Pro: Built for the Everyday Professional
The Pro trim serves as the strong foundation of the 2026 Sierra 1500 lineup. Powered by GMC’s robust TurboMax™ 2.7L I-4 engine delivering 310 horsepower and 430 lbs.-ft. of torque, this model pairs impressive strength with practical versatility.

Inside, a driver-centric cabin and durable materials ensure both comfort and utility. The Pro trim is ideal for Westbrook-area drivers who need reliability and toughness wrapped in GMC’s unmistakable style.
SLE: Capability Meets Comfort
Moving up to the SLE trim introduces a refined balance of performance and technology. The cabin is enhanced with a 13.4-inch infotainment display and a 12.3-inch Driver Information Center, both seamlessly integrated into the modern dash. Heated front seats and a heated steering wheel add comfort when Maine winters roll in.
Under the hood, the available 3.0L Duramax® Turbo-Diesel engine offers impressive torque and towing power, while premium materials throughout the cabin create a truck that’s as at home on city streets as it is on rural roads.
Elevation: Confident and Contemporary
The Elevation trim brings a bolder aesthetic to the Sierra 1500 lineup with a monochromatic exterior, black-mesh grille, and 20-inch gloss-black painted aluminum wheels. It’s a head-turner designed for those who appreciate a sleek, modern edge.
Inside, available leather-appointed front seating and dual-zone automatic climate control make every drive comfortable, while the available power sunroof adds an open-air touch of luxury. Elevation captures the essence of GMC design — bold, confident, and effortlessly capable.
SLT: Refined Power and Premium Detail
The SLT trim brings a heightened sense of sophistication with its 5.3L V8 engine, chrome accents, and 10-way power-adjustable front seats with lumbar support. The interior introduces refined finishes and available ProGrade Trailering System for seamless towing.
For drivers in Westbrook who demand both functionality and elevated comfort, the SLT is the perfect midpoint between practicality and prestige — a truck that transitions effortlessly from work to weekend.
AT4: Off-Road Readiness with Style
The AT4 trim embraces adventure with authentic off-road engineering. It features a factory-installed 2-inch lift, off-road-tuned suspension, and underbody skid plates designed to conquer rugged terrain. The Hill Descent Control and four-wheel-drive system enhance stability and confidence on every trail.
Inside, the Jet Black interior with Kalahari accents and perforated leather seating surfaces blend luxury with utility. The AT4 is built for drivers who expect their truck to perform as boldly as it looks — from the mountains to the Maine backroads.
AT4X: The Ultimate Off-Road Performer
At the frontier of capability sits the AT4X, the Sierra 1500’s most advanced off-road trim. Building on the AT4’s rugged foundation, the AT4X adds Multimatic DSSV™ dampers, front and rear e-lockers, and off-road-optimized suspension for exceptional articulation and control.
Its distinctive design features A-pillar rock protectors, red recovery hooks, and exclusive AT4X badging. Inside, full-grain leather seating, a 15-inch Head-Up Display, and available massaging front seats redefine off-road luxury. This trim is purpose-built for those who crave adventure without compromising refinement — proof that GMC’s engineering excellence knows no limits.
Denali: The Standard of Luxury
Few names carry the prestige of Denali, and in the 2026 Sierra 1500, it represents a flawless marriage of craftsmanship and innovation. Signature chrome detailing, real open-pore wood trim, and Forge perforated leather seating elevate the cabin experience.
The Denali also features available Super Cruise™ hands-free driving technology on compatible roads, providing a glimpse into the future of luxury driving. With commanding presence and intuitive comfort, the Denali continues to set the benchmark for upscale trucks.
Denali Ultimate: The Pinnacle of Professional Grade
