The official 2026 GM Fleet order guide publishes Chevrolet Silverado 1500 base curb weights from 4,240 to 5,710 lb (1,923 to 2,590 kg) across 53 populated configuration cells. That is a catalogue matrix, not one universal truck weight. Crew, Double or Regular Cab; short, standard or long bed; 2WD or 4WD; L3B, L84, L87 or LZ0 engine; NHT Max Trailering Package; and lifted or ZR2 source columns select the applicable value. Eighteen source positions are blank and remain blank. For an individual truck, its exact build and a scale reading control actual weight.
Direct answer: the reviewed Silverado 1500 cells span 4,240–5,710 lb
The lowest displayed source cell is 4,240 lb (1,923 kg) for the 2WD long-bed Regular Cab with the L84 5.3L V8. The highest is 5,710 lb (2,590 kg) for the short-bed Crew Cab ZR2 with the LZ0 3.0L Duramax. Those are endpoints of the reviewed table, not a valid range for every trim or a substitute for weighing a truck.
The 4,240-lb entry is notably lower than the L3B value in the same column and lower than every other populated cell. This guide preserves GM's displayed value exactly without inventing a correction or package explanation. Confirm the exact build record, labels and scale weight before using it for any calculation.
| Reviewed point | Base curb weight | Exact source boundary |
|---|---|---|
| Lowest displayed cell | 4,240 lb (1,923 kg) | CC10903; Regular Cab long bed; 2WD; L84 |
| Highest displayed cell | 5,710 lb (2,590 kg) | CK10543 ZR2; Crew Cab short bed; 4WD; LZ0 |
| LZ0 diesel cells | 5,030–5,710 lb | Crew or Double Cab; configuration-specific |
| Individual truck | Scale reading | Actual build, fuel, occupants, accessories and cargo |
Match all selectors before choosing a weight
Begin with the 2026 model year, then identify cab, pickup-box length and drive. Next match the engine code and any NHT, lifted or ZR2 source branch. Crew Cab has seven configuration columns, Double Cab has two and Regular Cab has four in the reviewed matrix.
A repeated model code is not always a complete identity. CK10543 appears as ordinary 4WD short-bed Crew Cab, lifted and ZR2 columns. Keep the column label attached to every number instead of treating the shared code as one weight.
| Code or marker | Meaning in this guide | Why it matters |
|---|---|---|
| CC / CK | 2WD / 4WD model-code prefix | Separates drivetrain columns |
| L3B / L84 / L87 / LZ0 | TurboMax / 5.3L V8 / 6.2L V8 / 3.0L Duramax | Selects the powertrain row |
| NHT | Max Trailering Package | Keeps package-specific rows separate |
| Lifted / ZR2 | Distinct source columns | Prevents a base 4WD value from replacing them |
Complete Crew Cab base curb-weight matrix
Each numeric entry below is pounds with kilograms in parentheses. Source blank means the reviewed GM Fleet response displays no base-curb-weight value at that position. It is not zero and is not permission to copy a neighbouring engine or body value.
The U.S. vehicle 23168 and Canadian vehicle 23167 records match across every displayed cell. The seven columns preserve ordinary, lifted and ZR2 branches even when a row contains blanks.
| Engine row | CC10543 2WD short | CK10543 4WD short | CK10543 lifted | CK10543 ZR2 | CC10743 2WD standard | CK10743 4WD standard | CK10743 lifted |
|---|---|---|---|---|---|---|---|
| L3B | 4,700 (2,132) | 4,950 (2,245) | 5,010 (2,273) | Source blank | 4,810 (2,182) | 5,010 (2,273) | 5,070 (2,300) |
| L84 | 4,860 (2,204) | 5,080 (2,304) | 5,130 (2,327) | Source blank | 4,930 (2,236) | 5,130 (2,327) | 5,190 (2,354) |
| L84 + NHT | 4,970 (2,254) | 5,180 (2,350) | Source blank | Source blank | 5,040 (2,286) | 5,240 (2,377) | Source blank |
| L87 | Source blank | 5,180 (2,350) | 5,240 (2,377) | 5,550 (2,517) | Source blank | 5,240 (2,377) | 5,300 (2,404) |
| L87 + NHT | Source blank | 5,220 (2,368) | Source blank | Source blank | Source blank | 5,280 (2,395) | Source blank |
| LZ0 | 5,050 (2,291) | 5,300 (2,404) | 5,390 (2,445) | 5,710 (2,590) | 5,130 (2,327) | 5,350 (2,427) | 5,450 (2,472) |
| LZ0 + NHT | 5,120 (2,322) | 5,330 (2,418) | Source blank | Source blank | 5,190 (2,354) | 5,380 (2,440) | Source blank |
Complete Double Cab matrix
The reviewed Double Cab branch is standard bed, with CC10753 for 2WD and CK10753 for 4WD. L87 has only a 4WD value, and LZ0 remains distinct from the gasoline rows.
