The 2021 Chevy Silverado HD is no longer available with the optional Convenience Package II upgrade, GM Authority has learned, due to a supplier constraint. It’s currently unclear whether or not the package will become available to order again for the remainder of 2021 model-year Silverado HD production.
The optional Convenience Package II upgrade was previously offered on 2021 Chevy Silverado 2500HD LT and 3500HD LT trim levels, including all available configurations. The Convenience Package II upgrade is tagged with RPO code PCM, and includes the following content (relevant RPO code listed in parentheses):
- 120-volt power outlet (KI4)
- 120-volt bed-mounted power outlet (KC9)
- Chevrolet Infotainment System with 8-inch diagonal color touch-screen (IOS)
- USB ports, SiriusXM with 360L (MCR)
- HD radio (U2L)
- HD Rear Vision Camera (UVB)
- Hitch Guidance with Hitch View (PZ8)
- Advanced Trailering System (U1D)
Additionally, Crew Cab and Double Cab models included a rear sliding power window (A48) and Universal Home Remote (UG1).
As GM Authority covered previously, the 2021 Chevy Silverado HD is no longer available with the Advanced Trailering Package, either.
The latest 2021 Chevy Silverado HD is the second model year of the fourth-generation vehicle, which debuted for the 2020 model year. The Silverado HD is offered with two engine options, with the naturally aspirated 6.6L V8 L8T gas engine making 401 horsepower and 464 pound-feet of torque, and the 6.6L V8 L5P turbodiesel Duramax making 445 horsepower and 910 pound-feet of torque. The 6.6L V8 gas engine connects to a six-speed automatic transmission, whereas the 6.6L V8 diesel engine connects to a 10-speed automatic transmission.
