2025 GMC Sierra 2500HD AT4X

CERTIFIED DIESEL POWER WITH A PREMIUM EDGE The 2025 GMC Sierra 2500 AT4X in Volcanic Red Tintcoat brings a heavier, bolder kind of presence to the road, the kind of truck that looks ready before the day even begins.

With power fold and extend trailer mirrors with auto-dimming, a GMC MultiPro tailgate, and a spray-on bedliner, this certified Sierra feels built for drivers who want serious capability wrapped in something that still feels sharp, modern, and unmistakably commanding.

Under the hood, the Duramax 6.6L Turbo-Diesel and Allison 10-speed automatic transmission deliver the kind of deep, effortless strength that makes towing, hauling, and rough-weather driving feel calmer and more controlled.

Backed by a rear electronic locking differential, 2-speed Autotrac transfer case, trailering package, trailer brake controller, and vehicle trailering app, this is the kind of heavy-duty truck that feels fully prepared for long weekends, hard jobs, and roads that do not stay easy for long.

Inside, the cabin balances hard-use strength with real comfort.

The Obsidian Rush interior, dual-zone automatic climate control, 16-way power front bucket seats with storage package, driver seat and mirror memory, heated front and rear outboard seats, ventilated front seats, and 60/40 rear folding bench seat give this Sierra a richer, more settled feel from the first mile to the last.

It feels like the kind of truck you can work out of all day and still enjoy climbing back into after dark.

Technology keeps that confidence high with the Premium GMC infotainment system, 13.4-inch touchscreen with Google built-in compatibility, wireless Apple CarPlay and Android Auto, HD Surround Vision, front and rear park assist, trailer side blind zone alert, forward collision alert, automatic emergency braking, front pedestrian braking, and lane departure warning.

Add the gooseneck / 5th wheel package, high idle switch, upfitter switch kit, and snow plow prep / camper package, and this Sierra feels built for drivers who expect their truck to think ahead as hard as it works.

From Blissfield, Pontiac, and Quincy along I-96, US-127, and M-34 through Hillsdale County, Livingston County, and Kalamazoo County, to Bowling Green, Napoleon, and Whitehouse across I-75, US-20, and OH-25 in Fulton County, Paulding County, and Ottawa County, this certified Sierra 2500 AT4X brings diesel authority and heavy-duty confidence to the roads that shape real work.

And through Albion, Fremont, and Leo-Cedarville by way of I-69, US-30, and IN-101 across Steube
