This 2024 GMC Sierra HD 20-Inch Wheel Is Currently Unavailable To Order

GM Authority has learned that 20-inch multi-dimensional chrome aluminum wheels (RPO code SKW) are under constraint and currently unavailable to order on the 2024 GMC Sierra HD. This limitation pertains to both the Sierra 2500 HD and Sierra 3500 HD.

It is currently unknown when these 20-inch multi-dimensional wheels will be available to order again on the 2024 GMC Sierra HD.

The 20-inch multi-dimensional chrome aluminum wheels are not factory-installed wheel options but LPO or dealer-installed rollers. When ordered with this wheel choice, the 2024 GMC Sierra HD leaves the GM Flint plant in Michigan on 20-inch transit wheels, with the alignment specs set to match the SKW wheels.

Once the 20-inch multi-dimensional wheels are installed at the dealership, the dealer ships the transit wheels back to the factory. This set of LPO wheels is an extra-charge item normally priced at $3,995. The option is offered on the Denali and Denali Ultimate trim levels only. It is one of the 15 wheel choices available for the 2024 GMC Sierra HD, including seven 20-inch LPO wheel sets.

Notably, the 2024 GMC Sierra HD debuts a mid-cycle refresh, introducing significant changes to its exterior, interior, and powertrain. The pickup’s exterior features a fresh front bumper, fascia, grille designs, and six new paint colors. The cockpit has been fully overhauled, with unique interior treatments for all trim levels and premium design for higher trim levels.

The 2024 GMC Sierra HD offers two different powerplants for motivation. These include the naturally aspirated 6.6L V8 L8T gasoline engine equipped as standard on most trims, developing 401 horsepower and 464 pound-feet of torque, and the optional 6.6L V8 L5P turbodiesel Duramax engine, uprated to 470 horsepower and 975 pound-feet of torque. The range-topping Denali Ultimate trim level gets the turbodiesel engine as standard.

Maximum towing capacity is rated at 21,900 pounds for 2500HD Crew Cab models, 22,500 pounds for 2500HD, and 36,000 pounds for 3500HD. Under the body panels, the GMC Sierra HD is underpinned by a more capable version of the GM T1 platform.
