Find the Right Chevy Silverado 1500 Specs by Configuration
Table of Contents
Which Silverado 1500 are you comparing? Start here
The Silverado 1500 on dealer lots today is really two trucks: the 2019–2026 generation, and the redesigned 2027 model GM says reaches dealerships later this year. Ratings don’t carry from one to the other.
If you’re cross-shopping 2026 and 2027
The 2027 truck changes the engines, trim names and which engine tows most. Start with the model-year section.
If you already own one and need a part
Your cab and bed decide what fits. Jump to the bed section.
If you’re sizing for a trailer or load
Read the towing matrix and payload section, then confirm every number on your own truck’s labels.
If you’re upgrading from an older Silverado
The Duramax diesel’s rating jumped between 2021 and 2022, so an older truck’s figures won’t predict a newer one’s.
ℹ️ Safety Note: Tow ratings and payload depend on your exact build, and exceeding either affects braking and stability, not just performance. The figures here are for comparison. Verify against the trailering label and owner’s manual for your VIN before hitching or loading anything.
📍 Check your own vehicle first: Specifications vary by build date, package and market, and two trucks with the same badge can be built differently. Before you buy anything based on this page, confirm against the Trailering Information Label on the doorframe, the tire and loading placard on the driver-side pillar, and the owner’s manual trailering section. If your truck disagrees with this page, your truck is right.
Where to find your Silverado’s real towing and payload ratings
Every rating on this page is a starting point. Your truck states its own.
The door-jamb labels
GM’s trailering guide puts the maximum trailer rating on the Trailering Information Label on the doorframe. GM’s 2019 guide adds that this label lists GVWR, GCWR, rear axle rating, maximum payload, maximum tongue weight and curb weight. Federal rules place the tire and loading placard on the driver’s side B-pillar.
Where to look:
- Open the driver’s door.
- Find the Trailering Information Label on the doorframe.
- Find the tire and loading placard on the driver-side pillar.
- Compare both against the owner’s manual trailering section.
Owner’s manual and dealer build sheet
The owner’s manual explains what each rating covers. Ask your dealer whether they can pull the build sheet for your VIN, which shows the engine, axle and package your truck has.
Why no chart replaces them
Two Silverados with the same engine can carry different ratings because package, axle and wheels differ. That is why every figure below carries its conditions.
📐 On the Spec Sheet: NHTSA’s Chief Counsel states that a vehicle’s load carrying capacity is its GVWR minus its unloaded weight, and defines vehicle capacity weight as rated cargo plus 150 pounds per designated seating position. Applies to light vehicles under FMVSS 110, including every Silverado 1500 here. Source: NHTSA interpretation on load carrying capacity.
Silverado 1500 model years: what changed and when
2019–2021: launch years and the 4.3L V6
This generation, called the T1XX platform, runs 2019 through 2026. GM’s 2019 trailering guide lists the 4.3L V6, the 2.7L Turbo, and the 5.3L and 6.2L V8s, with 12,200 lbs as the maximum. The Duramax diesel appears in GM’s 2020 chart, topping out at 9,300 lbs.
2022–2026: refresh, TurboMax and diesel changes
The 2022 refresh introduced the ZR2, which uses only the 6.2L V8, and reshuffled which trims offer which engines. GM Authority reads GM’s 2022 chart as rating the Duramax at 13,300 lbs, up from 9,500 in GM’s 2021 chart. For 2023 the diesel rose from 277 hp and 460 lb-ft to 305 hp and 495 lb-ft.
2027: the next-generation truck and its four engines
Trade coverage describes 2027 as a next-generation truck, not an annual update. GM’s September 17, 2026 release lists four engines, all with a 10-speed automatic:
| Engine (2027) | Power | Torque | Replaces |
|---|---|---|---|
| Enhanced TurboMax 2.7L | 350 hp | 455 lb-ft | 2.7L TurboMax |
| Duramax 3.0L diesel | 305 hp | 495 lb-ft | Duramax (updated) |
| L76 5.7L V8 | 402 hp | 428 lb-ft | 5.3L V8 |
| L78 6.6L V8 | 481 hp | 501 lb-ft | 6.2L V8 |
Applies To: 2027 Silverado 1500. Source: GM’s Sept 17, 2026 V8 release.
Which specs carry over
The Duramax’s 305 hp and 495 lb-ft carry over, but its top tow rating doesn’t: 13,300 lbs in 2026, 12,000 lbs in 2027. The 5.3L and 6.2L became the 5.7L and 6.6L.
Silverado 1500 towing capacity by engine, cab and drive
GM publishes a separate tow rating for nearly every engine, cab, bed and drivetrain, and the top number needs specific equipment. Each row shows all three conditions.
