Sterling Metallic 2025 GMC Sierra 1500 AT4X 10-Speed Automatic, 4WD, 3.0L I6
This isn't a truck you drive.
This is a truck you command.
The AT4X is what happens when GMC decides good enough is for everyone else. Built with the 3.0L Duramax diesel, this Sierra delivers the kind of torque that doesn't ask permission it just goes. Whether you're towing, climbing, or pulling into the lot like you own the place this truck backs it up.
Finished in Sterling Metallic, its clean, aggressive, and impossible to ignore. Underneath? Factory-engineered off-road dominance. Lockers. Suspension. Protection. This isn't a lift kit fantasy this is the real thing.
Why this truck separates you from the pack:
Duramax diesel = power + efficiency + respect
AT4X package = off-road authority straight from the factory
4WD system that doesn't flinch when the road disappears
Interior that says luxury while the exterior says don't mess with me
You don't buy this truck because you need it.
You buy it because nothing else feels right after you drive it.

Nice truck
By froggy on Sunday, December 06, 2020
I purchased this truck brand new and at 3900 miles I started to have a misfire. The warranty put a refurbished rebuilt engine in it. I was not aware that the warranty doesn't put new parts in just refurbished rebuilt parts. I traded in and lost my favorite blue truck. Not a fan of the whole process. Love the truck just not how the warranty went. I would not own another brand or model the 2020 is the nicest riding and looking. Just got a bad motor from the manufacture. - 5.0
Great Truck
By Mel on Sunday, April 25, 2021
I love it, I get compliments every where I go, and it apparently worth more than I paid for it brand new, a year and a half later. can't ask for much more than that. - 5.0
Well done GM
By Tony on Thursday, November 26, 2020
This truck has a 10 speed transmission that you can barely feel it shift. Traded in an F150 and test drove a similar equipped Ram. Although the Ram was nice, the styling of the GMC won me over, along with the tailgate! It also pulls my boat way better than the Ford, just smoother all around. The cabin is very quiet and the gas mileage is much better than V8 Ford. The cabin is super quiet and the ride is awesome. Love the adaptive cruise control too. The technology is fine and the screen is plenty big. Remember, you are driving this truck, not going to thr drive in! Most importantly, the controls are simple to use and Bose stereo sounds great! Oh, and I got it cheaper than the similar Ram too!
