RAM's 2026 Heavy Duty chart does not publish a column labelled curb weight. It publishes GVWR and estimated maximum payload, while RAM's own chart notes define Payload = GVWR – Base Weight. Reversing that stated relationship produces configuration-specific base-weight estimates of 5,970–8,140 lb for the reviewed U.S. RAM 2500 pickup rows. The low endpoint is a 6.4L HEMI Crew Cab with the 6-foot-4-inch box, 4x2 and 9,900-lb GVWR; the high endpoint is a 6.7L high-output Cummins Mega Cab, 4x4 and 10,000- or 11,040-lb GVWR. These are transparent arithmetic results from rounded payload cells, not direct scale weights, VIN certifications or promises about a trim with options. The page keeps the Power Wagon branch, source dashes and gas/diesel configurations separate and does not turn base weight into payload, GVWR, GAWR, GCWR or towing capacity.
Direct answer: the reviewed RAM 2500 base-weight range is 5,970–8,140 lb
For the 2026 U.S. RAM 2500 chart rows reviewed here, calculated base weight spans 5,970–6,995 lb with the 6.4L HEMI V8 and 7,440–8,140 lb with the 6.7L high-output Cummins diesel. The exact result changes with cab, box, drivetrain and the GVWR row used.
The chart calls these inputs estimated and rounds payload to the nearest 10 lb. A subtraction result therefore retains that catalogue precision. It is a comparison baseline, not a claim that an optioned truck will produce the same reading on a scale.
| 2026 RAM 2500 branch | Calculated base-weight span | What sets the endpoints |
|---|---|---|
| 6.4L HEMI V8 | 5,970–6,995 lb | Cab, box, 4x2/4x4, GVWR; includes Power Wagon row |
| 6.7L H.O. Cummins | 7,440–8,140 lb | Cab, box, 4x2/4x4 and GVWR row |
| All reviewed rows | 5,970–8,140 lb | Official chart inputs; arithmetic result, not direct curb-weight cell |
How the RAM chart supports the calculation
RAM's Canadian 2026 chart states the relationship directly: payload equals GVWR minus base weight. Algebraically, base weight equals GVWR minus payload. Each result below subtracts the published maximum-payload cell from the GVWR printed on the same row.
That method does not fill a blank payload cell, average two configurations or move a value across cab columns. A source dash remains unavailable. The U.S. pound chart supplies the transcribed cells; the Canadian chart corroborates the formula and publishes parallel kilogram/pound tables.
| RAM field | Meaning in this guide | Treatment |
|---|---|---|
| GVWR | Maximum rated loaded truck weight for the row | Copied, never treated as curb weight |
| Maximum payload | RAM's estimated payload cell | Copied with 4x2/4x4 order |
| Base weight | GVWR minus maximum payload | Calculated and labelled; rounded-source precision retained |
| Scale weight | Actual truck at a stated condition | Must be measured; never inferred from the chart |
6.4L HEMI rows: 9,900-lb GVWR
At 9,900 lb GVWR, RAM publishes three populated gas pickup columns: Regular Cab long box, Crew Cab 6-foot-4-inch box and Crew Cab long box. Every cell is shown in 4x2/4x4 order.
Subtracting the corresponding maximum-payload values yields the base-weight estimates below. The Mega Cab gas cell is blank in this reviewed row and is not assigned a value.
| Cab and box | 4x2 payload → base | 4x4 payload → base |
|---|---|---|
| Regular Cab, 8-ft box | 3,830 → 6,070 lb | 3,510 → 6,390 lb |
| Crew Cab, 6-ft-4-in box | 3,500 → 6,400 lb | 3,210 → 6,690 lb |
| Crew Cab, 8-ft box | 3,360 → 6,540 lb | 3,020 → 6,880 lb |
| Mega Cab, 6-ft-4-in box | — | — |
6.4L HEMI rows: 10,000-lb GVWR
The 10,000-lb gas row keeps the same three populated cab/box branches but publishes different payload cells. Base-weight results are 6,070–6,890 lb after applying the same subtraction.
