2024 GMC Sierra HD Will Gain Higher Towing Capacity

The forthcoming 2024 GMC Sierra HD is going on sale later in 2023. This heavy-duty truck will gain a couple of improvements. The Sierra HD truck is a towing beast, however, there are more potent vehicles in the segment. It is a nice alternative to Chevrolet Silverado HD. On the other hand, Sierra HD looks more upright, in our opinion.

The interior recently received a major update, and the exterior already looks premium and modern. Still, some upgrades will happen. Even the engine department could gain a power boost. In terms of novelties, GMC will also provide a new trim level, revised front fascia, and much more. The 2024 Sierra HD is almost here, and this is what you need to know about this amazing truck.

Minor Visual Updates

The next 2024 GMC Sierra HD will not receive a redesign. However, some parts of the truck will be upgraded. For a start, the front fascia will host new LED headlights and new LED taillights will dominate the rear section. The manufacturer will also add new turn signals on the back. The grille should suffer a small revision and it could grow in size.

The truck is full of nice chrome accents and it looks very upright. We also expect to see new exterior colors, new optional wheels, and new appearance packages. Reportedly, GMC will introduce new trim level as well. Currently, off-road AT4 and luxury Denali trim levels are the most popular buying options. The lower-grad SLT variant is also quite popular, as it comes with a standard MultiPro tailgate.
