Chevy Ends Silverado MD Deal Built With International

Chevy Silverado – General Motors will end production of its Silverado MD medium-duty trucks after its partnership with International wraps up, with plant changes in Ohio.

Chevy’s medium-duty Silverado is headed for the production line’s last turn, and the shift reshapes a niche of the commercial-truck market where partnerships used to drive capacity.

General Motors will discontinue the Silverado 4500 HD. 5500 HD. and 6500 HD—medium-duty Class 6 trucks built on a shared platform and manufacturing setup with International’s CV Series.. The change will take effect with production ending September 30. 2026 for the Silverado MD models. according to reporting carried by TFL Truck.

The endgame traces back to GM’s decision not to renew its contract with International. a deal originally signed in 2015—before International was known as it is today—when it was Navistar.. That arrangement supported joint development and manufacturing of the International CV and the Chevrolet Silverado MD trucks. but the reported decision not to extend it now forces the program toward closure.

International’s own vehicle lineup is also shrinking in parallel.. The report said International will discontinue its CV Series as well, with production ending September 10.. That timing matters because it leaves limited room for continuing a shared manufacturing footprint that had supported both brands’ Class 6 offerings.

One of the most immediate knock-on effects is happening at the manufacturing site in Springfield, Ohio.. International has reportedly agreed to sell the Springfield plant to Canadian defense contractor Roshel effective March 30, 2026.. That sale covers both the assembly plant and a co-located specialty truck center. creating a major ownership change for a facility that has long been tied to truck production.

Why GM chose not to re-up its International contract is not pinned to a single cause. but the reporting points to market pressure on medium-duty sales and overlap with competing models.. TFL Truck cited a decline in demand for the Chevy-badged trucks. noting that Chevrolet sold 1. 273 units in the first quarter of the year.. That would represent a drop of 37.4% compared with the first quarter of 2025.

Competition is also part of the picture. Ford reportedly sold 2,331 F-650 and F-750 trucks during the first quarter of 2026. In addition, International’s MV Series is available in the same Class 6 configuration as the CV Series, which sources say creates overlap within the medium-duty segment.

The Silverado MD program itself has been a specialized offering built around a specific mechanical package.. Unveiled in 2018 at the Work Truck Show in Indianapolis. the Silverado MD models use a Duramax 6.6-liter turbodiesel V8 tuned to produce 350 horsepower and 750 pound-feet of torque.. Power is sent through an Allison six-speed automatic transmission, maintaining the heavy-duty drivability that commercial customers typically expect.

Configuration options add to the program’s “work truck” profile.. Four-wheel drive is available, and customers can choose between regular cab and crew cab setups.. Wheelbases vary widely—from 165 inches to 243 inches—while gross vehicle weight ratings run from 14. 001 to 16. 500 pounds on the 4500 HD. from 17. 500 to 19. 500 pounds on the 5500 HD. and from 21. 000 to 23. 500 pounds on the 6500 HD.

For many commercial customers. what happens next is less about brand logos and more about what changes in production. supply. and long-term support.. Transport Topics reported that much of the Ohio plant’s capacity was dedicated to the Chevy-badged trucks. which is part of why International’s sale decision matters: it underscores that the facility’s commercial output was closely tied to the Silverado MD and CV Series joint arrangement.

The Springfield site has a long industrial history.. Reporting said the company has been building trucks and buses at the plant since 1961. and the factory previously survived cutbacks linked to International Harvester’s reorganization in 1982. which sidelined a Fort Wayne. Indiana. plant.. The Roshel transaction is described as giving the Ohio facility a new reprieve. with the Canadian company buying both the assembly plant and specialty truck center and taking over a footprint totaling about two million square feet across roughly 500 acres.

Even as GM exits this particular large-chassis-cab corner of the market. it is not walking away entirely from medium- and commercial-duty trucks.. The company still has a joint-venture commercial truck in its catalog: the Isuzu-derived LCF (Low Cab Forward) series.. The report said GM is expected to keep selling the LCF in Class 4, 5, and 6 configurations for the 2027 model year.

For U.S.. buyers who rely on Class 6 trucks. the departure from the mega chassis cab segment could also shift dealer inventory strategies and fleet procurement plans.. With Ford still active in the segment and GM stepping back from the joint-venture chassis-cab space. fleets may face a more limited set of paths for ordering specific configurations. especially where production timing and manufacturing capacity become the deciding factors.

Meanwhile. the sequence of dates—International CV production ending September 10. Chevy Silverado MD production ending September 30. 2026. and the Ohio plant changing hands March 30. 2026—sets up a compressed transition window.. In practical terms. it highlights how quickly commercial manufacturing partnerships can unwind when contract renewals. demand trends. and facility economics no longer align.
