2024 GMC Sierra 3500 Accessories & Parts

The appeal of heavy-duty pickup trucks lies in their huge towing and hauling power. The GMC Sierra 3500HD delivers the capability you’d expect from this truck segment and teams it with modern tech and superb comfort, especially if the fanciest trim levels are opted for. The Sierra HD comes in a broad array of configurations, giving every truck shopper the model with a set of features they need. If you’re looking for 2024 GMC Sierra 3500 accessories to adapt your rig to your unique preferences, or you need high-quality automotive parts for the repair job or some mods, we’ve got you covered.

What’s New for 2024?

GMC’s HD lineup is due for a mid-cycle refresh this year. First and foremost, it brings turbodiesel-equipped models an increase in engine power and towing capacity. The optional 6.6-liter Duramax V8 now churns out a healthy 470 hp and 975 lb-ft of torque, up 25 horses and 65 lb-ft over the previous model. This resulted in higher maximum towing capability of 36,000 lb. The 6.6-liter gas-burning V8 continues with the same figures, making 401 hp and 464 lb-ft, but this time around, it is bolted to a 10-speed Allison transmission instead of a dated 6-speeder.

This year’s 3500HD received subtle styling tweaks front and rear. The Denali Ultimate model is a new addition to the lineup, and it sits on top of the trim level ladder. As far as the exterior is concerned, exclusive grille and wheel designs separate it from other trims, and on the inside, the Denali Ultimate impresses with fine leather surfaces and a boatload of tech. New electronic trailering assistance systems include a GCW alert feature, adaptive cruise control that functions with the trailer pulled behind, and updated Transparent Trailer View technology.
