Unlike the lower versions, the SLT comes with the 5. 3-liter V8 engine as standard. Together with the sleek ten-speed automatic transmission, this translates into sleeker, tougher performance. The SLT only supports the Crew Cab frame style, so there’s more cab area. It’s in the SLE but adds 18-inch alloys, LED fog lights, power-folding side mirrors, interior and exterior mirrors with automatic dimming, rear window defroster, perimeter lighting, rain-sensing wipers, leather-upholstered exterior front seats, a front passenger seat with ten-way force adjustment, and a reminiscence formula for driver’s seat positions and mirrors.