A higher GVWR row does not automatically mean a heavier truck. For example, the Regular Cab 4x2 result remains 6,070 lb because RAM raises the published payload by the same 100 lb.
| Cab and box | 4x2 payload → base | 4x4 payload → base |
|---|---|---|
| Regular Cab, 8-ft box | 3,930 → 6,070 lb | 3,630 → 6,370 lb |
| Crew Cab, 6-ft-4-in box | 3,610 → 6,390 lb | 3,320 → 6,680 lb |
| Crew Cab, 8-ft box | 3,470 → 6,530 lb | 3,110 → 6,890 lb |
| Mega Cab, 6-ft-4-in box | — | — |
Power Wagon is a separate gas branch
RAM prints the Power Wagon as a separate 8,565-lb-GVWR row with an unavailable 4x2 cell and a 1,570-lb 4x4 maximum-payload cell. The corresponding calculated base-weight estimate is 6,995 lb.
That row should not be mixed with the 9,900- or 10,000-lb general gas rows. The model identity, 4x4 restriction and different GVWR stay attached to the result.
6.7L Cummins rows: 9,900-lb GVWR
The diesel row adds the Mega Cab and contains several 4x2 dashes. In the chart's 4x2/4x4 convention, Regular Cab and Mega Cab publish only the 4x4 value.
The resulting estimates span 7,440–8,110 lb. Diesel engine identity alone is not enough: cab, box and drivetrain move the baseline by hundreds of pounds.
| Cab and box | 4x2 payload → base | 4x4 payload → base |
|---|---|---|
| Regular Cab, 8-ft box | — | 2,450 → 7,450 lb |
| Crew Cab, 6-ft-4-in box | 2,460 → 7,440 lb | 2,170 → 7,730 lb |
| Crew Cab, 8-ft box | 2,350 → 7,550 lb | 2,010 → 7,890 lb |
| Mega Cab, 6-ft-4-in box | — | 1,790 → 8,110 lb |
6.7L Cummins rows: 10,000-lb GVWR
At 10,000 lb GVWR, calculated diesel base weight spans 7,440–8,140 lb. The Mega Cab 4x4 produces the highest reviewed endpoint because its published maximum payload is 1,860 lb.
Retaining the payload input next to every answer makes the arithmetic auditable and prevents a 10,000-lb GVWR headline from being mistaken for empty weight.
| Cab and box | 4x2 payload → base | 4x4 payload → base |
|---|---|---|
| Regular Cab, 8-ft box | — | 2,550 → 7,450 lb |
| Crew Cab, 6-ft-4-in box | 2,560 → 7,440 lb | 2,260 → 7,740 lb |
| Crew Cab, 8-ft box | 2,460 → 7,540 lb | 2,120 → 7,880 lb |
| Mega Cab, 6-ft-4-in box | — | 1,860 → 8,140 lb |
The 11,040-lb diesel row repeats the same base-weight pattern
RAM's starred 11,040-lb diesel row publishes 3,590, 3,600/3,300, 3,500/3,160 and 2,900 lb across the available cab and drive cells. Subtraction produces 7,450; 7,440/7,740; 7,540/7,880; and 8,140 lb respectively.
The star applies to vehicles with RAM sales codes Z2K, Z7G or Z3Y. The code condition stays with the row; this guide does not translate those codes into a package name that the reviewed chart does not provide.
Why several GVWR rows yield the same base weight
A repeated base-weight result is expected when the same physical branch appears under an alternative GVWR and the published payload changes by the same amount. For example, diesel Crew Cab short-box 4x2 calculates to 7,440 lb at 9,900, 10,000 and 11,040 lb GVWR.
This does not make GVWR interchangeable. The selected certification and loading labels still control the individual truck's rated limit and available payload.
Base weight is not the truck's guaranteed curb weight
Stellantis describes curb weights as estimates that include standard equipment and full fuel, lubricant and coolant. The payload chart separately calls its values estimates and notes that upfit or aftermarket equipment is not included in base weight.
Trim content, factory options, accessories, body additions, tools and other installed equipment can change what a real truck weighs. Use these calculated baselines for configuration comparison, then use a scale for the actual vehicle.
Do not calculate remaining payload from an unverified baseline
Remaining payload belongs to the exact truck and its current load. Start with the tire/loading label, then account for occupants, cargo, accessories, hitch equipment and trailer tongue or pin weight.
