How to Make a Full Width Mud Flap


A full width mud flap is a large, single mud flap that extends across the entire rear of a truck. Unlike regular mud flaps, full width flaps protect the entire body of the vehicle, as well as anything being towed, from mud and debris. They are usually upwards of $200 to $300 to purchase, so it may be a better idea to make one yourself. The parts needed may take a little diligence to find, but the money saved will make the effort well worth it.

Things You'll Need

  • Strip of conveyor belt rubber (at least the length of your vehicle's width)
  • Metal bracket (total length of the rubber, 2 inches in width)
  • Rubber cutting shears
  • Electric drill
  • Bolts (1-inch length, 1/4-inch width) with nuts
  • Tape measure
  • Hitch mount
  • Wrench set
  • Measure the width of the vehicle's rear bumper and cut the belt's length accordingly.

  • Measure the distance from the bottom of the rear bumper to the ground and neatly cut the the belt's width roughly 6 inches shorter.

  • Align the bracket with the top of the flap and overlap about an inch of space. Drill 1/4-inch holes approximately 8 inches apart across the entire flap on the overlapped area. Fasten the rubber to the bracket using the bolts. Use a wrench to tighten the nuts as much as possible.

  • Attach the bracket to the hitch mount. Fasten the mount so that the bracket sits above it, parallel with the bottom of the bumper.

Tips & Warnings

  • You may wish to cut the rubber in the middle to allow the tow hitch to have room in between. Depending on the type of vehicle and hitch, this may or may not inhibit your ability to tow.