NHT differences vary by engine and drive. They should be read from the exact row rather than applied as a universal added-weight formula.
| Engine row | CC10753 2WD standard | CK10753 4WD standard |
|---|---|---|
| L3B | 4,660 (2,114) | 4,940 (2,241) |
| L84 | 4,840 (2,195) | 5,070 (2,300) |
| L84 + NHT | 4,950 (2,245) | 5,130 (2,327) |
| L87 | Source blank | 5,170 (2,345) |
| L87 + NHT | Source blank | 5,210 (2,363) |
| LZ0 | 5,030 (2,282) | 5,280 (2,395) |
| LZ0 + NHT | 5,100 (2,313) | 5,310 (2,409) |
Complete Regular Cab matrix
Regular Cab appears with standard and long beds. The reviewed rows include L3B and L84 only; this matrix does not publish Regular Cab L87 or LZ0 values.
The 4,240-lb long-bed 2WD L84 cell is reproduced as displayed. Its unusual relationship to the 4,510-lb L3B cell in the same column is a reason to verify the specific truck, not a basis for silently changing the source.
| Engine row | CC10703 2WD standard | CK10703 4WD standard | CC10903 2WD long | CK10903 4WD long |
|---|---|---|---|---|
| L3B | 4,410 (2,000) | 4,630 (2,100) | 4,510 (2,046) | 4,750 (2,155) |
| L84 | Source blank | 4,810 (2,182) | 4,240 (1,923) | 4,490 (2,037) |
The 4,240-lb cell is source-bounded, not normalized
GM's reviewed U.S. and Canadian records both display 4,240 lb (1,923 kg) for CC10903 with L84. The cross-market match confirms what the two catalogue responses show, but it does not explain why the value is lower than nearby cells.
No package deletion, typographical correction or engineering rationale is inferred. Anyone using this uncommon branch should verify the build record and weigh the actual truck before calculating payload or trailer margin.
LZ0 diesel cells run from 5,030 to 5,710 lb
The lightest populated LZ0 cell is the 2WD standard-bed Double Cab at 5,030 lb (2,282 kg). The heaviest is the short-bed Crew Cab ZR2 at 5,710 lb (2,590 kg). Ordinary, NHT, lifted and ZR2 branches are not interchangeable.
These values apply only to the reviewed 2026 LZ0 configurations. They do not establish an LM2 weight, another model year, an unseen Canadian VIN or the mass of a truck after accessories and cargo are added.
Lifted and ZR2 columns remain distinct
A lifted CK10543 or CK10743 column is a separate source identity from the ordinary 4WD column. ZR2 is another distinct short-bed Crew Cab column. The differences are not constant across engines.
For example, the LZ0 short-bed Crew Cab values are 5,300 lb for ordinary 4WD, 5,390 lb for lifted and 5,710 lb for ZR2. Those observed cells do not create a formula for any unlisted configuration.
NHT rows must be selected directly
NHT identifies the Max Trailering Package rows in the reviewed matrix. The displayed change from a non-NHT row varies by cab, drive and engine, while lifted and ZR2 NHT positions are blank.
Do not add a fixed package mass to another value. Use the exact NHT row when GM publishes one, preserve blanks, and verify the physical truck's build information.
Source blanks are not zero or universal unavailability
The reviewed payloads contain 18 blank positions among 71 matrix positions. Some appear as null and others as empty visual cells; without an official semantic explanation, both are presented here simply as source blank.
