2025 GMC Sierra 2500HD Denali Ultimate

Built to turn heads and equipped to earn its keep, this one-owner lifted 2025 GMC Sierra 2500HD Denali Ultimate Crew Cab 4x4 delivers an incredible combination of custom style, diesel strength and first-class luxury. The Titanium Rush Metallic exterior is set off by gloss-black Ultimate Edition details, while the clean Alpine Umber leather interior gives the cabin a rich, upscale appearance. This Denali has the kind of presence that immediately stands apart from an ordinary heavy-duty truck. The centerpiece of this build is the brand-new, professionally installed 3-inch Rough Country upper-control-arm suspension kit. Brand-new Hostile Titan wheels and massive 37x12.50R20LT Nitto Ridge Grappler all-terrain tires give the truck its wide, aggressive stance and perfect proportions. Power assist steps make getting into this lifted GMC easier, then tuck neatly out of sight when the doors are closed. Animated LED projector headlights, LED fog lights, roof marker lamps and chrome recovery hooks complete the look. Under the hood is the proven 6.6-liter Duramax turbocharged diesel V8 paired with the smooth Allison 10-speed automatic transmission. A two-speed Autotrac transfer case, automatic-locking rear differential, 3.42 axle ratio and digital variable steering assist provide the power and control needed for work, towing and highway travel. StabiliTrak with Trailer Sway Control and Hill Start Assist adds confidence when conditions or loads become more demanding. The Max Trailering Package upgrades this Sierra with the 3500HD frame, heavy-duty leaf springs, a 12-inch rear axle and an enhanced shock package. It also includes gooseneck and fifth-wheel preparation, a factory trailering package, integrated trailer brake controller and GMC’s in-vehicle trailering app. Trailer Side Blind-Zone Alert, a bed-view camera and HD Surround Vision provide valuable visibility when connecting or pulling a trailer. A spray-on bedliner, LED cargo lighting and the versatile GMC MultiPro Tailgate keep the bed ready for tools, equipment or weekend gear. Inside, the Denali Ultimate offers 16-way power front bucket seats, ventilated front seats, heated front and rear outboard seats, driver-seat and mirror memory, wireless charging and a leather-wrapped steering wheel. Technology includes a 13.4-inch color touchscreen with Google built-in compatibility, navigation, Bluetooth, wireless Apple CarPlay and wireless Android Auto. A 12.3-inch digital driver-information display and Bose Premium Series 12-speaker audio system complete the premium cabin. Safety features include Automatic Emergency Braking, Forward Collision Alert, Front Pedestrian Braking, Lane Departure Warning, Rear Cross-Traffic Alert, front and rear parking assistance and the Safety Alert Seat.
