Dealer Description

Recent Arrival built to conquer. This Dark Sky Metallic 2021 GMC Sierra 1500 AT4 4WD unleashes diesel torque, off-road dominance, and rugged luxury for the driver who charges through mud, mountains, and missions without flinching. Stealth predator stance Dark Sky Metallic cloaks this warrior in shadow, with body-color grille surround, red recovery hooks, and 18-inch machined aluminum wheels that grip terrain like claws. Off-road suspension, hill descent control, and heavy-duty air filter lift it high, ready to devour rocks, ruts, and rivals. Iron throne interior Perforated leather-appointed front buckets with 10-way power adjustments, lumbar support, heated and ventilated fronts, plus heated second-row outboards lock you in for the long haul. Heated steering wheel, dual-zone climate control, and floor-mounted center console deliver command-center control in any storm. Power that pulverizes The 3.0L I6 diesel thunders through 10-speed automatic, auto-locking rear differential, and ProGrade Trailering System with hitch guidance, hitch view, integrated brake controller, and in-vehicle app. Spray-on bed liner with AT4 logo, 120-volt bed outlet, and LED cargo lighting shrug off massive loads like paper. Tech arsenal locked and loaded Premium GMC Infotainment with multi-touch display, SiriusXM 360L, Apple CarPlay, Android Auto, and steering wheel audio controls feed battle intel. HD rear vision camera, deep-tinted glass, Wi-Fi hotspot, and 4G LTE keep you connected while front prem floor liners with removable inserts battle dirt. Fortress-level defenses Electronic stability control, ABS brakes, multiple airbags, and speed-sensing steering hold steady through chaos. Remote start, keyless open, theft deterrent, and engine block heater ensure this beast starts every fight. Rear wheelhouse liners and premium floor protection laugh at abuse. This Sierra AT4 does not whisper through trails. It roars victory, hauls empires, and demands respect from every angle.
