In resent years, the Chevy Silverado 3500 was criticized for trailing its rivals in terms of towing power, pulling capability, and cab space. However, with the launch of the all-new fourth-generation Silverado 2500HD and 3500HD for 2020, Chevrolet took the lead in all of these critical areas. The HD pickup trucks became bigger in every dimension, and they no longer look like oversized versions of the half-ton Silverado. The only sheetmetal part shared with the 1500 is the roof. More importantly, thanks to an improved ladder frame, beefed-up driveline and suspension parts, and stronger powertrains, the Silverado 3500 can now tow bigger loads than any other truck in its class. In its dually form equipped with a diesel engine and a gooseneck hitch, it can pull up to 35,500 pounds. Whether you are looking to upgrade your big rig to put it to work or use it for hard play, we have the right 2020 Chevy Silverado 3500 accessories in our catalog.

Motive power comes from an all-new 6.6-liter gasoline V8 or a carryover 6.6-liter Duramax turbodiesel. The gas engine replaces the aging 6.0-liter Vortec V8 that has been around for almost 20 years. The new unit is tuned to develop 401 hp and class-leading 464 lb-ft of torque, which is a significant increase over the old engine’s output. A 6-speed automatic transmission continues getting power to the wheels. The optional diesel still makes 445 hp and 910 lb-ft of torque, but it’s now paired to an all-new Allison 10-speed automatic. It makes more torque available in lower gears, improving the overall dynamics and shifting performance when towing. Trailering is made easier thanks to a few notable technologies that Chevy makes available for its 2020 heavy-duty pickups. The optional Advanced Trailering System offers the camera-based Transparent Trailer feature that allows the driver to see the tailgaters. Thanks to the myChevrolet app that integrates with the intelligent trailer control system, the driver can monitor and operate some of the functions like HVAC and generator.

With the gas engine, RWD, and dually wheels on the rear axle, the 2020 Silverado 3500HD can haul up to 7,442 pounds in its cargo box and cab. Heavy-duty models feature a new DuraBed box with more cargo volume than other trucks in this class and plenty of practical features. These include corner steps, tie-down rings, bed lighting, and 120-volt outlet for powering various accessories. If you want to turn your truck into a more functional tool for commercial or personal-use needs, here you’ll find all 2020 Chevy Silverado 3500 parts and accessories you need to make your job easier.

Paid extra for the emblem and it was absolutely the right call. The embroidery is well done and truly adds a nice touch. Hope there won’t be any fading or issues with the mats anytime soon.
