These 1/2" super heavy-duty rubber semi-truck mud flaps are built to withstand the toughest road and weather conditions. Measuring 24" x 30", each flap is molded from thick, reinforced rubber that resists tearing, cracking, and curling under heavy use. The front side is designed with chevron-patterned corners to enhance splash control and keep road spray down, while the back side features an innovative spiked surface that helps shed mud, snow, and debris to maintain performance and appearance over time. A tire-cord reinforced header adds exceptional strength at the mounting point, preventing sagging or pull-through even under constant vibration and extreme temperatures. With their rugged construction and long service life, these mud flaps provide reliable protection for trucks, trailers, and surrounding vehicles, keeping debris contained and roadways safer. Sold as a pair, they combine function, durability, and resistance to harsh environments for professional-grade performance.
