The 2027 Chevrolet Silverado HD introduces an all-new Duramax 8.3L Turbo-Diesel V8 producing 555 hp and 1,230 lb-ft of torque. That torque figure is best-in-class and represents a substantial leap over the previous generation's diesel output. This page covers every major change, all six trims, and available inventory at ASA Auto Plaza serving Jackson, MN.
The headline change is the all-new Duramax 8.3L Turbo-Diesel V8, a completely redesigned engine that delivers 555 horsepower and 1,230 lb-ft of torque, both best-in-class figures. Chevrolet 2027 Silverado HD official page That engine, paired with an Allison 10-speed automatic transmission, pushes maximum available towing to 38,000 lbs, a number that resets expectations for what a production HD pickup can pull.
Beyond the diesel, Chevrolet made two firsts happen simultaneously on a heavy-duty truck. First-in-segment electric power steering replaces the hydraulic system, giving the Silverado HD rack-and-pinion precision, quieter operation, and reduced steering kickback on rough terrain. Second, the new eBoost electronic brake boost system, first-in-class for HD trucks, delivers smoother and more predictable stopping power under load, on long grades, and during repeated stops while towing.
The 6.6L gas V8 also receives enhancements for 2027, and it now features a standard oil level sensor with a Driver Information Center readout. Trail Boss availability expands to the Custom trim for the first time. The ZR2 gains access to a new Terrain Mode, unlocked specifically by the combination of electric power steering and eBoost, that did not exist on prior Silverado HD models.
The 2027 Silverado HD offers six trims, each built for a distinct buyer.
WT (Work Truck) is the no-nonsense foundation. It carries the full powertrain lineup and all first-in-class safety and steering hardware, making it the right choice for fleet buyers and contractors who want maximum capability without extra features.
Custom adds style-oriented exterior content over the WT. For 2027, Custom is the first trim to offer the Trail Boss off-road package, which is a meaningful upgrade for buyers who want off-road capability at an accessible entry point in the lineup.
LT sits at the center of the lineup with a balance of comfort features and full towing capability. It suits buyers who haul or tow regularly and want a more finished interior without stepping into premium territory.
LTZ brings premium materials, additional technology content, and a more refined cabin. It pairs the full 38,000-lb towing capability with features more commonly associated with luxury trucks.
ZR2 is the dedicated off-road performer. It rides on Multimatic DSSV dampers, wears 35-inch MT tires, uses a rear e-locker, and sits on aluminum skid plates. The 1.5-inch factory lift and Terrain Mode, enabled by electric power steering and eBoost, make the ZR2 the most capable off-road HD Chevrolet has ever built.
High Country is the top-tier model and focuses on luxury appointments, premium interior materials, and a refined driving character. It delivers the same best-in-class towing numbers wrapped in the most polished cabin in the lineup.
Two engines are available for 2027.
The standard engine is the enhanced 6.6L gas V8. It is built in Tonawanda, NY, carries its own updated output figures, and produces up to 6,990 lbs of maximum available payload. It pairs with a 10-speed automatic transmission.
The available engine is the all-new Duramax 8.3L Turbo-Diesel V8. Built in Brookville, OH, it produces 555 hp and 1,230 lb-ft of torque. It pairs with the Allison 10-speed automatic, which includes a diesel exhaust brake and grade-braking strategies that reduce heat and wear on the friction brakes during long descents. Maximum available towing with the diesel reaches 38,000 lbs. Maximum available payload with the gas engine reaches 6,990 lbs.
The electric power steering system is tuned specifically for towing loads. Tow/Haul Mode increases steering damping for better trailer stability at speed, and the eBoost system delivers more consistent brake feel across repeated stops, a real advantage on rural Minnesota routes where long grades and highway hauling are part of a typical workday.
Allison transmission specifications
The 2027 Silverado HD measures 235.5 inches in overall length and provides a 6.67-foot bed. The Multi-Flex tailgate carries over and gives the bed multiple load configurations for different cargo types. The Durabed steel bed is designed for long-term durability in work environments.
Inside, the cabin reflects the trim level chosen. The High Country delivers two-tone leather seating with contrasting stitching and perforated surfaces. The LTZ offers premium materials with a more work-friendly layout. The WT and Custom trims prioritize durability and function over refinement.
