Towing capacity is one of the first things Silverado and Sierra buyers check — and one of the most misunderstood specs on the window sticker. The number GM advertises is a maximum under one specific configuration. Your actual towing capacity depends on your engine, cab, bed, drivetrain, axle ratio, wheel package and trailering equipment.
Corrections — this page has been revised against Chevrolet's current trailering figures.
- The 5.3L V8 is rated to 11,300 lbs, not 11,500.
- The 6.2L V8 is rated to 13,200 lbs, not 13,300 — and it is the Duramax diesel, not the 6.2L, that carries the highest figure in the chart.
- The 13,300 lb maximum is a Duramax Double Cab Standard Bed 2WD with the Max Trailering Package and 20-inch wheels — not a 6.2L LTZ/High Country as previously stated.
- The trim table has been removed. Every row of it read "up to 11,500 lbs," which is not how these ratings work — a heavier trim tows less, not the same.
- A weight-distribution hitch is advised for trailers over about 5,000 lbs total weight, not "over 6,000 lbs tongue weight" as previously written. A 6,000 lb tongue weight would imply a trailer far beyond any half-ton's rating.
How GM Calculates Towing Capacity
GM's towing ratings follow the SAE J2807 standard, which defines a standardised test procedure. The rating covers the trailer plus everything in it. It does not account for passengers, fuel or cargo in the truck bed — those come out of your available capacity.
The relationship: Max Towing = GCWR (Gross Combined Weight Rating) − the actual weight of your truck as loaded, including passengers, fuel and bed cargo.
This is why a Silverado with four passengers and a loaded bed tows meaningfully less than the advertised maximum.
2026 Silverado 1500 Towing Capacity by Engine
These are the headline maximums from Chevrolet's current trailering guide. Each one requires a specific configuration — the number is not available on every truck with that engine.
| Engine | Max Conventional Tow | What it takes to get there |
|---|---|---|
| 2.7L TurboMax 4-cyl (310 hp, 430 lb-ft) | 9,500 lbs | Max Trailering Package; highest on Regular Cab long bed |
| 5.3L V8 EcoTec3 (355 hp) | 11,300 lbs | Max Trailering Package; ratings range from about 9,200 lbs depending on configuration |
| 6.2L V8 EcoTec3 (420 hp) | 13,200 lbs | Max Trailering Package |
| 3.0L Duramax Diesel I6 (305 hp, 495 lb-ft) | 13,300 lbs | Double Cab Standard Bed, 2WD, Max Trailering Package, 20-inch wheels |
| ZR2 (off-road configuration) | 8,800 lbs | Suspension and tyre setup reduce the rating substantially |
Two things worth noticing here.
The diesel out-tows the 6.2L, by 100 lbs on the conventional figure, and does it with 495 lb-ft of torque and far better economy under load. If you tow heavy regularly, that is the engine.
The ZR2 is not a towing truck. At 8,800 lbs conventional and around 6,000 lbs gooseneck, the same engine in ZR2 form loses several thousand pounds of capability to its off-road suspension. Buyers cross-shopping a ZR2 against a standard trim for towing should know that before signing.
Gooseneck and Fifth-Wheel — a Surprise
On conventional towing the diesel leads. On gooseneck and fifth-wheel, the current guide tops out at around 10,300 lbs on select 5.3L V8 configurations — so the mid-range V8 carries the highest fifth-wheel figure in the half-ton lineup. If a fifth-wheel is your use case, do not assume the biggest engine is automatically the right answer.

| 2500HD | 6.6L V8 Gas | Up to 17,590 lbs | Up to 18,500 lbs |
| 2500HD | 6.6L Duramax Diesel | Up to 18,500 lbs | Up to 18,500 lbs |
| 3500HD SRW | 6.6L Duramax Diesel | Up to 23,100 lbs | Up to 23,100 lbs |
| 3500HD DRW | 6.6L Duramax Diesel | Up to 23,500 lbs | Up to 36,000 lbs |
GMC Sierra 1500 Towing Capacity
The Sierra 1500 shares its platform, frame, engines and transmissions with the Silverado 1500, and tow ratings are effectively identical when equipped the same way. Denali and AT4X trims use the same engines; AT4X, like the Silverado ZR2, trades towing capability for off-road hardware, so check its specific rating rather than assuming it matches a Denali.
What Actually Affects Your Real-World Towing Capacity
1. Cab, bed and drivetrain
This is the biggest swing. On the 5.3L V8 alone, current ratings run from roughly 9,200 to 11,400 lbs depending on configuration — a spread of more than 2,000 lbs on the same engine. 2WD generally out-tows 4WD because it weighs less, and a Regular Cab out-tows a Crew Cab for the same reason.
2. Max Trailering Package (RPO NHT)
Every headline figure above requires it. NHT adds a higher-capacity rear axle, heavy-duty cooling, upgraded shocks and an integrated trailer brake controller — which you need anyway for heavier trailers. Without it you are leaving 1,000–2,500 lbs on the table.
3. Axle ratio
Check the RPO codes on the glovebox label. A numerically higher ratio generally supports a higher rating on the same truck, at some cost to unloaded fuel economy.
4. Wheel package
Easy to overlook: the 13,300 lb maximum specifically requires 20-inch wheels. Wheel and tyre choice is part of the rating, not a cosmetic decision.
5. Aftermarket modifications
Lift kits, oversized tyres and roof racks add weight and change the geometry. Our estimate is that a 4-inch lift on 35-inch tyres costs 500–1,000 lbs of effective capacity along with fuel economy — and it may put you outside the conditions the rating assumes.
