The 2023 GMC Sierra HD introduces a handful of changes and updates, dropping in as the final model year before the arrival of the fully refreshed 2024 GMC Sierra HD. Now, GM Authority has learned that production of 2023 GMC Sierra HD Regular Cab and Double Cab body styles is under constraint.
According to sources familiar with the matter, GM will only build units of the 2023 GMC Sierra HD in the Crew Cab body style, starting with production in late October. The constraint for 2023 GMC Sierra HD Regular Cab and Double Cab models is not related to a supplier issue or shortage, but rather is a corporate decision. The constraint will likely change over time.
The official online configurator for the 2023 GMC Sierra HD went online at GM’s website several months ago. As of this writing, Regular Cab and Double Cab body styles are still listed among the configurator options.
Per previous GM Authority coverage, pricing for the 2023 GMC Sierra HD has increased compared to equivalent 2022 model-year vehicles, with the MSRP rising by $1,000 across the board, including both Sierra 2500HD and Sierra 3500HD models. As such, the least-expensive 2023 GMC Sierra HD model in the lineup, specifically, the Sierra Pro with the Regular Cab / Long Bed body configuration, rear-wheel drive, and 6.6L V8 L8T gasoline engine, is now priced at $44,770, including destination freight charge (DFC). However, with this new constraint in place, the least-expensive model available to order is the 2023 GMC Sierra 2500HD Pro in the Crew Cab / Standard Bed configuration with rear-wheel drive and the 6.6L V8 L8T gasoline engine, which starts at $49,170, including DFC.
In addition to offering the 6.6L V8 L8T gasoline engine, the 2023 GMC Sierra HD can also be had with the 6.6L V8 L5P turbodiesel Duramax engine. Production got underway at the GM Flint plant in Michigan on July 18th.
