The 13,300-Pound Tow Rating Is Now A Class-Leading Figure For Diesel Half-Ton Trucks

Back in 2019, MC&T first got official word that General Motors was looking to increase the max towing specs on the Chevrolet Silverado 1500 and GMC Sierra 1500 pickup trucks equipped with the 3.0L LM2 Duramax diesel engine. Because while its smoothness and class-leading fuel economy are impressive, the towing specs fell way short of the competition. So for the 2022 Silverado, Chevrolet announced a big fix to that: a 4,000 pound increase in maximum towing, to 13,300 pounds in 2WD configuration. That’s a 20 percent improvement, and now ahead of the Ram 1500 EcoDiesel, which has a max tow rating of 12,560 pounds.

2022 Chevrolet Silverado 1500 Duramax Engine Upgrades

The biggest upgrades to the 2022 Silverado 1500 equipped with the Duramax straight-six engine were with the chassis, which now allow for the Max Tow Package. The engine is paired exclusively to GM’s 10-speed automatic transmission. Output for the LM2 remains the same for the 2022 model year, at 277 horsepower, and 460 lb-ft of torque. So it’s good to see that the power wasn’t compromised in any way.

Here’s where it gets more interesting. 2022 Silverado 1500 customers will not sacrifice max torque or max towing when it comes between choosing between the LM2 Duramax or the top-shelf 6.2L L87 V8. Both engines feature 460 lb-ft of torque, and both can pull 13,300 pounds in the right configuration. The big decision would be choosing between horsepower (420 in the V8 vs 277 in the diesel), or fuel economy (which is not yet available, but the Duramax is expected to outshine the L87).

Not Available On ZR2

Despite diesel engines having a lot of appeal when it comes to off-roading, the LM2 Duramax diesel engine is not available on the 2022 Chevrolet Silverado ZR2, which will be powered exclusively by the 6.2L L87 V8 engine when the truck launches in Q1 2022. That could perhaps change, but for now, look for the 3.0L Duramax diesel engine to be available on LT, RST, LTZ and High Country trim levels. It’s not available in regular cab configurations, or the entry WT trim level.

Fuel economy for the 2022 Chevrolet Silverado 1500 Duramax is expected to be announced at a later date, and the same goes for the rest of the engine lineup.

Production of the LM2 Duramax is otherwise paused due to supply chain issues stemming from the global microchip shortage, but it’s good to know that Chevrolet plans on keeping the midrange diesel engine around.

Muscle Cars & Trucks was founded by Manoli Katakis - an automotive media veteran that has been covering the latest car news since 2009. His journalism has uncovered dozens of major product changes, updates, plans, and cancellations long before automakers were ready to make things official.

Some highlights over the years of his reporting include the uncovering of the Zora trademark before anybody else reported on the coming of a mid-engine Corvette, as well as the dead-accurate reporting of the coming of the Chevrolet Colorado ZR2, two years before it hit the market, and even before the debut of the concept vehicle. This type of reporting has immediately continued here, with reports of the original seventh-generation Camaro plans being shelved, as well as what's in store for the Chevrolet Silverado.

Some of his work can be found on massive automotive media outlets, such as Motor1. He also has been a guest on the 910AM Radio Station with Detroit News auto critic Henry Payne, as well as the enthusiast-oriented Camaro Show podcast.

Over the years, Manoli has interviewed various automotive industry titans, leaders, and people that make things happen otherwise. These include figureheads such as GM CEO Mary Barra, GM President Mark Reuss, automotive aftermarket icon Ken Lingenfelter, Dodge firebrand Tim Kuniskis, along with various chief engineers of vehicles such as the Ford F-150 & Mustang, Chevrolet Camaro & Corvette, and many more.

At MC&T, Manoli is taking his journalism expertise, deeply planted sources, driving abilities, and automotive industry knowledge to new levels, covering more vehicles and brands than ever before. This is the place where you will continue to read groundbreaking stories about American performance vehicles, pickup trucks, and sport utility vehicles. Here is where you’ll also read insights and quotes from various automotive subject matter experts on the latest relevant products, as well as some of the latest official news from their manufacturers.

Fun facts: he also once beat Corvette Racing driver Tommy Milner in an autocross with a Chevrolet Bolt EV. The biggest vehicle he’s ever driven is a John Deere mining truck. Besides a go-kart, the smallest vehicle he’s driven has been a Hyundai i10. He’s also spent time in the cockpit of various American performance vehicle icons, including the fifth-generation Chevrolet Camaro Z/28, Dodge Challenger Demon, and Ford Mustang GT350R. He has reviewed dozens of trucks, SUVs, and performance vehicles over the years.

One of his favorite new vehicles on the market today happens to be the Chevrolet Colorado ZR2 Bison. He is also a card carrying member of the Sports Car Club of America, and regularly participates in Detroit Region autocross events.

  1. Any idea if this means the Colorado with the same engine will get a towing bump too? Looking for a midsized truck that can tow just a bit more than what the current Colorado is rated for so I have a healthy margin of error.

  2. For those out there that haven’t towed before I’ll say this.
    If your just going to tow a utility trailer every once in a while it’s doesn’t matter which engine you choose. But if your going to tow something that weighs a lot.
    And your going to tow it along ways. the Diesel is the only way to go. the gas mileage will be so much better in the diesel even not towing. And if your going
    to tow out west where the grades are steeper and longer the diesel is the only way to go. The road between Bullhead city, Az and Flagstaff, Az has a 6% grade for 13 miles. The road to Leadville, Co has a 10%

    • With an 8000 lb trailer in tow, I would much rather have the 420 hp of the 6.2 mated with the 10 speed transmission because it’s going to cruise easily up that grade vs the mini duramax which will get there, only much more slowly.