2026: engine, cab, bed and drivetrain
GCWR, the most the truck, trailer and everything aboard may weigh together, is 14,000 lbs for the 2.7L and 15,000 lbs for the other engines. Max Trailering raises it to 16,800 lbs (5.3L) or 17,800 lbs (6.2L, Duramax), and 20-inch wheels raise the 6.2L and Duramax to 19,100 lbs.
| Applies To (2026 build) | No package | Max Trailering | Max Trailering + 20-inch |
|---|---|---|---|
| Duramax · Crew Cab Short Bed · 2WD | 9,300 | 12,000 | 13,200 |
| Duramax · Crew Cab Short Bed · 4×4 | 9,000 | 11,800 | 13,000 |
| Duramax · Double Cab Standard Bed · 2WD | 9,300 | 12,100 | 13,300 |
| 6.2L V8 · Crew Cab, short or standard bed · 4×4 | 9,100 | 11,900 | 13,200 |
| 5.3L V8 · Crew Cab Short Bed · 2WD | 9,600 | 11,300 | n/a |
| 5.3L V8 · Double Cab Standard Bed · 2WD | 9,700 | 11,400 | n/a |
| 2.7L Turbo · Regular Cab Long Bed · 2WD | 9,500 | n/a | n/a |
| ZR2 · Crew Cab Short Bed · 4×4 | 8,800 (6.2L) / 8,700 (Duramax) | n/a | n/a |

2019–2025: how ratings moved
| Model year | 2.7L Turbo | 5.3L V8 | 6.2L V8 | Duramax 3.0L |
|---|---|---|---|---|
| 2019 | 7,000 | 11,600 | 12,200 | n/a |

Pounds, Silverado 1500. Source: GM’s Sept 17, 2026 release, which says both vary by configuration, trim and packages.
GM rates each engine’s maximum, not each cab and bed. The sources we checked show no 2027 trailering chart yet.
What each rating requires
🔍 What This Spec Means: Max Trailering is a package, not one part. Cars.com reported that for 2021 it adds a locking rear differential, enhanced cooling, heavy-duty springs, a 3.42 rear axle and a trailer brake controller. The contents are year-specific, so check the order guide for your year.
Why the 13,300-lb Silverado number may not be yours
The wheel condition behind the top ratings
🚫 Fits But Shouldn’t: A 2026 Duramax truck on 18-inch wheels looks the same as one on 20s, but the 13,300 requires 20-inch wheels. GM’s chart shows it: GCWR is 17,800 lbs with Max Trailering alone and 19,100 with the 20-inch wheels, and the same Double Cab 2WD Duramax is listed at 12,100 lbs without them. The condition moved: GM’s 2023 brochure lists 18-inch or 20-inch wheels for the Duramax Double Cab 2WD, while the 2024 and 2026 charts say 20-inch.
If the truck you’re looking at has 18-inch wheels, its rating is the middle column.
Why the 2027 6.6L V8 tows less than the 5.7L
🚫 Fits But Shouldn’t: The 481-hp 6.6L looks like the top engine, but GM rates it at 9,700 lbs against 13,700 lbs for the 402-hp 5.7L. Its 1,510-lb payload is the lowest of the four. The proof is GM’s 2027 powertrain table.
Max Trailering in 2027: one trim, two engines
🚫 Fits But Shouldn’t: An upper-trim 2027 truck with the 5.7L may not be able to carry the 13,700. GM-Trucks’ reading of the order guides says Max Trailering moves to the Silverado trim only, and requires the 5.7L or the Duramax. Dealer material ties 13,700 lbs to that package. Confirm this against GM’s book for your build.
When dealer pages carry the wrong year’s number
A June 2026 dealer page quotes 13,300 lbs for 2027, and an aggregator gives the Duramax 13,300 on 2021 through 2026 models, where GM’s 2021 chart says 9,500.
SAE J2807 is the recommended practice for determining GCWR and trailer weight rating; GM’s documents say whether it applies to a given rating. See SAE J2807.
Silverado 1500 payload by cab, bed and engine
Payload and towing pull against each other: the top tow builds aren’t the top payload builds.
🔍 What This Spec Means: Payload isn’t cargo weight. It is rated capacity, GVWR minus unloaded weight, and it covers passengers, cargo, equipment added afterward, and the trailer’s tongue weight. GM’s guide puts conventional tongue weight at 10% to 15% of loaded trailer weight.
2026 payload by build
| Applies To (2026 build) | Payload (lbs) |
|---|---|
| Crew Cab Short Bed · 2.7L | 2,030 |
| Crew Cab Short Bed · 5.3L + Max Trailering | 2,100 |
| Crew Cab Short Bed · 6.2L + Max Trailering | 2,040 |
| Crew Cab Short Bed · Duramax | 1,950 |
| Regular Cab Long Bed 2WD · 2.7L | 2,260 |
Source: GM-Trucks’ reading of GM’s 2026 order guide, plus dealer material for 2,260. Confirm against the order guide.
2027 payload by engine
GM’s 2027 figures, above, are engine maximums, not Crew Cab Short Bed figures. Don’t subtract 2026 numbers from them.
Why the tow-max truck isn’t the payload-max truck
The 2026 Duramax Crew Cab Short Bed carries 1,950 lbs against 2,030 for the 2.7L. In 2027 the 6.6L carries the least.
⚠️ Watch Out: Sources disagree by 10–20 lbs on the same year: Bomnin lists the 2025 max as 2,260 lbs, Classic Chevrolet as 2,250. The tire and loading placard on your truck is the number that counts.
