Mud Flap Weights

Prevent mud flaps from flaring, slapping, or twisting at highway speeds with heavy-duty mud flap weights and stabilizers from American Radiator. These essential components add downward tension to your flaps, maintaining a smooth profile and minimizing vibration-induced wear—even under high airflow, wind, or debris loads.

Our mud flap weights are made from corrosion-resistant materials like cast zinc, powder-coated steel, or reinforced polymer. Designed to pair with standard and oversized mud flaps, they distribute weight evenly along the lower edge to reduce flap flutter and keep them positioned for maximum spray control. Compatible with major trucks like Freightliner, Kenworth, Peterbilt, Volvo, and International, they enhance effectiveness without interfering with ground clearance or trailer clearance constraints.

Using the proper weight helps your mud flaps resist aerodynamic uplift, improving their performance in wet, windy, or highway conditions. American Radiator stocks a full range of weights and stabilizing accessories, including mounting brackets, safety chains, and counterweight assemblies. With expert support and fast shipping, selecting the right mud flap weights is simple and reliable.

Trust American Radiator for mud flap weights that deliver controlled stability, extended flap life, and cleaner operations mile after mile—making your fleet safer and cleaner in every condition.
