Is a Chevy G30 a 1 ton?

Yes—the Chevy G30 is historically the 1-ton variant in GM's old G-series van lineup. Today, GM uses the Express/Savana naming, with the 3500 models serving as the modern counterpart to the former G30. This article explains what the G30 signified, how to verify the weight rating, and how the designation fits into GM’s current van lineup.


Understanding the G-series and the G30


The "G" in GM's G-series van family denoted a line of full-size, cargo- and passenger-oriented vans. The numbers—G10, G20, and G30—corresponded broadly to payload classes: roughly half-ton, three-quarter-ton, and one-ton capacity, respectively. The G30 was the heaviest-duty option in the lineup, typically used for cargo vans and box trucks, and was common on Chevrolet and GMC badged models from the late 1960s through the 1990s. In the mid‑1990s, GM shifted toward the Express/Savana branding, but many owners and enthusiasts still refer to these models by the old G-series designations.


Historical context


What follows is a concise guide to how GM labeled these heavy-duty vans and what that means for buyers and restorers today.



  • G10, G20, and G30 referred to roughly 1/2-ton, 3/4-ton, and 1-ton class vans, with the G30 representing the 1-ton variant.

  • GVWR (gross vehicle weight rating) on G30 vans generally sat in the roughly 8,600–9,600-pound range, depending on wheelbase, axle ratio, and equipment. Actual payload varied by configuration.

  • Dual rear wheels (DRW) were more common on longer, heavier G30 cargo layouts, though some configurations used single rear wheels depending on the chassis.

  • In the mid‑1990s GM replaced much of the G-series with the Express/Savana naming, but the G-series labels remain in historical documentation and among collectors and repair shops.


In short, that G30 badge signaled a 1-ton capacity within GM's historic van lineup; the definitive confirmation comes from the GVWR label for a given vehicle.


How to verify a G30's weight rating


To determine if a specific Chevy G30 is a true 1-ton configuration, check the official weight rating on the vehicle's documentation and labels.


Before you read the list, consider these steps as the core checks you can perform in person or validate via documents.



  • Inspect the GVWR label on the driver's side door jamb. If the GVWR is around 8,600–9,600 pounds, the vehicle is in the 1-ton class.

  • Look for the exact model designation on the glove box, VIN plate, or build sheet; a "G30" badge or option code often accompanies the 1-ton vans.

  • Note the suspension and wheel setup; DRW configurations and heavy‑duty springs were common on heavier G30 cargo layouts, though some early 1-ton models used single rear wheels depending on configuration.

  • Compare with the VIN and production options; the axle ratio and engine choice can influence payload and GVWR within the same year.


Concluding: The GVWR label is the authoritative source for confirming a G30's classification; the G30 badge indicates 1-ton intent but exact rating depends on configuration.


Modern context: What is the equivalent today?


GM’s modern lineup moved away from the G-series naming to the Chevrolet Express and GMC Savana. The closest contemporary equivalents are the Chevrolet Express 3500 and the GMC Savana 3500, both treated as the 1-ton class in today’s catalog. The 1500 and 2500 variants serve lighter duties and are not direct successors to the G30’s heavy‑duty role.


Before the list: If you’re evaluating a used G30 today, knowing its modern equivalent helps you compare capability and pricing with current models.



  • Chevrolet Express 3500 and GMC Savana 3500 are the direct current 1-ton full-size vans used for cargo, passenger transport, and specialty builds.

  • Modern 3500 vans typically feature updated safety tech, improved efficiency, and chassis improvements while preserving a similar payload range to older G30 models.


Conclusion: For a direct, modern benchmark, look at the Express/Savana 3500 family; the G30 designation belongs to GM’s older labeling system but remains a useful reference for historical capability.


Summary


The Chevy G30 is historically a 1-ton GM van—the label signals one-ton capacity within GM’s older G-series lineup. The authoritative confirmation is the GVWR label, which for typical G30 vans falls in the 8,600–9,600-pound range depending on year and equipment. Today’s GM equivalents are the Chevrolet Express 3500 and GMC Savana 3500, which serve as the current 1-ton full-size van options. When assessing a G30 today, verify the GVWR for an exact classification, and compare with modern Express/Savana 3500 options if you’re evaluating value or capability.
