The 2026 GMC Sierra 3500 HD arrives with only light touch-ups compared to the 2025 model. Updates are limited to fine details such as new exterior color choices and a reduced count of rear-wheel-drive configurations. As a result, the lineup leans even more toward four-wheel-drive models—a pragmatic move that reflects where heavy-duty buyers are steering.

Pricing for the GMC Sierra 3500 HD 2026 starts at $50,195 for the Pro with a short wheelbase and rear-wheel drive. The SLE opens at $54,195, SLT at $68,495, AT4 at $75,395, Denali at $78,695, and Denali Ultimate at $99,795. The most expensive specification is the Denali Ultimate Crew Cab Long Bed DRW 4WD, starting at $103,895.

Those looking to tailor the look of the Sierra 3500 HD have ample choice. Twenty-inch Bright Face wheels with dark-painted pockets are available on SLE and SLT for $1,100, adding a more premium stance. Also on offer are 18-inch polished forged aluminum wheels for Pro, SLE, and SLT at $1,550, while for Denali and Denali Ultimate they come standard—simple upgrades that sharpen curb appeal right from the dealership.
