For the Ford F-350 Super Duty with dual rear wheels AND OE fender flares
Completes the four-way flare-by-axle matrix for this platform

Single-rear-wheel flared trucks use 110066-120066
No-Drill mounting with QuickTurn stainless fasteners

The WeatherTech 110066-120074 is the flared dually corner of the current Super Duty range — the flare-contoured 110066 front paired with the wide 120074 dual-rear-wheel rear.

Completing the matrix

Four combinations cover this platform, and this is the one for a dually that came with factory flares. Its three siblings are the plain-arch dually (110065-120074), the flared single-wheel (110066-120066) and the plain-arch single-wheel (110065-120065). The rear tells you the axle; the front tells you the fenders.

Fitment

Fits 2017-2020 Ford F-350 Super Duty with dual rear wheels and OE fender flares. If your truck is a 2021 or 2022 dually with flares, contact us before ordering — published fitment data for those years is inconsistent and we would rather check than guess.

What the set includes

110066 front MudFlap pair, contoured for OE flares
120074 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 single-rear-wheel truck?

No. That truck takes the narrower 120066 rear.

What if my dually has no flares?

Then the 110065 front is correct, sold as the 110065-120074 kit.

Why is the year range shorter than the other kits?

Published application data for this specific flared-dually combination is thinner than for its siblings, so we list only the years we can stand behind.
