Blend-material 18x24 mud flaps in a shallow style, built at 1/4 in. thick for work truck and fleet use. The 18 in. by 24 in. face hangs behind the wheel to hold back stones, slush and spray, and the 1/4 in. section gives it more body than the thin .150 in. flaps in the same size. Nominal size: 18 in. wide x 24 in. high Material thickness: 1/4 in. Blend material, listed as a shallow style Heavier section than the .150 in. flap offered in the same 18x24 size Confirm hanger width and bolt spacing before ordering Sizes are given width by height, so measure across the top edge of the flap coming off rather than the visible drop. Check that the hanger bar width and bolt hole spacing suit an 18 in. flap, and allow for the extra weight of a 1/4 in. section on the hanger. Order enough units for a matched set across the axle.
