While the smaller brother hit the roads in the year before, 2020 marked the start of the HD lineup, and more specifically, the 3500. When this generation debuted, it brought a monster towing capacity. According to Motor Trend, this behemoth can tow up to 35,500 pounds when properly equipped.
If you're not looking for the most capable option, then you'll be happy to know that the least it can tow is 20,000 pounds with the easiest setup. This is thanks to the 6.6L V8 diesel engine that is able to make 445 horsepower and 910 lb-ft of torque. If you don't want a diesel engine, then you can look for the 6.6L V8 gas engine. This engine outputs 401 horsepower and 465 lb-ft of torque.
While the capability is important, so are features, and the Silverado 3500 HD isn't lacking in that department either. For the interior tech, you'll find that it comes with either a 7-inch screen or an 8-inch screen, depending on the trim. One thing that isn't trim-dependent is the phone connectivity. This makes it easy to connect to your favorite playlist or make important phone calls without needing to take your hands off the wheel. Giving this model a passive safety layer.
If you want the most out of the tech, then you can look for a model that is equipped with a seven-speaker Bose audio system, additional power points, SiriusXM satellite radio, a Wi-Fi hotspot, and wireless charging. This makes it so that even though this is a workhorse, it still comes with some creature comforts.
When sitting behind the wheel, or anywhere else for that matter, you'll be able to find extra comfort thanks to heated and ventilated front seats, heated rear seats, and a heated steering wheel. After long days at the site or on the road, you can unwind a bit thanks to this. When operating the truck, if you're lucky, you can find a model that comes with a head-up display. This makes it so that you won't need to take your eyes off the road to check your speed.
Starting with the 2021 models, the 3500HD hit the gym a bit, and because of this, it came with a new, higher tow rating. When properly equipped, you'll now be able to tow 36,000 pounds as per Car and Driver. Able to tow 500 more pounds than the previous iteration. This makes it one of the baddest trucks on the market, able to do whatever you need it to, with ease.
Much like other models in the family, this year also brought some new tech that helped keep you safe when operating the Sierra 3500. This is the addition of a jackknife alert, where if the system detects any uneven angles, you'll know to help keep it under control. This also comes with a trailer length indicator, helping you when it comes to lane changes, making sure that you stay safe.
The last set of large changes came in 2024. This saw an overhaul to the LT, LTZ, and High Country trims. These now come with larger screens, with the digital gauge display now sitting at 12.3 inches, and the infotainment screen now sitting at 13.4 inches.
But besides this, the model hasn't seen many more changes, which isn't the worst. If you want the best model possible, it does make it a bit easier, as you won't have to look for the newest one on the market.
