Lifted AT4 HD Build from Orr GMC Longview
The 2026 GMC Sierra 2500HD AT4 already delivers one of the best factory combinations of luxury and off-road capability in the heavy-duty truck market.
Built by Orr GMC in Longview, Texas, this AT4HD takes things further with a clean suspension and wheel setup centered around a set of 8-lug 22×10″ JTX DRIVE DX-1 wheels wrapped in 37-inch Toyo tires.
The truck sits on a 5-inch Zone Offroad lift kit, giving it the additional height needed to properly support the larger wheel and tire package while still keeping the truck balanced and highly usable.
Finished in a light metallic gray with contrasting black trim and red recovery hooks, the gloss black DX-1 setup ties the entire build together cleanly.

Why This Setup Works
The AT4 platform already has strong factory proportions, so the goal with this build was to enhance the truck without overcomplicating it.
The 5-inch lift gives the truck additional height while maintaining a clean overall profile, and the 37-inch Toyo tire setup adds the right amount of sidewall and off-road character.
The DX-1 wheel design works especially well on the GMC platform because of its clean spoke layout and modern styling, pairing naturally with the truck’s factory body lines and trim.
Combined with the gloss black finish, the setup gives the truck a more aggressive look while still keeping the premium feel expected from an AT4HD build.
Why DRIVE
The JTX DRIVE Series was built specifically for modern truck and SUV platforms that demand both strength and refined styling.
Using advanced flow formed / rotary forged barrel construction, DRIVE wheels reduce rotational weight while increasing barrel strength compared to traditional cast wheels.
The result is a wheel that delivers premium styling and performance characteristics while remaining purpose-built for heavy-duty truck applications.
This AT4HD is a perfect example of that balance.
Final Take
Clean.
Refined.
Capable.
Orr GMC put together an extremely well-balanced AT4HD build, and the DX-1 setup fits the platform perfectly.
