Trim Details
4WD Crew Cab Standard Box SLT
The 2018 GMC Sierra 3500HD SLT 4WD Crew Cab Standard Box is a heavy-duty, work-ready truck wrapped in comfort and useful features. The Crew Cab configuration gives plenty of space for passengers up front and in the rear, while the Standard Box bed offers solid cargo utility without making the truck overly long. As an SLT trim, it adds upscale touches beyond the base model: leather-trim seating, dual-zone automatic climate control, heated front buckets, remote start, and power-adjustable pedals. The truck includes four-wheel drive, a heavy-duty suspension with locking rear differential, and a tow-ready setup including an integrated trailer brake controller and auxiliary cooling systems. With its robust frame and towing accessories, it’s built to handle demanding jobs yet still provide a more comfortable ride than basic work trucks.
