Chevrolet’s biggest Silverado work trucks have reached the end of the line just as commercial fleets are entering another buying cycle. Production of the Silverado 4500 HD, 5500 HD and 6500 HD has concluded, closing the current Class 4–6 program that returned Chevrolet to conventional medium-duty trucks for the 2019 model year.
The move creates additional room for Ford and Ram, particularly among businesses buying pickup-style chassis cabs, but it does not mean GM is abandoning commercial trucks. Chevrolet still offers its Low Cab Forward range, while industry reporting points to a very different Class 4 and Class 5 Silverado successor derived more closely from future Silverado HD architecture. The important distinction is that GM has not formally announced that replacement or provided a launch date, leaving competitors with an opportunity while GM works out what comes next.
The Current Silverado MD Run Has Ended
The current Silverado medium-duty family was relatively young by commercial-truck standards. Chevrolet brought the 4500 HD, 5500 HD and 6500 HD into production for the 2019 model year, marking its return to the conventional medium-duty segment years after the old Kodiak disappeared. GM Authority reported on September 26, 2026, that Silverado MD production had concluded. GM’s manufacturing agreement with International Motors, which assembled the trucks in Springfield, Ohio, is scheduled to expire September 30.
The outgoing range covered a surprisingly broad part of the vocational market. Chevrolet offered regular- and crew-cab configurations, two- and four-wheel drive and wheelbases stretching from 165 to 243 inches. The 6500 HD could reach a gross vehicle weight rating of 23,500 pounds, while Chevrolet listed a maximum available gross combination weight rating of 37,500 pounds for the range. Sales had also been softening: U.S. Silverado MD volume fell from 10,319 units in 2024 to 8,341 in 2025, a decline of roughly 19 percent.
The Springfield Partnership Explains Why This Is Happening Now
The end of the truck is closely tied to the unusual partnership behind it. GM did not operate a dedicated Chevrolet plant for the Silverado 4500 through 6500. Instead, the trucks were assembled by what is now International Motors at its Springfield Assembly Plant in Ohio. The arrangement allowed Chevrolet to re-enter conventional medium duty without creating an entirely separate production operation, while International used related engineering and manufacturing resources for its own CV Series trucks.
That arrangement is now unwinding. International announced in March that Roshel had agreed to acquire the operating assets of the Springfield Assembly Plant and its Truck Specialty Center. International said the facility had been devoted almost exclusively to contract manufacturing under an agreement expiring September 30, 2026. Roshel plans to use the sprawling site—which International described as having more than two million square feet of space on roughly 500 acres—for commercial, special-purpose and armoured-vehicle manufacturing. International’s related CV Series is also ending, making the transition much larger than the disappearance of a Chevrolet badge alone.
Ford Has the Broadest Immediate Opening
Ford is particularly well placed because its commercial lineup already stretches through much of the territory occupied by the departing Chevrolet trucks. Ford’s 2027 chassis-cab configurator includes the F-450, F-550 and F-600, with starting prices for XL versions of roughly $56,000 to $59,000 in the United States. The F-600 is especially relevant because its available 22,000-pound GVWR pushes it into Class 6 territory, putting it closer to the work performed by the outgoing Silverado 6500.
Ford can then move customers farther up the ladder with the F-650 and F-750. For the 2026 lineup, Ford advertises maximum GVWR ratings reaching 37,000 pounds and gross combination ratings as high as 50,000 pounds, along with gasoline and diesel engine choices. That range matters to a landscaper who starts with a dump body, a municipality replacing utility trucks or a towing company that expects its equipment requirements to grow. Chevrolet’s departure removes one familiar conventional-cab alternative across several of those applications, giving Ford dealers a clearer opportunity to court displaced fleet customers.
Ram Has a Clean Shot at Class 4 and Class 5 Buyers
Ram does not cover the same upper-medium-duty territory as Ford, but the brand is positioned directly against an important portion of Chevrolet’s former business. Its 4500 and 5500 Chassis Cab models compete in Classes 4 and 5, the heart of the market for many service bodies, flatbeds, tow equipment, small dump bodies and other commercial conversions. Ram has already detailed its 2027 Chassis Cab lineup, with ordering scheduled to open in the fourth quarter of 2026.
The numbers make the overlap clear. Ram’s 4500 has been offered with a maximum GVWR of 16,500 pounds, while the 5500 reaches 19,500 pounds. For 2027, Ram says a properly configured 5500 with the 6.7-litre Cummins turbo-diesel can tow as much as 34,540 pounds. The diesel produces 360 horsepower and 800 pound-feet of torque. Ram also lists maximum payload of 12,370 pounds for certain gasoline-powered 5500 configurations. For a contractor who previously compared Silverado 4500 or 5500 chassis cabs against Ram, Chevrolet’s temporary absence makes that shopping list noticeably shorter.
The Silverado 6500 Leaves the Hardest Hole to Fill
The largest Silverado MD may be where Chevrolet’s departure becomes most noticeable. The outgoing 6500 HD carried GVWR ratings ranging from 21,000 to 23,500 pounds. Under commonly used federal weight classifications, Class 6 begins at 19,501 pounds and extends through 26,000 pounds. That means the 6500 occupied territory above the maximum 19,500-pound GVWR offered by the Ram 5500, which remains at the top of Class 5.