Rear passenger space is generous across all crew cab configurations, with rear climate vents available on upper trims. The 12.3-inch Driver Information Center sits in the instrument cluster and provides real-time vehicle data including, on the gas V8, the new standard oil level readout.
A 13.4-inch touchscreen anchors the center stack across the lineup. The 12.3-inch Driver Information Center provides a secondary data display for the driver. Google Built-in is available, and Google Gemini serves as an available AI assistant for voice commands, navigation, and connected features.
OnStar Basics is standard for 8 years and includes remote commands, Automatic Crash Response, built-in voice assistance, real-time navigation, and access to audio streaming apps. That 8-year window is a long baseline of connected safety coverage included with the truck.
Up to 14 available camera views support hitching, reversing, lane changes, and trailer monitoring. The in-vehicle trailering app and available Trailer Side Blind Zone Alert round out the trailering technology suite for buyers who spend significant time with a fifth-wheel or gooseneck attached.
The 2027 Silverado HD ships with a broad standard safety suite. Forward Collision Alert, Automatic Emergency Braking, Front Pedestrian Braking, Lane Keep Assist with Lane Departure Warning, Following Distance Indicator, and IntelliBeam high beam assist are all standard across the lineup. Adaptive Cruise Control is also standard.
The two first-in-class systems, eBoost and electric power steering, contribute directly to active safety. The eBoost system provides smoother, faster brake response and improved cooling during repeated heavy stops. Electric power steering reduces kickback on rough surfaces and improves precision during trailer maneuvering.
On ZR2, Terrain Mode, enabled by the electric power steering and eBoost combination, adds a new layer of control on dirt, sand, and rock that was unavailable on any prior Silverado HD.
The prior Silverado HD was already a capable work truck. The 2027 model is a different proposition in three specific ways. The new 8.3L diesel adds substantial torque and towing capacity over its predecessor. Electric power steering and eBoost are not incremental refinements; they represent a full system change in how the truck steers and stops. And Terrain Mode on the ZR2 is a capability that simply did not exist before.
Buyers who tow heavy loads regularly, whether in Jackson, MN or anywhere across southwest Minnesota, will notice the difference the moment they pull a loaded trailer onto a highway grade. The 38,000-lb tow rating opens doors for gooseneck trailers, heavy equipment haulers, and fifth-wheel configurations that the prior generation could not match.
Buyers who want an off-road HD truck have a more capable ZR2 than any previous generation offered. Buyers who want work-truck value can now get Trail Boss capability starting on the Custom trim. The 2027 Silverado HD is a broader truck than its predecessor in almost every direction.
The 2027 Silverado HD is expected to arrive later in 2026. ASA Auto Plaza in Jackson, MN is the local destination for Chevrolet HD trucks serving buyers throughout southwest Minnesota. Check current inventory, register for updates on 2027 availability, or bring in your current truck for a trade-in appraisal while demand is high.
Maximum available towing reaches 38,000 lbs with the all-new Duramax 8.3L Turbo-Diesel V8 and the Allison 10-speed automatic transmission. The gas V8 carries a separate towing rating of up to 19,000 lbs.
Two engines are available: the enhanced 6.6L gas V8 and the all-new Duramax 8.3L Turbo-Diesel V8. The diesel produces 555 hp and 1,230 lb-ft of torque, both best-in-class figures for the segment.
eBoost is an electronic brake boost system that delivers smoother and faster brake response with improved cooling during repeated heavy stops. It is a first-in-class system for HD trucks and contributes to more predictable braking under load, especially on long grades.
Yes. The 2027 Silverado HD is the first heavy-duty truck in its class to feature electric power steering. The electrically assisted rack-and-pinion system reduces steering kickback off-road, operates quietly without hydraulic noise, and enables Terrain Mode on ZR2.
Six trims are offered: WT, Custom, LT, LTZ, ZR2, and High Country. Trail Boss is a package now available starting on the Custom trim, which is new for 2027.
The 2027 ZR2 adds Terrain Mode, a new drive mode unlocked by the combination of electric power steering and eBoost. It also features larger Multimatic DSSV dampers, a rear e-locker, 35-inch MT tires, aluminum skid plates, and a 1.5-inch factory lift.
