ProGrade Trailering System: Technology for Towing Smarter

Even though you’ve got all the raw power of the 2026 GMC Sierra 1500, sometimes it’s not easy to know how to fully unleash that potential, or you might feel a little nervous about hooking up a big trailer for the first time. GMC thought about that, which is why they packed the Sierra 1500 with a “brain” to help you tow smarter. The ProGrade Trailering System takes the guesswork out of every haul. Instead of stressing over trailer lights, tire pressure, or pre-trip checks, you get tools that guide you step by step. It allows you to:

• Set up five custom trailer profiles so your truck “remembers” each trailer, including type and hitch.
• Monitor trailer tire pressure in real time.
• Run an automatic light check to make sure everything’s working before you drive off.
• Receive maintenance reminders to stay on top of both truck and trailer.
• Follow pre-departure checklists to make sure nothing is missed.
