Dealer notes
This pre-owned 2021 GMC Sierra 1500 SLT Crew Cab with short bed and four-wheel drive is available now at Napleton Buick GMC in Crystal Lake, with 64,400 miles on the clock. Finished in Satin Steel Metallic — a warm medium-gray metallic — with Jet Black perforated leather-appointed front outboard seating, it arrives with three factory packages that together make it one of the more purpose-built SLT configurations you'll find: the X31 Off-Road Package, the Snow Plow Prep Package, and the Preferred Equipment Group 4SA trailering suite.

The X31 Off-Road Package and Snow Plow Prep Package are what separate this truck from a standard SLT build. X31 brings off-road suspension, a two-speed electronic AutoTrac transfer case, skid plates, hill descent control, a heavy-duty air filter, and dual exhaust with premium tips.
The Snow Plow Prep Package adds a 220-amp alternator and its own skid plate reinforcement — the electrical capacity to run plow lighting without taxing the charging system. Underfoot, 18-inch six-spoke machined aluminum wheels wear 265/65R18 all-terrain blackwall tires, with a full-size 265/70R17 all-season spare on board.
The Preferred Equipment Group 4SA loads the comfort and capability side: heated front seats, remote vehicle starter, keyless open and start, deep-tinted glass, rear wheelhouse liners, LED cargo area lighting, a front license plate kit, and front frame-mounted recovery hooks. For towing, the package includes the ProGrade Trailering System , an integrated trailer brake controller, an auxiliary external transmission oil cooler, and an auto-locking rear differential.
Connectivity comes from the Premium GMC Infotainment System with an 8-inch color touchscreen, Apple CarPlay, Android Auto, smart device mirroring, rear dual USB charging ports, a 120-volt instrument panel outlet, and 4G LTE Wi-Fi hotspot capability.
Napleton Buick GMC sits on Northwest Highway (US-14) in Crystal Lake, close to the Metra UP-NW line and convenient for drivers coming from Barrington, Fox River Grove, and Carpentersville. We've been a family-owned group for more than 80 years, and there's no pressure in the process — just straightforward answers.
If this truck fits the work you have in mind, we're ready when you are.
