Refreshed 2024 Silverado 3500HD Dually Work Truck Spied Testing

The Chevy Silverado HD will receive a major model refresh for the 2024 model year, introducing a wealth of updates and changes for the heavy-duty pickup nameplate. Now, GM Authority has caught this 2024 Silverado 3500HD prototype testing on public roads, giving us an early look at what’s in store.

This particular 2024 Chevy Silverado 3500HD prototype is done up in the Crew Cab / Long Bed body style, with Dual Rear Wheels, otherwise known as a Dually or DRW. The truck is covered in heavy camouflage, obscuring the revised styling up front and in the rear. Nevertheless, there are a few details we can pick out, such as the broad horizontal slats used for the front grille, as well as revisions for the forward-facing lighting.

Moving to the sides, we see black door handles and black window trim, thus suggesting that this particular 2024 Silverado 3500HD prototype is the likely the base Work Truck trim level. The truck is also obviously towing a trailer via a hitch, with what looks to be a weight plate on the trailer itself.

The rear end is also obscured, covering up what is expected to be a rear styling update. The camo covers were added to the rear fenders, the tailgate, and the taillights.

In addition to revised exterior styling, the refreshed 2024 Silverado HD will also feature a completely revamped interior that will take after the refreshed 2022 Silverado 1500 light duty pickup.

What’s more, the 2024 Silverado HD should deliver a relatively solid powertrain update. As GM Authority covered previously, refreshed 2024 Silverado HD and 2024 Sierra HD models equipped with the Duramax diesel engine are rumored to dole out nearly 1,100 pound-feet of torque and more than 500 horsepower. For those keeping score at home, that’s a major boost over the current tune for the 6.6L V8 L5P turbodiesel Duramax, which is rated at 910 pound-feet of torque and 445 horsepower.

Finally, the refreshed 2024 Silverado HD will introduce a new Silverado HD ZR2 off-roader model for vehicles equipped with a single-rear wheel layout. As GM Authority was the first to report, the new Silverado HD ZR2 is expected to be equipped with front and rear locking diffs and new specialty dampers, plus aggressive 35-inch Goodyear Wrangler Territory MT tires.

As a reminder, the Silverado HD was originally slated for a refresh with the 2023 model year, but due to complications stemming from the COVID-19 pandemic and ongoing microchip shortage, the refresh was delayed a year.

  1. Will be a beast. Hopefully they dont do a tiered spec like Ram does with the HO Cummins.

  2. Let’s just hope it looks better. The current truck is……you know what, forget it🤦‍♂️

    1. I like this game.

      “The current truck is”… selling like hotcakes.

      Despite all the noise from sofa CEOs, the current truck is a commercial success and has brought more new-to-Chevy customers than the two prior generations of the Silverado HD have. GM literally can’t make enough of the current truck, which is the reason that the reborn Oshawa plant will exclusively make Silverado HD (as opposed to both the Silverado HD and Sierra HD).

      1. Not sure what your comment has to do with anything I said. Everything is selling like hotcakes in the current market. What earth shattering knowledge are you gonna drop on me next?

        1. That the “ugly” truck outsold ford last year and will do so again this year?

      2. Alex,
        While an all around awesome truck, the 2020-2023 Chevy HD’s leave a bit to be desired in the front end treatment sir. The High Country and funny enough the Custom trim’s look the leat unappealing to me.

        And yes, I may trade my handsome 2019 black Sport Appearance Package 3500 dually on a 2023 due to it being worth more than I paid for it, but that does not mean I find the new truck better looking, just more capable with a larger, nicer interior, box side steps, power folding tailgate and excellent 10 speed Automatic.

        I was hoping the MCR was going to hit in 23, as I am looking forward to seeing what Chevy did with the front end treatment.

  3. I’m hoping they actually push the envelope on technology, not just bolt on a bigger turbocharger. I’ve been waiting for someone to add ceramic piston coatings to a production engine. Testing in the 90’s returned 10% better low end power and lower emissions. Doing that means they could leave most of the rest of the system unchanged and proven. Race teams already use the tech for heat control

  4. current truck is selling , simple cause there arent enough trucks to go around. Ride the interstates , The Ram 3500 & 4500 dominate with hot shots , car carriers , large enclosed trailers, ect, Ford is right up there with them. All you GM guys wait year after year for GM to dangle the carrot of what might come, and the last 3 years provide stupid crap like paint colors, and black out packages , yet the duramax is from the last decade, and now the fake allison. there is NO wow factor in GM trucks. GM talking about 505 HP , WHATEVER You hopeful fools. My 2022 Freightliner has a DD13 505 HP with 1850 Torque , how the hell do you get that out of a 3500 dually. All 3 play with HP and Torque. My Ram 3500 Aisin with 1075 pulls the same as My older 950 Torque Cummins, The new Ford has a 1050 , and its fast like a raped ape. GM is always late to the game because the bean counters play games, I bet everyone will love the new 2024 HD with the car like dash, Its a total shame whats happened to GM.

