Semi-Truck Mud Flaps & Mud Guards

Semi truck mud flaps are required on commercial trucks to help deter fly-off debris from hitting other drivers on the road. But they also protect your truck’s wheel wells from harmful road debris. Before you buy a set, choose the right size. Mud flaps should hang 4-6 inches above ground and cover the tire width. You can find standard sizes like: 24x30 - steer axles or single wheel setups, 24x36 or 24x40 for drive axles and trailers, or 24x24 for trailer fenders. Don’t forget to add some semi truck mud flap accessories like anti-sail brackets or mud flap hangers.
