maximum. Bed dimensions and payload are not stated in this chart.

Bed, tongue weight, and wheelbase
The trailer rating is one limit. The bed has to fit the load, the tongue or pin has to fit in payload, and the wheelbase is the column the chart uses.
- An illustrative 10 percent of the 12,500 lb conventional maximum is 1,250 lb of tongue weight. This is not a measured load or recommended percentage; actual load may be higher.

2026 is year 3 of this generation (2024–2026). Electric Sierra. No cited towing chart is on file.
2026 towing by engine
Lowest to highest printed rating for each engine across 7 transcribed chart rows. A missing hitch means the chart did not print one for that engine, not that it is zero.

Questions
- How much can a 2026 GMC Sierra EV tow?
- GMC lists a maximum of 12,500 lb on a conventional hitch for the 2026 GMC Sierra EV in its 2026 Sierra EV Max Trailering. That rating requires the Elevation Extended Range, or Denali Extended Range with 11 kW AC charging and coil suspension; dual-motor e4WD Crew Cab. Most configurations are rated lower: 5 of the 7 transcribed conventional-hitch chart rows for 2026 are below 12,500 lb.
- Did Sierra EV towing change for 2026?
- Nothing on file says the published maximum changed for 2026. That is not the same as proof that it stayed the same.
- Which configuration hits the maximum?
- The 12,500 lb conventional maximum requires the Elevation Extended Range, or Denali Extended Range with 11 kW AC charging and coil suspension; dual-motor e4WD Crew Cab.
- What tongue weight should I plan for a 2026 Sierra EV?
- At the cited 12,500 lb conventional maximum, an illustrative 10% assumption produces 1,250 lb of tongue weight. This is not a recommended percentage or a measurement; follow your trailer and vehicle instructions and measure the actual load. That load counts against payload and the rear axle rating.
