Key Features

  • Dually set: 110010 front pair plus the wide 120025 dual-rear-wheel rear pair
  • Rear flaps sized for the wider track of a dual-rear-wheel axle
  • Covers the 2007 New Body through 2014 Silverado 3500HD
  • For trucks without fender flares
  • Shares its front pair with the single-rear-wheel 110010-120010 kit
  • No-Drill mounting with QuickTurn stainless fasteners

The WeatherTech 110010-120025 is the dual-rear-wheel version of the GMT900 Silverado mud flap set. It keeps the 110010 front pair and swaps the narrow rear for the wide 120025 dually pair, sized to cover the outer tyre of a dual-rear-wheel axle.

Why a dually needs its own rear flap

The outer tyre on a dually sits several inches further out than on a single-wheel truck, and the fender is shaped to match. A single-wheel rear flap simply does not reach across that tread, leaving the rocker panel and the leading edge of the bed taking the spray. The 120025 is cut for the wider footprint, which is the entire reason this kit exists alongside the 110010-120010.

Fitment

Fits the 2007 New Body through 2014 Chevrolet Silverado 3500HD with dual rear wheels and no fender flares. Only the 3500HD was offered as a dually in this generation, so this set does not apply to a 1500 or a 2500HD.

What the set includes

  • 110010 front MudFlap pair
  • 120025 wide dual-rear-wheel rear MudFlap pair
  • QuickTurn stainless fasteners and clips

FAQ
Will this fit a single-rear-wheel Silverado?

No. The 120025 rear is cut for a dual-rear-wheel axle. A single-wheel truck takes the 110010-120010 set.

Does it fit a 1500 or 2500HD dually?

Chevrolet did not offer either as a dually in this generation, so the question does not arise — this is a 3500HD application.

Is the front flap the same as the single-wheel kit?

Yes. Both kits share the 110010 front; only the rear changes.

Does it require drilling?

No. Both pairs mount to existing factory holes with the supplied QuickTurn fasteners.
