Key Features

  • Front and rear set: 110011 front pair plus the wide 120025 dually rear pair
  • Covers the 2007 New Body through 2014 GMC Sierra 3500HD dually
  • For trucks without add-on fender flares or lip molding

  • No-Drill mounting with QuickTurn stainless fasteners

The WeatherTech 110011-120025 is the GMT900-generation GMC Sierra dually set, covering the 2007 New Body through 2014.

An older kit than its catalogue text suggests

This part is sometimes listed as a 2014-and-newer fitment. It is the opposite: it belongs to the previous GMT900 truck and ends in 2014 rather than beginning there. If you have a 2015 or later Sierra HD, this is not your kit — and if you have a 2007, check whether it is the New Body or the carry-over Classic, because only the New Body is covered.

Fitment

Fits the 2007 New Body through 2014 GMC Sierra 3500HD with dual rear wheels, without add-on fender flares or lip moulding.

What the set includes

  • 110011 front MudFlap pair
  • 120025 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
Is this a 2014-and-newer kit?

No. It runs from the 2007 New Body to 2014. Listings suggesting otherwise are repeating a bad supplier string.

Will it fit a single-rear-wheel Sierra?

No. Those take the 110011-120011 kit.

Does it fit a 2500HD dually?

GMC did not offer a dually 2500HD in this generation, so the question does not arise.
