The **2025 GMC Sierra 1500 SLT** steps up to a robust **5.3L V8 engine** paired with a 10-speed automatic transmission-a significant upgrade over the turbo-powered Pro and SLE trims. This trim is specifically built for owners who tow and haul, featuring an available **Max Trailering Package**, automatic locking rear differential, heavier-duty springs, and increased rear axle weight ratings.

The SLT also adds premium touches: 18" machined aluminum wheels with dark grey accents, optional skid plates for protection, and advanced safety tech like Trailer Side Blind Zone Alert. Inside, you'll find upscale materials and the GMC MultiPro Tailgate with optional step lights for convenience.

If towing and hauling are priorities, the SLT delivers the V8 power you need. Contact Markquart Motors at **(715) 833-0444** to learn about current SLT inventory and available trailering packages.
