The 2026 GMC Sierra 1500 at a Glance

The 2026 GMC Sierra 1500 combines professional-grade capability with premium craftsmanship, offering four available engines and advanced trailering technologies. Whether you're towing equipment across eastern Oklahoma or commuting between Muskogee and Tulsa, the Sierra is engineered to handle demanding tasks without sacrificing comfort.

Compared to rivals like the Ford F-150, RAM 1500, and Toyota Tundra, the Sierra 1500 distinguishes itself with available Super Cruise® hands-free driving technology, the ProGrade Trailering System, and a more refined approach to truck ownership. Within GMC's truck lineup, it delivers greater capability and space than the Canyon while offering easier day-to-day usability than the heavy-duty Sierra HD.

The lineup includes Pro, SLE, Elevation, SLT, AT4, AT4X, Denali, and Denali Ultimate trims. At Jay Hodge GMC of Muskogee, you can explore the full lineup and compare the features, capabilities, and technology that make each trim unique.