Ford has a more direct answer. Its F-600 can be configured to 22,000 pounds GVWR, overlapping part of the Silverado 6500’s old range, while the F-650 moves farther upward for businesses needing additional capacity. That gives Ford a structural advantage with customers who specifically want a conventional-cab truck above Class 5 without immediately moving into a much larger vehicle. Ram can still compete for many lighter vocational applications, but Chevrolet 6500 customers working near the truck’s maximum rating may have fewer genuinely comparable pickup-style options until GM either returns to Class 6 or provides more clarity about its future lineup.
Chevrolet Still Has Medium-Duty Trucks—Just in a Different Shape
GM’s move should not be confused with Chevrolet abandoning medium-duty commercial vehicles. Chevrolet continues to market its Low Cab Forward trucks, including heavier 6500 XD and 7500 XD configurations. The range extends to a maximum GVWR of 33,000 pounds, and Chevrolet says the platform can accommodate bodies as long as 30 feet. The diesel 6500 XD and 7500 XD use a 6.7-litre Cummins engine rated at 260 horsepower and 660 pound-feet of torque paired with an Allison transmission.
However, a Low Cab Forward truck is not necessarily a straightforward substitute for a Silverado 6500. Its cab-over layout puts the driver above the front axle and prioritizes maneuverability and usable frame space rather than the familiar long-hood arrangement of a pickup-derived or conventional truck. Chevrolet lists a minimum turning radius as tight as 31.5 feet for parts of the LCF range. That can be attractive for urban delivery or tightly packed job sites, but businesses that deliberately chose a Silverado-style cab, driving position and upfit configuration may still see a genuine hole in the lineup.
For Fleets, the Upfit Ecosystem Matters as Much as the Badge
Medium-duty trucks are rarely purchased as finished vehicles. A bare chassis may eventually become a utility truck, ambulance, tow truck, bucket truck, dump body, mobile service vehicle or refrigerated delivery unit. That makes dimensions, electrical connections, power take-off provisions and relationships with body manufacturers enormously important. The outgoing Silverado MD was designed from the start as a chassis cab intended to be customized by commercial upfitters rather than used like a conventional pickup.
Ford and Ram have spent years building their own systems around that reality. Ford Pro offers ship-through and drop-ship programs designed to move chassis between factories, upfitters and dealers, while its Vehicle Integration System 2.0 is intended to simplify communication between added commercial equipment and the vehicle. Ram promotes multiple cab-to-axle lengths, wheelbases and power take-off capability on its chassis cabs. For a fleet manager replacing dozens of near-identical service trucks, those details can be more consequential than grille design. Winning former Silverado customers will therefore involve more than simply having a truck with the correct GVWR.
GM’s Reported Replacement Takes a More Ford-and-Ram-Like Path
What comes next could look quite different from the truck that just disappeared. GM Authority, citing sources familiar with GM’s product plans, reported that a new Silverado medium-duty program is being developed for Classes 4 and 5. Instead of using another dedicated medium-duty architecture created with an outside commercial-truck manufacturer, the reported strategy starts with future Silverado HD underpinnings and strengthens them for heavier work.
According to that reporting, the proposed truck would use a heavier rear frame along with upgraded suspension components, wheels and tires. The approach would bring Chevrolet closer to the formula already used by Ford and Ram, which extend their heavy-duty pickup families upward into commercial chassis-cab applications. That is potentially a significant philosophical shift for GM. The outgoing Silverado MD was a purpose-built commercial collaboration with International; the reported successor would be much more closely related to GM’s own heavy-duty pickup family. GM itself has been considerably more cautious, saying only that it is evaluating future medium-duty portfolio options and will provide additional information when available.
A Pickup-Derived Design Could Change How the Next Chevy Feels
The architectural change could affect more than manufacturing. GM Authority’s sourcing indicates that the next Class 4 and Class 5 Silverado may sit lower and deliver a smoother ride than the outgoing medium-duty platform. The publication has also reported that traditional medium-duty features such as kingpin steering hardware and the driveshaft-mounted parking brake used by the current truck may not carry over if GM ultimately adopts the HD-derived design being developed.
For some customers, that could make the new truck feel more familiar. Contractors and small fleets increasingly move between heavy-duty pickups and chassis cabs, so a commercial truck sharing more of its basic architecture with an Silverado HD could reduce the jump between the two. For other buyers, however, specialized medium-duty hardware is part of the appeal of a dedicated vocational chassis. The engineering trade-off will become clearer only when GM releases specifications. At this point, reports describe a program under development rather than a finished truck, and details could still change before production.
The Real Opportunity for Ford and Ram Is the Gap Before GM Returns
The most important competitive factor may ultimately be time. Current Silverado MD production has ended, Ford already has its 2027 F-450, F-550 and F-600 chassis-cab range moving forward, and Ram has announced its 2027 4500 and 5500 lineup. GM, by contrast, has not announced a production date, specifications or even an official name for a conventional replacement. Commercial buyers generally cannot postpone equipment cycles indefinitely simply because a manufacturer intends to return to a segment.
Industry reporting suggests GM’s eventual answer could be more tightly integrated with a future Silverado HD generation, while a separate heavier Class 6 or Class 7 straight-rail truck has also reportedly been considered. Neither plan has been formally confirmed by GM. That leaves a potentially valuable window for Ford and Ram to put their trucks into fleets that previously bought Chevrolet. Once a work body, maintenance routine and replacement schedule are built around a different chassis, winning that customer back can become a much bigger task than simply launching another truck. GM may be reshaping its medium-duty strategy rather than abandoning it, but its rivals have an opening right now.
