GMC Sierra 3500 Models & Options

Given a mid-cycle refresh is on its way, there are no changes in store for the 2023 model year lineup. Five trims allow buyers to pick their desired level of equipment. These include the spartan Pro, the SLE with useful convenience features added, the mid-range SLT that brings upmarket goodies such as a heated steering wheel and heated leather seats, the AT4 with off-road hardware, and the all-out Denali loaded with tech.

Depending on the trim level, the truck is offered with a regular, extended, or crew cab. A notable option is the MultiPro tailgate that can be configured in a variety of ways and serve as a bed extender, a load stopper, a bed step, and more! The heavy-duty Sierra comes offered with robust 6.6-liter V8 engines. The gas-fed version generates 401 horses and 464 pound-feet of twist and is bolted to a 6-speed gearbox. If pulling big trailers regularly is on the docket, the torquey Duramax diesel is a natural choice. This mill churns out 445 hp and a healthy 910 lb-ft, while being paired to a tried-and-tested 10-speed Allison automatic.
