Chevrolet Work Trucks & Medium Duty Chassis for Sale

Lynch Truck Center is a Chevrolet Business Elite dealer, and work trucks are the part of the lineup we move most. That covers Silverado 2500HD and 3500HD pickups for trades and contractors, the medium duty 4500HD through 6500HD for dump, box, and landscape work, and Express vans and cutaways for delivery routes. Most of what leaves our lot has a body on it that we mounted here in Waterford. Below is how the weight classes break down and what we can build on each one.

From dump trucks and box trucks to utility bodies and flatbeds, Chevrolet medium-duty chassis provide a dependable foundation for demanding commercial operations. These trucks are commonly used by contractors, municipalities, delivery fleets, construction companies, and service providers throughout multiple industries.

Which Weight Class Fits Your Load

Start with the heaviest thing you haul on a normal week, not the once-a-year job. A Silverado 2500HD or 3500HD covers most trade work, tool bodies, and light dump duty. The 4500HD picks up where the pickups run out at 14,001 to 16,500 pounds GVWR. The 5500HD runs 17,500 to 19,500 pounds and is the most popular of the three because it fits so many bodies. The 6500HD goes up to 23,500 pounds GVWR and 37,500 pounds GCWR when the load gets serious. Buy a class too small and you cook brakes and springs. Buy a class too big and you pay for capacity that never leaves the yard.

Chevrolet 4500HD, 5500HD, and 6500HD Specs

The three existing spec blocks stay exactly as written. Only the heading above changes, and the separate "Chevrolet 4500HD," "Chevrolet 5500HD," and "Chevrolet 6500HD" subheadings drop to H3 under this H2 so the brand name is not repeated in four headers

GVWR: 14,001–16,500 lbs.
Available in Regular Cab and Crew Cab

Common Chevrolet Medium Duty Applications

Chevrolet medium-duty trucks are commonly configured as:

Box trucks
Dump trucks
Stake beds
Flatbeds
Utility trucks
Service body trucks
Landscape trucks
Glass rack trucks
Refrigerated delivery trucks

The Silverado medium-duty lineup is specifically engineered for vocational flexibility, making it ideal for fleets and businesses requiring customized work truck solutions.

Silverado 2500HD and 3500HD for Trades and Contractors

The three-quarter and one-ton Silverados are the trucks that show up on most job sites, and they carry more of our volume than the medium duties do. A 2500HD with a utility body handles electrical, plumbing, and HVAC work without turning into more truck than a crew needs. A 3500HD, especially a dually, is where landscape dumps, flatbeds, and heavier service bodies start to make sense. If you are running a mixed crew and want every truck to feel the same to drive, this is usually where standardizing pays off.

Express Vans and Cutaways for Delivery Routes

Not every job needs an open bed. The Express cargo van keeps tools and product locked up and out of the weather, and it parks where a work truck cannot. The Express cutaway takes it further by leaving the back open for a body, which is how most of ours go out the door: KUV-style service bodies for mobile trades, or box bodies for delivery. If you are running out of room in a cargo van but do not want to jump a whole truck class, a cutaway is usually the answer.

Duramax Power and Allison Automatics

The medium duty line pairs the Duramax 6.6L turbo-diesel V8 with an Allison automatic, and that combination is a large part of why these trucks hold up in fleet service. The Allison handles the constant heavy launches and stop-and-go work that wear out lighter transmissions, and the low-end torque means a loaded truck pulls a grade without straining. Gas is available on the low cab forward models when the routes are short and the idling is heavy. Tell us the route profile and we will tell you which one we would put you in.

PTO and Vocational Equipment

If the body needs to run something, the truck has to be spec'd for it before the build starts. Power take-off availability on the 5500HD drives dump hoists, cranes, liftgates, and similar equipment off the transmission. Retrofitting that after the fact is expensive and sometimes not possible, so it belongs in the first conversation, not the last one. Bring us the body you have in mind and we will tell you what the chassis needs.
