    For those who tow, the ProGrade Trailering System provides intelligent features like the integrated trailer brake controller and the hitch view camera. The in-vehicle trailering app gives you real-time information about your trailer, making towing safer and more manageable. The auxiliary external transmission oil cooler helps maintain optimal performance under demanding conditions.

    The SLT trim delivers comfort with heated and ventilated front seats, a heated steering wheel, and a power-adjustable driver seat with lumbar support. The SLT Preferred Package adds adaptive cruise control, a rear power sliding window, and heated second row outboard seats. Chrome assist steps and 20" polished aluminum wheels from the SLT Premium Package enhance both functionality and appearance.

    The X31 Off-Road and Protection Package equips this Sierra for adventure with all-terrain tires, a spray-on bedliner, and all-weather floor liners. Hill descent control and electronic locking rear differential provide traction when you need it most. The high capacity suspension package supports increased payload and towing demands.
