When ordered for the 2023 GMC Sierra 1500, the 4-inch chromed round assist steps feature is priced at $845. The assist steps are not factory-installed, but are an LPO-level option installed on the truck at the dealership before delivery to the buyer.
The 4-inch chromed assist steps were also unavailable for the 2023 Chevy Silverado 1500 and 2023 Chevy Silverado HD. The feature just returned to availability for the Silverado 1500 and remains unavailable for the Silverado HD.
The 2023 GMC Sierra 1500 saw a price increase in November 2022. It will continue to be produced for another two months, when the 2024 GMC Sierra 1500 will usher in a few minor changes with a start of regular production (SORP) scheduled for July 17th, as previously exclusively reported by GM Authority.
The 2024 model will see the addition of a new safety feature to the truck, in the form of a rear seat belt indicator (RPO code UH5) on all trim levels in the Double Cab and Crew Cab body configurations. The feature notifies the driver which rear passengers have their seat belts fastened via a driver instrument panel graphic.
As a reminder, four different powerplant options are available to motivate the 2023 GMC Sierra 1500. These include the turbocharged 2.7L I4 L3B gasoline engine producing 310 horsepower and 430 pound-feet of torque, the naturally aspirated 5.3L V8 L84 gasoline engine developing 355 horsepower and 383 pound-feet of torque, and the naturally aspirated 6.2L V8 L87 gasoline engine, rated at 420 horsepower and 460 pound-feet of torque.
