Before ordering, it is best to read these pages to determine the right length of mud flap for your truck.

How To Determine Your Length of Mudflap

Step 1: Measure from point 1 down to where you want the bottom of your mudflap to be. Once you have determined the Length (or the closest length to it), you can order below, by first selecting your Style, then by clicking the “To Order” button, there you will be able to choose Mudflap Length.

Tips To Consider Before You Decide On Length

  1. Your truck will be lower when loaded than when empty.
  2. If fitting for towing purposes, it is preferable to attach the trailer first to take your measurements, and then take the same measurements with your trailer disconnected.
  3. You should not have the mudflaps closer to the ground than 6 inches when the truck is unloaded as natural obstructions such as a parking lot bumper stop is normally 6 inches high off the ground. If you should back into such an obstacle and pinch the mudflap between the obstacle and the tire, possible damage to the truck and or mudflap may occur.
  4. Although we are happy to provide CUSTOM LENGTH mudflaps to your specifications and have great success in filling specific needs, any customer requested custom alterations or owner specifications will negate our usual return policy.
  5. Make sure to read “How to Determine Length of Mudflap” (above) and “Lifted Truck Bracket Installation” pages (below).
Customer requested specifications will not affect our standard guarantee against factory defects. Lifted Truck Bracket Installation Instructions - Front Bracket Installation - Rear Bracket Installation

Patented Drill-less Installation

  • Don’t add more holes to your truck – avoid additional rust spots.
  • NO guess work – Our Mudflaps are designed to be centered behind the tires.
  • Other mud flaps take more time and precision to install correctly and often require the removal of your tires to fit a drill into position.

Most Protection for your Truck

  • We offer FULL-size Mud Flaps for optimum protection of your vehicle and what you tow.
  • The others sell narrow, short splash guards, which do not provide the protection your truck deserves.

Perfect Fit Everytime

  • Only DuraFlap offers computerized cutting and custom sizes to provide the perfect fit every time.
  • Have a Modified Truck?  We are the only mud flap company that can custom fit a drill-less mud flap to your truck.

Best Materials

  • The DuraFlap Guarantee
  • 3/8″ thick Polyethylene/Rubber blend material – will not crack, peel, tear or fade.
  • Rain Grooves direct the rain, mud, and snow down to the road – Flat surfaces allow these to work their way around the mud flap to hit the truck
  • Anti Sail design – Reinforced edges keep the mud flap from flying up behind the vehicle as it moves down the road

Motor Home Fender Wells – some feedback from purchase made in August with motorhome that has tires that are out past the edge of unit, the stock flares do not do adequate job of keeping mud , stones, debris from getting all over the back sides of the unit. Installing your Duraflaps has made a huge difference on the ability to keep it clean and looking good.

Installation was relatively pain free only had to remove outside dual to gain easy access for drill and driver.

One incision to make bending around factory flare and good to go photos attached to add to your album, will recommend to others for sure installed on 2017 Concord 300DS by Coachman
