The SLT steps up with a robust 5.3L V8 engine paired with a 10-speed automatic transmission, setting it apart from lower trims. This trim is built for serious trailering and hauling, with an available Max Trailering Package, automatic locking rear differential, heavier-duty springs, and increased rear axle weight ratings. Premium 18" 6-spoke machined aluminum wheels with Dark Grey Metallic accents enhance the look. Optional skid plates and black recovery hooks add rugged capability. Inside, you get upscale touches and advanced safety tech including Trailer Side Blind Zone Alert. The SLT is ideal for buyers who tow or haul regularly.
