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.
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.