Subtracting a generic catalogue base-weight estimate from a family GVWR can conceal option weight. RAM also states that maximum payload and maximum trailer weight are mutually exclusive values, so two separate maxima cannot simply be combined.
GVWR, GAWR and GCWR remain independent limits
GVWR limits the loaded truck, GAWR limits each axle and GCWR limits the loaded combination. Passing one calculation does not prove the others pass. Tire, wheel, hitch and trailer ratings also remain separate.
For a working or towing check, obtain steer-axle, drive-axle and total truck weights, then the combination weight where applicable. Compare each measured value with the exact labels and documentation. @link GVWR, GAWR and GCWR explained | /research/towing/gvwr-gawr-gcwr-explained
The 4x2/4x4 order matters
RAM prints paired values in 4x2/4x4 order. The second number is generally lower payload and therefore a higher calculated base weight, but the order—not that general pattern—controls transcription.
Where the source prints NA before a slash, only the 4x4 value is available. This guide retains each dash rather than assuming a missing 4x2 truck has the same weight.
Cab and box identity must travel with the number
Regular Cab uses the 8-foot box in this chart. Crew Cab has separate 6-foot-4-inch and 8-foot columns, while Mega Cab is shown with the 6-foot-4-inch box. A loose phrase such as crew-cab weight is therefore incomplete.
Record the exact cab and box before selecting a cell. RAMBox, trim and optional equipment are not encoded by these broad columns and still require build evidence and scale verification.
U.S. and Canadian chart precision
The U.S. chart publishes pounds rounded to the nearest 10 lb. The Canadian chart publishes kilograms and pounds and also states that payload and trailer values are estimated and rounded. Small display differences can appear after unit conversion and rounding.
The tables on this page use the U.S. pound cells consistently rather than mixing a converted Canadian cell into one row. Canadian shoppers should verify the exact vehicle labels and market documentation.
How to weigh an actual RAM 2500
Define the condition first: fuel level, occupants, cargo, tools, hitch equipment and trailer connection. Record the scale ticket's date, location and axle splits so another person can reproduce the result.
An empty-truck ticket with full fuel is useful for estimating real payload remaining. A loaded ticket is useful for compliance checks. Neither should be described as factory curb weight unless its condition matches the manufacturer definition.
A reproducible configuration worksheet
Write down model year, pickup identity, engine, cab, box, 4x2 or 4x4, GVWR row and any sales-code condition. Copy the exact payload cell, subtract it from the same-row GVWR and label the result calculated base weight.
Then add the candidate's build sheet, certification label, tire/loading label and scale ticket. A conflict is a reason to stop and resolve identity, not to choose the largest published number.
| Checkpoint | Catalogue record | Vehicle record |
|---|---|---|
| Identity | 2026 RAM 2500 cab/box/engine/drive | VIN and build sheet |
| Rating | Same-row GVWR and payload | Certification and tire/loading labels |
| Baseline | Calculated base-weight estimate | Option and accessory list |
| Actual weight | No catalogue substitute | Axle and total scale weights |
What this guide does not cover
The numeric table is limited to reviewed 2026 RAM 2500 pickup chart rows. It does not publish a complete trim-by-trim order guide, older model-year history, RAM 3500 values, chassis-cab values or a Canadian VIN-specific weight.
It does not establish mechanical condition, reliability, failure rates or legal fitness. No inventory, seller, dealer count, price or offer is asserted; commercial listings remain protected behind their inventory and content gates. @link Browse diesel trucks | /trucks

RAM 2500 curb-weight questions and conclusion
What does a 2026 RAM 2500 weigh? The reviewed chart supports calculated base-weight estimates from 5,970 to 8,140 lb, depending on engine, cab, box, drivetrain and GVWR row. Is that an actual curb weight? No—the result is arithmetic from RAM's rounded estimated payload data.
Which number should be used for a specific truck? Match the exact configuration, read the physical labels and weigh the vehicle in a documented condition. That evidence is more useful than a badge-level average or a single maximum.
Evidence note: manufacturer documents establish the specific facts and applications cited. Buying workflows and cost scenarios are DieselTrucks.ca editorial guidance. These pages do not publish measured failure rates or confirm the condition, recall status or capacity of a particular truck.