Silverado 1500 cab and bed sizes by year
Cab and bed choice change the ratings and the accessories that fit, so name yours first.
Which cabs pair with which beds
| Cab | Beds in GM’s 2026 trailering chart |
|---|---|
| Regular Cab | Standard and Long (2WD and 4×4) |
| Double Cab | Standard (2WD and 4×4) |
| Crew Cab | Short and Standard (2WD and 4×4) |
Columns show which combinations GM rates, not which trims offer each. Dealer pages list the same pairings, so a Crew Cab isn’t limited to the short bed, as one dealer guide claims.
Short, standard and long bed dimensions
Dealer pages list the short, standard and long bed floors at 69.92, 79.44 and 98.18 inches, with 62.9, 71.7 and 89.1 cubic feet. Confirm against GM’s specification sheet before publish.
⚠️ Watch Out: One dealer guide lists the standard bed at 78.9 inches and says only two bed lengths exist, yet GM’s chart lists a Regular Cab long bed. Measure your own bed before buying a cover.
Tailgate and cab limits
One dealer page says the 2026 Multi-Flex Tailgate is offered on Regular and Crew Cabs, not Double Cabs. Confirm against GM’s specification sheet.
Silverado 1500 trims and engines by model year
2019–2026 trims and their engines
GM’s 2026 chart lists the 6.2L only in Crew Cab 4×4 columns, matching one dealer’s list of RST Crew Cab 4×4, LT Trail Boss, LTZ 4×4, ZR2 and High Country 4×4. In 2022 the Custom lost the 5.3L, the Custom Trail Boss gained the 6.2L, and the LT gained the Duramax. Trim-by-engine tables for 2019–2021 and 2023–2025:
2027: seven trims, no LT, RST or LTZ
Chevrolet lists seven primary 2027 trims, and the trim called Silverado replaces LT. The order guide has no LT, RST or LTZ. For the 6.6L V8, Silverado shoppers should plan on High Country or ZR2.
Which trims can get Max Trailering
As GM-Trucks reads the 2027 fleet guide, only the Silverado trim offers the NHT Max Trailering Package, and it requires the 5.7L V8 or the Duramax; in 2026 it was available on LT, RST, LTZ and High Country.
Tonneau covers and liners that fit your Silverado bed
Covers and liners are sold by bed length, so your cab-and-bed answer decides what to shop for.
| Bed (GM name) | Floor length (dealer-listed) | What the maker must state |
|---|---|---|
| Short | 69.92 in | Fit for short bed, tailgate type, model years |
| Standard | 79.44 in | Fit for standard bed, tailgate type, model years |
| Long | 98.18 in | Fit for long bed, tailgate type, model years |
✅ Do This: Check the maker’s stated fit for your bed length, tailgate type and model-year range, then measure your inside bed length before ordering.
Which Silverado 1500 configuration fits your use?
If your trailer is heavy
Only certain rows reach 13,000 lbs or more, and each needs Max Trailering. Find the row that matches the truck on the lot, then compare your trailer’s loaded weight and tongue weight to that truck’s label.
✅ Do This: Ask the dealer to read the rated maximum trailer weight, GCWR and hitch class off the label for that VIN.
Comparing brands? See how the F-150, Silverado and Ram compare on towing.
If payload matters more than towing
The highest payloads verified here are 2,260 lbs (2026 Regular Cab Long Bed 2WD, 2.7L) and GM’s 2,340-lb 2027 maximum for the Enhanced TurboMax. On a 2026 Crew Cab Short Bed, the 5.3L with Max Trailering (2,100 lbs) out-carries the 2.7L (2,030) and the Duramax (1,950).
If you’re waiting for the 2027 truck
GM’s release says MSRP comes later, and the sources we checked show no 2027 trailering chart yet. Treat 2027 towing figures as engine maximums until one appears. Cross-shopping the Ford? See F-150 specs by configuration.
Silverado 1500 specs: quick answers
1. How much can a Silverado 1500 tow?
GM’s 2026 chart runs from 8,700 lbs (Duramax ZR2) to 13,300 lbs, which needs a Double Cab 2WD Duramax with Max Trailering and 20-inch wheels. Confirm on your door-jamb label.

6. Can a Silverado 1500 Crew Cab have a standard bed?
Yes. GM’s 2026 trailering chart lists Crew Cab Standard Bed in both 2WD and 4×4, so a Crew Cab isn’t limited to the short bed.
7. Is the 2027 Silverado 1500 a new generation?
It’s described as the next-generation Silverado 1500, not an annual update, with two new V8s and a revised trim lineup.

An Enhanced TurboMax 2.7L, the 3.0L Duramax diesel, and new 5.7L and 6.6L V8s, all paired with a 10-speed automatic.
Before you buy, confirm these on your truck
What to verify before you buy
The rating that counts is on the Trailering Information Label on your truck’s doorframe, so read it before you sign anything. For towing, ask the dealer to read the rated maximum trailer weight, GCWR and hitch class for that VIN, and take payload from the tire and loading placard.
