Key Features

  • Single-rear-wheel applications

The WeatherTech 110120-120120 fits the current GMC Sierra heavy duty, 2020 onward, on single-rear-wheel trucks.

Denali is a trim, not a fitment

WeatherTech sells one product for the Sierra and the Sierra Denali — the Denali badge changes the interior and the grille, not the wheel arch. What does change the part is the rear axle: count the rear wheels, and if there are four, you need the 120122 rear instead.

Fitment

Fits 2020-2026 GMC Sierra 2500HD and 3500HD, including Denali trim, with single rear wheels.

What the set includes

  • 110120 front MudFlap pair
  • 120120 single-rear-wheel rear MudFlap pair
  • QuickTurn fasteners and clips

Each flap is laser-measured to the vehicle's own body contour and mounts to existing factory holes with WeatherTech's QuickTurn stainless fasteners — no drilling into painted metal, no trimming, no wheel removal.

FAQ
Does it cover the Sierra Denali?

Yes. Denali is a trim level and uses the same flaps.

Will it fit a dually?

No. A dual-rear-wheel 3500HD takes the 110120-120122 set.

Can I use the Chevrolet Silverado kit instead?

No. WeatherTech tools the Sierra and Silverado separately and they are not interchangeable.