A blank prevents an invented number. It does not prove that every truck with a similar badge is impossible, and it does not authorize borrowing a Sierra 1500, different engine or neighbouring package value.
Base curb weight is not actual scale weight
The order guide labels this field Base Curb weight. It describes a catalogue configuration with nominal equipment, not the measured mass of an individual truck as driven.
Fuel, factory options, dealer accessories, tires, bed equipment, occupants, cargo and hitch hardware can change actual weight. Use a certified scale with the truck in its real operating condition when a loading calculation matters.
Front and rear metadata do not fill missing totals
The official response also exposes front- and rear-weight metadata for model columns. That does not justify summing unrelated rows or manufacturing a total where the Base Curb weight matrix is blank.
Axle-distribution research has its own configuration and equipment boundaries. This guide uses only the explicitly published total cells for the selected engine row.
Payload needs the same truck's evidence
Payload is not a synonym for curb weight. A catalogue subtraction can be useful only when GVWR and curb weight describe the same exact configuration, and even then it does not replace the truck's tire-and-loading label or actual scale weight.
Count occupants, cargo, permanent accessories and carried tongue or pin load. Do not subtract the lightest 4,240-lb catalogue cell from a different truck's highest GVWR to advertise a payload result.
GVWR and axle limits remain separate
GVWR limits the loaded truck, while GAWR limits an individual axle. Tires, wheels and other components add independent constraints. None of those ratings can be inferred from base curb weight alone.
Read the certification and tire-and-loading labels on the completed vehicle. After weighing, compare the actual total and axle weights with each applicable limit.
Curb weight does not establish towing capacity
Trailer rating depends on engine, axle ratio, cab, bed, drivetrain, package and hitch method, with loaded tongue or pin weight returning to the truck. A curb-weight row by itself cannot select that rating.
Use the matching towing evidence, then check GVWR, GAWR, GCWR, tires, hitch and actual loaded weights. The lowest empty catalogue mass is not automatically the best towing configuration.
U.S. and Canadian matrices match cell-for-cell
GM Fleet vehicle 23168 is the reviewed U.S. record and vehicle 23167 is the Canadian record. Retrieved on 13 September 2026, both contain 71 corresponding matrix positions, 53 populated values, 18 blanks and the same 4,240–5,710-lb span.
That agreement is strong catalogue corroboration, not proof of a particular Canadian VIN's equipment or final weight. Confirm market, build and physical labels on the truck being evaluated.
Silverado and Sierra remain separate editorial intents
Chevrolet Silverado 1500 owns this workbook target and canonical URL. The closely related GMC Sierra 1500 has its own established model page and separately researched specification pages.
Shared architecture does not authorize copying an unreviewed sibling value or merging the two pages. This matrix was independently retrieved for the exact Silverado vehicle records.
Source, date and claim limits
Numeric values come from GM Fleet's official 2026 Online Order Guide, independently reviewed in U.S. Silverado 1500 vehicle 23168 and Canadian vehicle 23167 records on 13 September 2026. Chevrolet's current 2026 Silverado page supplies model, cab, trim and engine context rather than replacement curb-weight numbers.
No value is transferred to 2027, an earlier year, Sierra, Silverado HD, chassis cab, modified truck or unreviewed Canadian VIN. This work does not support reliability, failure-rate, inventory, seller, dealer-count, price or offer claims.
Silverado 1500 curb-weight questions and conclusion
What is the 2026 Chevrolet Silverado 1500 curb weight? The reviewed official base cells span 4,240–5,710 lb, but a useful answer requires the exact cab, bed, drive, engine and package branch. Why is the minimum unexpectedly low? The two official market records display the same value, but they do not explain it; verify that configuration rather than inventing a reason.
Is base curb weight the truck's current weight? No. It is catalogue data. Confirm the build, retain every source blank and weigh the operating truck before making payload or towing decisions.
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.
General educational content for Canadian diesel-pickup research. Verify the exact truck, model year, certification labels, owner manual and manufacturer documentation, and obtain qualified mechanical or towing advice where appropriate.
