The 2025 Sierra 1500 SLT is the first trim to unlock a 5.3L V8 engine paired with a 10-speed automatic transmission-a major step up in power and towing capability. It's engineered for owners who haul and tow regularly, with available Max Trailering Package, automatic locking rear differential, heavier-duty springs, and increased rear axle ratings. The SLT rides on 18-inch machined aluminum wheels and features available skid plates and enhanced safety tech like Trailer Side Blind Zone Alert. Inside, upscale touches and the GMC MultiPro Tailgate (available with Step Lights) add refinement and utility. If towing and hauling are priorities, the SLT delivers the muscle you need.
