2027 Silverado 2500HD vs. Ram 2500 vs. Ford F-250: Which HD Truck Works Hardest?

Three-quarter-ton trucks get bought on numbers. For 2027, all three of the big players moved theirs. Chevrolet replaced the Duramax with a clean-sheet 8.3L V8. Ford retuned the Godzilla gas engine. Ram brought the Cummins High-Output to a trim that never had it.

If you run a crew out of Dallas, Plano or Carrollton, the question is simple. Which of those changes actually shows up on your job site?

Here is the short version. The 2027 Chevrolet Silverado 2500HD leads all three on torque, in diesel and in gas. It is also the only truck here moving to electric power steering. That is the difference you feel backing a gooseneck into a tight lot at six in the morning.

At a Glance: Who Leads Each Category

The Diesel Engines: Where the 2027 Race Was Decided

Chevrolet’s new 8.3L Duramax Turbo-Diesel V8 is the brand’s first clean-sheet heavy-duty diesel designed and built in-house. It replaces the 6.6L as the only diesel in the lineup. GM rates it at 555 horsepower and 1,230 lb-ft, best-in-class on both counts, paired to the Allison 10-speed automatic.

The gap to Ford is narrow: 55 horsepower and 30 lb-ft against the Power Stroke. The gap to Ram is wide: 125 horsepower and 155 lb-ft against the Cummins High-Output. Ram’s eight-speed is also the only transmission here with two fewer gears to work with when a loaded trailer hits a grade.

The Gas V8s: Torque Is the Number That Matters

Most work-truck buyers who skip the diesel are doing it on upfront cost. That is where the gas comparison earns its keep. Chevrolet enhanced the 6.6L gas V8 for 2027 to 412 horsepower and 472 lb-ft. GM calls that best-in-class standard torque among 2027 heavy-duty gas engines.

Ford takes horsepower by eight. Chevrolet takes torque by 27 lb-ft over Ford and 43 lb-ft over Ram. Torque at low rpm is what gets a loaded trailer moving. It is also worth noting that Ford needs 7.3 liters to get there. Chevrolet does it with 6.6.

Towing and Payload for Texas Work Crews

Chevrolet rates the 2027 Silverado HD lineup at up to 20,000 lbs conventional and 38,000 lbs gooseneck when properly equipped. Gross combined weight rating runs up to 46,500 lbs. You can see how Chevrolet frames the matchup on its own Silverado HD vs. Ford Super Duty and Silverado HD vs. Ram HD pages.

One caveat matters here. Those are lineup maximums that include the 3500HD. Chevrolet has not yet released per-configuration 2500HD ratings, which arrive with the trucks this winter. We will have exact numbers as soon as they land. Reach out to our truck team and we will pull them for your spec.

Here is what Ram and Ford publish for their three-quarter-ton trucks today.

Maximum towing and payload capacity figures are based on properly equipped vehicles and vary by configuration. Do not exceed any weight rating. See your owner’s manual and the vehicle’s door-jamb label for specific capacities.

Two things are worth knowing before you compare those columns to anything you read elsewhere. Ram publishes its 2027 figures as preliminary. And Ford’s widely advertised 40,000-lb towing and 7,900-lb payload are F-450 and F-350 dually ratings, not F-250 ratings. If you are shopping three-quarter-ton, the numbers in the table above are the ones that apply to you.

Ram does take the gas payload crown at 4,580 lbs. A new Payload Upgrade Package raises GVWR above 10,000 lbs on most HEMI-equipped 2500s. Credit where it is due.

Steering and Braking: The 2027 Silverado’s Clear Advantage

This is the change nobody is talking about, and every crew foreman will notice it. For 2027, Chevrolet replaced the Silverado HD’s hydraulic steering with a segment-first rack-and-pinion electric power steering system. GM says it delivers roughly 30 percent more steering output than the gear it replaces. A new electronic brake-boost architecture comes with it.

The electric system works independently of engine speed. That means steering assist does not fade when you are creeping a loaded trailer at idle. Ford’s 2027 Super Duty still uses power hydraulic steering. For a crew that spends more time maneuvering in a yard than on the highway, that is a daily-use difference rather than a spec-sheet one.

On the trailering side, Chevrolet offers up to eight cameras with as many as 14 views. These include hitch view, transparent trailer view and bed view. Add Trailer Side Blind Zone Alert and an in-vehicle trailering app for custom trailer profiles and pre-departure checklists. Ford counters with Pro Trailer Hitch Assist, Pro Trailer Backup Assist, onboard scales with Smart Hitch, and BLIS with trailer coverage. Both systems are genuinely useful. Neither replaces a spotter on a blind-side back.

Driver-assistance and advanced safety systems are supplemental aids and are not substitutes for safe and attentive driving. Availability, operation, and effectiveness vary by trim and equipment and depend on factors including road, weather, traffic, and vehicle condition. Always keep your hands on the wheel and your eyes on the road. See your owner’s manual for system limitations and details.

Cab, Bed and Crew Capacity

All three seat up to six in crew-cab form. For 2027, Ford publishes a 6.75-foot box at 81.9 inches and an 8-foot box at 98.1 inches, with the long box measuring 78.5 cubic feet. Ram’s crew cab pairs with a 6-foot-4-inch bed in its short-box configuration.

Chevrolet publishes 83.5 cubic feet for the current Silverado HD Durabed, which it calls more cargo volume than any competitor. GM’s 2027 announcement covered powertrain, steering, braking and chassis, so ask us to confirm bed specifications against the 2027 order guide before you spec a truck around them.

On the current Silverado HD, Chevrolet also fits twelve standard tie-downs rated at 500 lbs per corner and integrated BedSteps. The available Multi-Flex Tailgate adds six configurations, including a full-width step rated to 375 lbs. If your crew loads and unloads a dozen times a day, those add up.

Not sure whether a standard or long box fits your work? Our Chevrolet bed sizes guide breaks down every configuration.

Trim Lineups

Ram offers the broadest ladder and Ford the narrowest. Chevrolet’s six-trim structure runs from the work-focused WT to the off-road ZR2 with its Multimatic DSSV dampers and 35-inch tires.

Still deciding whether a three-quarter-ton is the right size at all? Our Silverado 1500 vs. 2500 vs. 3500 comparison walks through where each one fits. Crews hauling above 2500HD limits should look at the Silverado 3500 HD.

A Note on Fuel Economy

Heavy-duty pickups above 8,500 lbs GVWR are not required to carry EPA fuel-economy ratings. None of these three publishes an EPA estimate, so there is no official number to compare.
