I want to put mud flaps on my 13 fx4 extended cab. Want the no drill type and was leaning to the weather tech's. Any body know the part number of the ones I need? I am confused with people mentioning different type that go on fender flares.

I dont know if my truck has flares or not. I didn't add any but the truck has some type of plastic trim around the wheel well but I dont think that is considered a flair.

The truck is bone stock as from the factory.

Thanks.

 

I recommend going to Weathertechs site it is more plug and play you'll see what part number you need then type that into amazon

 

flares and no flares....
stock flares..

weathertech shows 120003 for rear..no listing for fronts if you have the side steps
110003 front

 

steve, my truch is just like the top pic. Guess I do have flairs. That was my main question. Thanks!

 

I just installed the WeatherTech mud flaps in my 13 FX4 with the factory running boards and flairs. I used the Part Number: 110003-120003. The website states if you have the factory boards then you can only use the read guards. But both fit great and look great.

 

^Same part numbers I used on my '13 FX4.
I think the running boards WetherTech is talking about on their web site are the type that are molded right to the fender flare. I don't think it applies to any of the current F150 models. The step bars don't interfere with the front flaps.

 

klondike jim, How good do the flaps funcion? Do they really keep any snow from building up on the running boards? After the first couple snow falls here, I cant believe how much snow and slush was stuck to my boards.

 

They work great. Just made a 700+ mile trip in the snow and the boards were still clear of build up. When I got home I had about 4 inches of buildup on the tailgate but nothing on the running boards. Before I got them installed it was almost to the point I couldn't use the running boards.

 

awesome! im ordering tonight. Thanks
