Chevrolet Commercial just announced a slew of updates for the Chevrolet Silverado MD truck lineup at the ongoing NTEA Work Truck Show. The updates will be applied for the 2021 model year on the Silverado 4500 HD, 5500 HD, and 6500 HD chassis cab trucks.
“Continuing to listen to its customers, Chevrolet is bringing a host of updates to medium-duty chassis cabs to further increase performance and flexibility for upfitting,” the automaker states in a press release.
Highlights include a 23-percent increase in hauling capability, with maximum gross combined weight now rated at 37,000 pounds. Additionally, the Chevrolet Silverado MD trucks now have a new mechanical locking rear axle that will automatically lock when tire slippage occurs, improving traction on slippery road surfaces or off-road.
Inside, there is a new auxiliary switch bank offered with six additional upfit switches on the headliner, while extended sideview mirror arms provide the driver with greater visibility. Chevy says this latter improvement is “coming soon.”
Finally, there is new left-hand power take-off capability, providing upfitters with access to the PTO port from either side of the truck, while longer axle-to-end-of-frame options for the short wheelbase models enables utilization of longer upfit bodies and greater flexibility.
The Chevrolet Silverado MD pickups were introduced in 2018 at the NTEA Work Truck Show in Indianapolis as a replacement for the Chevrolet Kodiak, which was discontinued in 2009. The medium-duty Silverado first went on sale for the 2019 model year, and is produced as part of a joint venture between GM and Navistar International, with final production performed by Navistar in Springfield, Ohio.
Motivation for the Chevrolet Silverado MD trucks is sourced from the turbodiesel 6.6L L5D V8 Duramax, which produces 350 horsepower and 700 pound-feet of torque. The L5D is manufactured at the GM Duramax plant in Moraine, Ohio.
