2026 GMC Sierra 1500 · The X31 Off-Road Package
Which 2026 GMC Sierra 1500 trims have the X31 Off-Road Package?
Four of the eight trims confirmed. The X31 Off-Road Package is optional on the Pro, SLE, Elevation and SLT. Our data doesn't verify it on the AT4, Denali, AT4X and Denali Ultimate. We don't have every option price, so we can't say which Sierra with it costs least.
Our Sierra data has eight 2026 Sierra 1500 on the Crew Cab short bed, their modeled engines, drive systems and core towing and off-road . It doesn't have other cabs and beds, HD or EV trucks, paint, dealer or every equipment package yet, so something missing from this page may still be offered.
