Frequently Asked Questions
Which engine option delivers the highest towing capacity for each model?
For Silverado 1500, the 3.0-liter Duramax Turbo-Diesel inline-six and the 6.2-liter gasoline V8 both allow towing near 13,300 pounds. For Silverado 2500HD, the diesel V8 achieves the highest rating, up to approximately 22,420 pounds with gooseneck or fifth-wheel setups.
Does four-wheel drive affect towing capacity?
Capacities vary slightly by drivetrain and configuration. The highest conventional towing values for the 1500 and 2500HD are often available in both rear-wheel and four-wheel drive, but payload and hitch ratings depend on cab style, bed length, wheel size, and towing package.
Is payload capacity included in towing ratings?
No. Payload refers to the weight carried in the truck bed and cabin, not on a trailer. Maximum towing ratings assume that payload limits are not exceeded. For example, payload may range from roughly 1,870 to 2,260 pounds on Silverado 1500, depending on engine and cab configuration.
