New GMC Sierra Trucks near Lubbock, TX

A Half-Ton That Earns Its Keep on Panhandle Roads

Stock trailers, caliche roads, feed runs, and a hundred highway miles before lunch. The GMC Sierra near Lubbock, TX, is built for exactly that kind of week, with four engines, eight trims, and a tailgate that does six different jobs before you ever load the bed. 

• Four engines run from a torque-heavy turbo four-cylinder to a 6.2L V8 and a Duramax turbo-diesel.
• Max available diesel towing reaches 13,300 pounds, and payload climbs as high as 2,230 pounds.
• The chart below lays out features on all eight trims, from Pro to Denali Ultimate.

At Greg Lair GMC, we have been selling trucks to Panhandle families and businesses for more than 30 years, and we carry one of the largest GMC selections in Texas. Every truck that leaves our lot also carries our free Lifetime Powertrain Warranty, which few dealers can say.

Four Engines, No Wrong Answer

The standard TurboMax engine surprises people. It makes 310 horsepower and best-in-class standard torque of 430 lb-ft, pairs with an 8-speed automatic, and returns an EPA-estimated 18 mpg city and 21 mpg highway. It tows up to 9,400 pounds and carries a 5-year, 100,000-mile powertrain limited warranty. For a truck that lives mostly on pavement with an occasional trailer behind it, that covers the job.

Heavier work brings the bigger options into play. The 5.3L V8 is standard on the SLT and Denali; the 6.2L V8 is available on AT4 and AT4X and standard on Denali Ultimate; and all three V8S use a 10-speed automatic. Then there is the Duramax 3.0L Turbo-Diesel, standard on both AT4 models and available almost everywhere else. That diesel is what gets a GMC Sierra to its 13,300-pound max tow rating, set up as a Double Cab 2WD with standard bed, the Max Trailering Package, and 20-inch wheels.

The Bed and Tailgate Do Half the Work

The six-function MultiPro tailgate is the feature owners use every day. It works as a standard tailgate, an inner gate for oversized loads, a bed step, a load stop, and a fold-out work surface, all without tools. Pair it with the available CarbonPro composite bed, which resists dents, scratches, and rust while offering best-in-class short bed cargo volume, and you have a bed built for hard use.

Payload depends on how the truck is built. Regular Cab models handle up to 2,230 pounds, Double Cab standard bed up to 2,040 pounds, Crew Cab short bed up to 2,020 pounds, and Crew Cab standard bed up to 1,950 pounds. The available ProGrade Trailering System gathers hitch guidance, trailer diagnostics, and up to 14 camera views in one place, which makes backing a gooseneck into a tight pen far less of a two-person job.

A Cab Worth Spending the Day In

Crew Cab models offer best-in-class standard front head and legroom, and rear passengers get 43.40 inches of legroom compared to 35.24 inches in the Double Cab. That gap decides it for most families. Heated front seats and a heated steering wheel are available at the SLE level, and leather appointments carry through Elevation, SLT, and Denali trims.

A 13.4-inch touchscreen with Google built in and a 12.3-inch Driver Information Center combine for over 40 inches of driver-focused digital display, the most in the class. GMC Pro Safety is standard, with forward collision alert, automatic emergency braking with pedestrian detection, and lane keep assist. Super Cruise hands-free driving is available on the Denali, and standard on Denali Ultimate, and anyone who has fought I-27 in a headwind knows why that matters.

Reading about a truck and sitting in one are two different things. Seat height, ride quality on a washboard road, and bed height when you are loading it all answer themselves in ten minutes behind the wheel, which is why we keep several trims on the ground.

GMC Sierra Trim Levels for Drivers near Lubbock, TX

Trim shopping is where most truck buyers stall out, so here is the full ladder side by side. Standard equipment carries over as you climb, meaning each trim keeps what the one below it offers and adds to it.

Standard and available equipment varies by cab style, bed length, and drivetrain, so treat the chart as a starting point and let us confirm the details for a specific truck.