    1. Then get off this site. GM dominates in the agriculture and vocational market, largely do to the fact that fords keep blowing up their diesels and The Cummins is the only thing that is reliable about Ram. GM’s real problem with the HD market has been that their production capacity was half that of fords till last year. Getting 500hp out of a freight liner is chump change. I can get 500 HP out of a geo metro (LS fest anyone?) a tractor isn’t an HD truck, so get off your high horse. A 3500 dually will pull its max load up a hill without creating a mile line behind it like your freightliner will, and also can haul, not just tow, and can go off road, because it’s actually a truck, not a tractor. Make sure you compare apples to apples.

      If we’re talking numbers, the GM HD’s are vest in class by far. GM’s are more economical, longer lasting and fuel efficient than RAM or Fodz. That’s proven data. Also, fodz max tow figure is rigged. Your need to get the special rear end and packages to be set up to tow a measly 100 more lbs. GM does their max strait from the factory. 1 rear end per engine. Those numbers are where it counts. Not just chasing headlines like having 1050 ftlbs of torque and not being able to use it because your transmission can’t handle it.

      1. Steven,
        I have a 2019 Denali 2500 Duramax, and No its not as great of a puller, sorry. My denali has 4 open recalls currently, and then a new letter last month stating I now have up to 150K warantee on fuel injectors cause there defective and if they fail they will cover , they are doing this because the government complaints . I own every truck I talked about above. A Freightliner M2 sport chassis is not a semi (you know it all ) . The Ram out pulls them all on torque hands down. The Ford is comfortable , fast, pulls well, great cameras, michelin tires, many colors in paint , 5 different interiors , more torque . according to you GM guys the 10 speed transmission in the Ford is the same as GM’s so how the hell do you say it cant handle the torque. GM is 5 years behind and you know it. thin seats, cheap plastic , blown plastic interiors, little tiny dash knobs , and I’m sure you love the new car like dash. By the way GM is still 2 years out on HD refresh

        1. 2 things, freighliner sport chassis is still a tractor. Doesn’t matter how you dress up a pig, it’s a tractor that isn’t designed to haul or go off road. It’s a fancy RV tow rig. Weight distribution is off compared to a pickup, and is a pure tow vehicle. Compare apples to apples. FYI, do your research. The ford and GM transmissions are co-developed, but physically different. Fords 10r80 and GM’s 10l90 have slight changes in gear ratios and torque capacity as GM updated theirs for the LT5 in the vette. The ford 10r140 and Allison 10l1000 are extremely different. GM did send the transmission over to Allison which led to the deletion of the 1 way clutch and a stronger casing. Gear ratios were reoptimized and Allison added their proprietary software transmission programming. It’s not just an Allison stamped transmission. FYI, ZF doesn’t make Rams transmissions just because it’s their design. Are we going to call Rams transmissions not a ZF cause stellantis makes them in house?

  5. Steven the GEO MEtro owner above wishes he could afford a Freightliner Sport chassis, Talk about dam nice pick up trucks ,

  6. I wonder if you could afford a pig talking about your Geo Metro. I own them all brother , 2022 Ford, 2021Ram, 2019 Denali , 22 Freightliner, I can tell you the pros and cons of all. your talking off road so much, 89% never go off road , even GM and Ford say that. My freightliner has a payload of 8900 and a GVW of 33000, and a tow rating over 40000. the duramax lags if you have over 12K lbs , The Ram with AISIN Trans HO will yank your Duramax down the highway sideways, you hook it on the back and its going with you. You talk about economy with GM, Who the piss cares, you buy the truck to pull, stick you fuel sipping crap. If you can’t afford Diesel go get a chevy bolt or dust off you Geo. O by the way on that Freightliner towing slow up a hill, bring it on brother . I came thru the Gorge in NC two weeks ago with my 5th wheel, a New Horizions Majestic that weighs 28k and the truck weighs 16K , come thru the Gorge at 68 miles an hour while the truckers were running 30 – 35 up hill.
    GM use to be great m, they have failed the consumer, peroid. Let go Brandon

  7. Let’s hope that GM finally installs air ride suspension for the HD trucks as Ram has done for years.
