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
DZ17939 uses a black plastic design with an 18 × 11-inch listed size. Verify the exact vehicle application.
DZ1800 has a 16 × 12-inch aluminum rectangular outline without the radius notch of the 1808 series.
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.
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.
