Dee Zee mud flaps and splashguards help shield the truck body and surrounding traffic from road spray and debris. This selection includes a black plastic guard and three Brite-Tread aluminum options with different dimensions, finishes and notches. Compare the shape and installation method before choosing a pair.

Plastic, rectangular aluminum and radius-notch designs

Contoured plastic

DZ17939 uses a black plastic design with an 18 × 11-inch listed size. Verify the exact vehicle application.

Straight Brite-Tread

DZ1800 has a 16 × 12-inch aluminum rectangular outline without the radius notch of the 1808 series.

Radius-notch Brite-Tread

DZ1808 and DZ1808TB are 19 × 11-inch aluminum guards; the finish differs between silver and textured black.

Dee Zee mud flap sizes and mounting styles

All four models are sold as pairs. Each product uses a different combination of size, construction and outline, and their suitability depends on the specific mounting area.

MPN Overall size Material and finish Outline Fit check
DZ17939 18 × 11 in Black plastic Contoured rectangle Check specified F-250 application; catalog shorthand is ambiguous
DZ1800 16 × 12 in Aluminum; coated finish Straight rectangular outline Universal-style; measure wheel opening and clearance
DZ1808 19 × 11 in Silver aluminum Radius notch at top Multi-fit; verify wheel-opening shape
DZ1808TB 19 × 11 in Textured black-coated aluminum Radius notch at top Multi-fit; verify wheel-opening shape

Installation and clearance checks

Measure the exposed tire width, wheel-well mounting space and clearance at full suspension movement. Follow the product-specific installation instructions; these four catalog listings indicate drilling is required. Confirm the mounting substrate and fastener placement before making holes.

A listed dimension is not guaranteed vehicle fitment

Dee Zee's 19-inch radius-notch splashguards may require different mounting locations from a straight 16-inch rectangle. Check tire clearance and body-panel geometry, especially on vehicles with factory fender flares or running boards.

No model here is documented as including logos, insert panels or anti-sail stiffeners. Check the individual listing for package contents and mounting hardware.