6. Tongue weight
Tongue weight should be 10–15% of total trailer weight. Too little causes sway; too much overloads the rear axle and eats payload. Tongue weight counts against payload, not towing capacity — a distinction that catches people out.
Towing Safety Tips for Silverado & Sierra Owners
- Never exceed GVWR or GCWR — these are hard limits, not targets
- Use Tow/Haul mode on every tow; it changes shift points and engine braking
- Check trailer tyre pressure before every trip — underinflated trailer tyres are a leading cause of blowouts and sway
- Use a weight distribution hitch for trailers over roughly 5,000 lbs total weight, or whenever tongue weight approaches the hitch's rating
- Watch transmission temperature on the driver information centre and keep it in a normal operating range under load
- Change transmission fluid more frequently if you tow regularly
- Allow extra stopping distance — trailer brakes help, but a loaded rig stops far more slowly
How to Find Your Specific Truck's Tow Rating
- Open the driver's door and read the certification label — GVWR and GAWR are printed there
- Check the RPO code sticker in the glovebox — NHT confirms the Max Trailering Package
- Find the original window sticker (Monroney label), which lists the rating for your exact build
- Ask a dealer to look up your VIN if you no longer have the sticker
Do not rely on a chart — including this one — for a purchase or a heavy tow. The numbers above are maximums for particular configurations, and your truck is one specific build.
Frequently Asked Questions
How much can a 2026 Silverado 1500 tow?
Up to 13,300 lbs, but only in one configuration: the 3.0L Duramax diesel in a Double Cab Standard Bed 2WD with the Max Trailering Package and 20-inch wheels. Other engines top out lower — 13,200 lbs for the 6.2L V8, 11,300 lbs for the 5.3L V8 and 9,500 lbs for the 2.7L TurboMax. Every one of those figures requires the Max Trailering Package.
Which Silverado engine tows the most?
The 3.0L Duramax diesel, at 13,300 lbs, narrowly ahead of the 6.2L V8 at 13,200 lbs. The diesel also produces 495 lb-ft of torque and is far more economical under load. For gooseneck or fifth-wheel towing the answer changes: the current guide's highest fifth-wheel figure, around 10,300 lbs, belongs to select 5.3L V8 configurations.
How much can the 5.3L V8 tow?
Up to 11,300 lbs with the Max Trailering Package, but ratings for that engine range from roughly 9,200 lbs upward depending on cab, bed and drivetrain. That is a spread of more than 2,000 lbs on the same engine, which is why the configuration matters more than the badge.
Does the ZR2 tow as much as a regular Silverado?
No, and it is a substantial difference. The ZR2 is rated at about 8,800 lbs conventional and around 6,000 lbs gooseneck, because its off-road suspension and tyres change the geometry the rating depends on. If you are cross-shopping a ZR2 for towing, check its specific figure rather than the lineup maximum. The same caution applies to the GMC Sierra AT4X.
What is the Max Trailering Package and do I need it?
RPO code NHT. It adds a higher-capacity rear axle, heavy-duty cooling, upgraded shocks and an integrated trailer brake controller. Every headline tow figure in Chevrolet's guide assumes it. Without NHT you lose roughly 1,000 to 2,500 lbs of capacity, and you lose the brake controller you would need for a heavier trailer anyway.
Do passengers and cargo reduce my towing capacity?
Yes. Tow ratings are calculated from GCWR minus the truck's weight as it actually sits. Every passenger, every gallon of fuel and everything in the bed comes out of what you can pull. A truck rated at 11,300 lbs empty will not tow 11,300 lbs with four adults and a loaded bed.
Does a Sierra tow the same as a Silverado?
Effectively yes when equipped identically — same platform, frame, engines and transmissions. The exception is the off-road trims: the Sierra AT4X, like the Silverado ZR2, carries a reduced rating compared with a road-biased trim using the same engine.
When do I need a weight distribution hitch?
As a general rule, for trailers over roughly 5,000 lbs total weight, or any time tongue weight approaches the limit of your hitch. A weight distribution hitch transfers load back onto the front axle and steadies the rig. Note that tongue weight counts against payload rather than towing capacity, which is a distinction that trips people up when they are close to a limit.
A Note on Sourcing
The current-model figures on this page — 9,500 lbs for the 2.7L TurboMax, 11,300 lbs for the 5.3L V8, 13,200 lbs for the 6.2L V8, 13,300 lbs for the 3.0L Duramax, the ZR2 ratings and the roughly 10,300 lb fifth-wheel figure — are corroborated across multiple independent sources citing Chevrolet's own trailering guide. We have not opened that guide directly, so these are labelled corroborated rather than verified.
Four figures were corrected in this revision: the 5.3L rating (was 11,500), the 6.2L rating (was 13,300), the configuration credited with the 13,300 lb maximum (was described as a 6.2L LTZ/High Country; it is a Duramax Double Cab Standard Bed 2WD), and the weight distribution hitch threshold (was stated as 6,000 lbs tongue weight).
A trim-by-trim table was also removed rather than corrected. Every row of it gave the same figure, which misrepresents how these ratings work — heavier trims tow less, and the real variation on a single engine exceeds 2,000 lbs.
The earlier-generation tables (2014–2018 and 2007–2013) have not been re-verified in this pass and are carried over from the original article. Treat them as indicative and confirm against your own Monroney label.
The modification impact estimate and the general towing guidance are ours, not manufacturer figures.
Ratings change between model years and configurations. Your window sticker and door-jamb label are authoritative for your truck in a way that no chart can be.
