    Check Out the 2021 Chevrolet Silverado 2500 HD in Harlingen, TX


    As much as we love the Chevy Silverado 1500, there are some jobs and hobbies that just call for more power. The 2021 Chevy Silverado 2500 HD delivers, arriving at Gillman Chevrolet Harlingen with a roster of standard and optional features that make it a smart buy no matter why you need a heavy-duty new Chevy truck.

    2021 Chevrolet Silverado 2500 HD Performance

    The engine you choose for your 2021 Chevy Silverado 2500 will depend on your needs and priorities. For a daily drive with better efficiency, we suggest the 401 horsepower V8 engine. But if you want the full 18,510 pound towing capacity, you’ll want the 445 horsepower and 910 lb.-ft. of torque offered by the 6.6L Duramax turbodiesel engine.

    2021 Chevrolet Silverado 2500 HD Special & Safety Features

    There’s a Chevy Silverado 2500 HD trim for everyone. These range from the back-to-basics WT (work truck) trim to the reinforced suspension, skid plates, Rancho shocks, and all-terrain tires of the Z71 Off-Road package, or the tech and luxury-heavy High Country trim. Your Chevy dealer serving McAllen, TX will help you match the features you want, from heated seats to productivity enhancements, or the versatility afforded by Android Auto™, and Apple CarPlay®). Still want more? Explore our selection of Chevy truck accessories for even more choices.


    The 2021 Chevy Silverado 2500 HD doesn’t just rely on size for safety. The rear-view camera offers fifteen different views and can be complemented with the class-exclusive Transparent Trailer that uses a pair of cameras to “see-through” your trailer. Some driver-assist features, like AEB and blind-spot monitoring, can be optioned into the lower trims, or come as standard equipment further up the lineup.

    Buy or Lease a 2021 Chevrolet Silverado 2500 HD?
