2023 Chevy Silverado Unavailable To Order With Duramax Diesel And NHT Trailering Package Together12
The 2023 Chevy Silverado 1500 stands as the fifth model year of the fourth-generation Bow Tie brand’s venerable light-duty pickup truck. Now, GM Authority has learned that the 2023 Silverado 1500 is currently unavailable to be ordered with a combination of the Duramax diesel engine and the trailering package.
GM Authority sources tell us that prospective buyers can no longer order the Max Trailering Package (RPO code NHT) in conjunction with the 3.0L I6 LZ0 turbodiesel Duramax engine on a 2023 Silverado 1500. As of the time of this writing, it’s unclear as to why the trailering package cannot be ordered with the diesel, or how longer this constraint will be in effect.
It’s worth noting that customers can still option the Max Trailering Package with either one of the 5.3L V8 L84 and 6.2L V8 L87 gasoline engines.
Normally, the Max Trailering Package is available as an option on LT, RST, LTZ and High Country trim levels, and includes a suite of features intended to increase pulling capabilities (relevant RPO code in parenthesis):
- 9.76-inch rear axle
- Enhanced cooling radiator
- Revised shock tuning for increased control
- Heavier duty rear springs
- Increased RGAWR
- 220-amp alternator (RPO code KW5)
- Trailer brake controller (LT and RST) (RPO code JL1)
It’s worth noting that the highest tow ratings for the Silverado 1500 can be reached with both the Duramax diesel engine and the 6.2L L87, when combined with the NTH trailering package. The truck’s max tow rating is set at 13,300 pounds.
As a reminder, the 2023 Chevy Silverado is offered with four different engine options. These powerplant choices include the turbocharged 2.7L I4 L3B gasoline engine, rated at 310 horsepower and 430 pound-feet of torque, the atmospheric 5.3L V8 L84 gasoline engine, rated at 355 horsepower and 383 pound-feet of torque, the atmospheric 6.2L V8 L87 gasoline engine, rated at 420 horsepower and 460 pound-feet of torque, and the 3.0L I6 LZ0 turbodiesel Duramax, rated at 305 horsepower and 495 pound-feet of torque.
In regard to transmission options, the L3B is matched to the GM eight-speed automatic, while the L84, the L87 and the LZ0 are offered with the GM 10-speed automatic.
Under the skin, the Silverado rides on the GM T1 platform, which it shares with its corporate platform-mate, the 2023 GMC Sierra 1500. Production takes place at the GM Fort Wayne plant in Indiana, the GM Silao plant in Mexico, and the GM Oshawa plant in Canada.

GM: “We think diesels are not what our buyers are looking for when towing heavy weight trailers laden down with extra weight. …”
What about 3.73 gears,the most important part of the NHT option!
That’s the only thing that makes sense – a supply issue with 3.73’s, which are 100% unique to LZ0 with NHT. I would speculate that for every 3.73 gear set they probably use at least 100 3.23’s.
Here is the problem with the standard 3.23 final drive. Its lacking decent payload, and is why so many want the max tow. I tow 7000lbs and have a 960lb tongue weight. Most folks are over 10% GVW of the trailer for tongue weight.
Thanks GM. Sold the sizzle and hosed us on providing the steak. When will you figure out that you will lose customers each time you pull this stunt.
It’s because of the trailer breaking doesn’t work with the 3.0 and gets disabled when driving. They can’t figure out a fix and people are getting killed as a result.
This is literally the truck I ordered. Need the max tow and the diesel. Ordered this in august. Does this mean my truck won’t be built if it’s already been ordered?
Well that’s a deal breaker altogether.
Could be lz0 specific parts for the enhanced cooling.
You could try a Sierra. I ordered at the dealer my LZ0 SLT Crew standard box with max tow in Nov. 2022. Dealer called two weeks ago and GM scheduled it for production at the end of March. GM’s fleet order guide does not currently list this constraint on the Sierra’s. Only the Silverado’s are affected to my knowledge
The problem with your Sierra SLT Crew with standard bed is the same with any GMC, you get the max tow and you DO NOT get the two speed transfer case. A truck without a low range is not a truck at all. Do you hear me GM!
