GaeaAuto's Black Straight Mudflap Hanger Bracket is a heavy-duty, spring-loaded steel mounting set with 1-1/8" bolt spacing designed to hold 30" mudflaps and 24"x3" DOT-C2 aluminum reflectors on semi trucks.

Built for long-haul durability, this mudflap hanger bracket set combines a corrosion-resistant black finish, spring loading for flex, and pre-measured bolt spacing so you can replace or upgrade your mudflap hardware quickly. The package includes a matching left and right steel hanger, nuts and bolts for the mounting studs, mounting hardware for mudflaps, and a pair of adhesive aluminum reflective strips with DOT-C2 conspicuity tape for improved night visibility.

How does the 1-1/8" bolt spacing simplify installation?

The fixed 1-1/8" (1.125") center-to-center bolt spacing fits common semi truck mounting studs, letting you swap out worn hangers without modifying your frame. Because the kit includes nuts, bolts and mudflap fasteners, most installs are bolt-on and require no cutting or drilling.

What materials and construction ensure long-term performance?

Each hanger is stamped from heavy-duty steel and finished with a black corrosion-resistant coating to withstand road salts, moisture and repeated flex. The spring-loaded design adds controlled give when the flap contacts obstacles, reducing stress on the mount and mudflap.
