When equipped with the available GM 3.0L LM2 inline-six turbodiesel, the 2021 Chevrolet Silverado offers an additional 1,900 pounds of trailering capacity to “nearly every configuration,” General Motors says, with two-wheel-drive models able to tow up to 9,500 pounds. Chevrolet has also taken $1,500 off the MSRP for the diesel engine for 2021 models, potentially making the engine a viable option for more fleets.
The 2021 Chevrolet Silverado with the 2.7L L3B and four-wheel-drive also now boasts a superior towing capacity to the 3.0L LM2 Duramax model with the four-wheel-drive, beating it by 300 pounds at a capacity of 9,400 pounds. The GM 6.2L L87 V8 model still boasts the highest towing capacity of any 2021 Chevrolet Silverado 1500 engine, however, at 13,400 pounds.
GM said that it was able to unlock increased towing numbers for the 2.7L L3B engine after additional testing and validation revealed that it “possesses better-than-expected cooling performance.” The improvements to the 3.0L Duramax model’s towing capacity weren’t related to powertrain improvements, but rather the Silverado’s better-than-expected rear axle durability. GM engineers recertified both models under the SAE J2807 standard for 2021 to confirm its increased towing numbers for these two engines,
GM introduced a number of changes and improvements to the Silverado 1500 for the 2021 model year, including the new Multi-Flex tailgate, new exterior colors, new standard features, and new packages and content.
