The **Sierra 1500 SLT** steps up to a robust 5.3L V8 engine paired with a 10-speed automatic transmission-a major upgrade that unlocks serious towing and hauling capability.

It includes an available Max Trailering Package, automatic locking rear differential, heavier-duty springs, and increased rear axle weight ratings designed for serious work. The SLT rides on 18" 6-spoke machined aluminum wheels and offers available skid plates for durability. Inside, you get upscale touches and advanced options like the GMC MultiPro Tailgate with available Step Lights and enhanced safety tech including Trailer Side Blind Zone Alert.

If towing and hauling are priorities, the SLT delivers the power and features you need. Call Markquart Motors at (715) 833-0444 to learn more about SLT specifications and availability.
