The WeatherTech 110036-120076 is the K2XX-generation GMC Sierra dually set, 2015 through 2019, for trucks without factory fender lip or add-on flares.

Where this generation ends

The heavy-duty Sierra ran on the K2XX body from 2015 to 2019 before the current truck arrived for 2020. This kit stops there. Catalogue text describing it as fitting anything from 2015 onward is repeating an open-ended supplier string rather than an application table.

Fitment

Fits 2015-2019 GMC Sierra 3500HD with dual rear wheels, without factory fender lip or add-on fender flares. Single-rear-wheel trucks of these years take the 120036 rear instead.

What the set includes

  • 110036 front MudFlap pair
  • 120076 wide dual-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 fit a 2020 Sierra 3500HD?

No. The 2020 truck is the current generation and takes the 110120-120122 set.

Will it fit a single-rear-wheel Sierra?

No. Those take the 110036-120036 kit.

Is the Chevrolet Silverado version the same part?

No. The Silverado uses the 110035 front; they are separately tooled.
