Several 2024 Chevy Silverado HD trims will no longer offer 12-volt power outlets, GM Authority has learned.
Specifically, the front auxiliary power outlet (RPO code KC5) will be omitted from all trucks of the LT, LTZ, and High Country trim levels. It will still be standard on the Work Truck (WT) and Custom trims of the 2024 Silverado HD. Additionally, the rear auxiliary 12-volt power outlet (RPO code KPA) will also be omitted from all Chevy Silverado HD trims, including WT, Custom, LT, LTZ, and High Country.
By comparison, the 2023 Silverado HD included the front 12-volt outlet (KC5) on all trim levels. The rear 12-volt outlet (KPA) was unavailable on 2023 WT and Custom trims, optional on the LT trim only as part of the Convenience Package (RPO code PCL), and standard on LTZ and High Country.
Despite the removal of 12-volt outlets from multiple trims that previously included them as standard, GM will still build the 2024 Chevy Silverado HD with 400-watt, 120-volt outlets. These household-style outlets will continue to be located in the instrument panel and cargo bed.
These changes follow the removal of the front 12-volt outlets (KD5) from all 2022 Chevy Silverado 1500 trims except the WT, Custom, and Custom Trail Boss. 120-volt outlets in the instrument panel (KI4) and bed (KC9) were added as standard on all trim levels except WT, in which both are optional.
As such, it would appear that GM is moving toward offering 120-volt outlets on both the Silverado 1500 and Silverado HD as it removes 12-volt outlets from most trims of the full-size trucks.
As a reminder, the 2024 Chevy Silverado HD brings about the truck’s mid-cycle refresh. Among its updates and new features are a revised front fascia with new headlights to deliver a bolder and more modern appearance. Even bigger news for the 2024 model year is the introduction of a completely overhauled cockpit for LT, LTZ, and High Country trims, headlined by a new 12.3-inch digital gauge cluster and a new center stack with a 13.4-inch center display. Unlike the refreshed Silverado 1500, the HD retains the column-mounted shifter.
Additionally, a new GCW Alert gives drivers the ability to monitor Gross Combination Weight while trailering. Meanwhile, the 2024 Silverado HD is making the switch to the newer and more powerful GM Global B electronic architecture that delivers improved infotainment, communications, and electronics processing power.
The 2024 Silverado HD is available with a choice of two engines. The first is the naturally-aspirated 6.6L V8 L8T gasoline engine rated at 401 horsepower and 464 pound-feet of torque. The second is the 6.6L V8 L5P turbodiesel Duramax engine that is now rated at 470 horsepower and 975 pound-feet of torque, a significant boost compared to ratings of 445 horsepower and 910 pound-feet of torque prior to the 2024-model-year refresh. All 2024 Silverado HD trucks feature the Allison-branded 10-speed automatic transmission as standard on both gasoline and diesel models.
Under the skin, the 2024 Chevy Silverado HD rides on a more-capable variant of the GM T1 platform.
GM will open the order banks for the refreshed 2024 Silverado HD on January 19th, with the exception of the upcoming 2024 Chevy Silverado HD ZR2 trim. The Silverado HD ZR2 off-road-oriented variant with increased ground clearance, improved traction, plus front and rear locking differentials, will become available to order later in 2023. Previously, GM Authority exclusively reported that the start of regular production (SORP) for the 2024 Chevy Silverado HD is scheduled for February 2023.
