Recycled Rubber Mud Flaps

These truck or trailer mud flaps are 1/4" thick and constructed of 100% recycled rubber. They are flexible and forgiving so - unlike polymer (hard plastic) flaps - they won't break if they hit something on the road. The durable rubber can also withstand subfreezing temperatures, so these flaps won't get brittle when the rain turns to snow and ice.

Easy Installation

If you already have mounting brackets in place on your truck or trailer, installation is as simple as lining up the pre-drilled holes on these flaps with your mounting plate. If the holes don't quite line up, you can easily drill new ones.

Well made, thick reinforced rubber.


The mud flaps look real durable. However they don’t come with bolts or anything to mount. Wish it did.

I do have an alternate set of mud flaps that do come with installation hardware. They are part # A37DC

-- Etrailer Expert Jenny N - 12/02/2021


Didn't fit properly. etrailer wouldn't do ANYTHING about it.

This item does not fit single rear wheels with add-on fender flares, which you told a representative you have.
-- Etrailer Expert Sierra K - 09/08/2021

2018 Ram 2500

These are made of thick rubber. We are using them on a trailer. I am happy with this purchase.


These are very nice thick mud flaps I do like them I sort of customize them

2011 Chevrolet Silverado

well these are the real thing not flimsy at all. cant say as for druabilty because i just put them on my 2011 silverado i live in upstate N.Y where the winters are cold and snowy so far seem rugged.


These mud flaps worked great on my boat trailer. I had to cut them down to fit, but I get asked about them by other boat owners regularly.


Exactly what I ordered. Fast shipping also. Will do business with them again in the future.


Great heavy duty mudflaps.


The Mud Flaps were just as described, excellent quality!


Great mudflap for single tire trailers and pickups


Everything arrived on time and was perfect thank you


Perfect size for my truck bed wheel well. Idea thickness to last and withstand bending when driving.

2017 Forest River Rockwood Mini Lite Travel Trailer

I purchased mud flaps for my travel trailer from etrailer. They arrived on the promised date, they were heavy duty and well built, as described on their web site, and they were easy to install. Very satisfied.


Exactly what I was looking for, priced right, received right away, would recommend and use again


Quality product. Great service as always. Thick and heavy duty, they should last forever. These look great on my truck and protect my 5th wheel from all rocks.


I was a little skeptical ordering these, because I thought they would be thin or cheaply made. Boy was I wrong! These are great and very durable. I highly recommend ordering. I will order from you guys again.


Great quality product. Shipping was fast and the people at etrailer are awesome. Great company to do business with.


Customer service is great! The shipment arrived on time. Product material is sturdy and a good value for the price. Will definitely buy from Etrailer again.


The entire experience from shopping to checking out felt seamless. Received product which was as advertised. I'm pleased and plan to shop again!


Delivered quickly and worked well. Made in the USA.


I have not installed them yet. Looks like they are made of a good material. They should work just fine.


thanks , they will look great on my 1932 ford flatbed pickup truck . they are exactly what i wanted , Everette.


good product shipped fast

2019 Ford F-150

It’s what I was expecting it will fit perfectly to my truck and the quality of the material!

  • 2022 Toyota 4Runner Mud Flap Fitment with Limited Model
    The Truck Mud Flaps # 337B1218LSP will fit your 2022 Toyota 4Runner but they are a universal fit so you'll have to essentially modify them to make them fit. All of the mud flaps we have listed have this universal fitment which is why you're having trouble finding custom fit options - because there aren't any. I have attached some review videos for you to get a good idea how these work.

  • Are the Buyers Products Universal Fit Mud Flaps Easy To Cut To Size
    I have a solution for you, and while you could potentially cut down the Buyers Products # 337B1218LSP, they're fairly thick an durable and cutting may be a challenge without the right tools. If you do need to trim them I would recommend using a tin snips. Instead of going that route, I recommend that you have a look at the Buyers Products # 337B1412LSP which are 14" wide and only 12" tall, as opposed to the # 337B1218LSP which are 12" wide and 18" tall. These are the same mud flaps in...

  • Mud Flap Recommendation to Fit Rear of Fifth Wheel Trailer without Trailer Hitch
    The Rock Tamers Heavy-Duty, Adjustable Mud Flap System for 2" Hitches - Matte Black # ERT00108 are designed to be mounted to the hitch receiver, but you could directly mount the flaps if desired to the bumper or frame. Another option so you don't purchase unneeded hardware is the Buyers Products Mud Flaps - Black Rubber - 12" Wide x 18" Tall x 1/4" Thick # 337B1218LSP which can be mounted to your bumper, wheel well or frame if desired.

  • Recommended Mud Flaps For A 2022 Wolf Pup Limited 16BHS Travel Trailer
    I may have a solution for you, however we do not currently carry mud flaps that are designed to specifically fit towed trailers like your 2022 Wolf Pup Limited 16BHS. We carry the Buyers Products Mud Flaps - Black Rubber - 12" Wide x 18" Tall x 1/4" Thick # 337B1218LSP which can be mounted to your bumper, wheel well or frame if desired.

  • Do Buyer's Products Mud Flaps Include Hardware
    The Buyer's Products mud flaps, part # 337B1218LSP, do not include mounting hardware so you need to source it locally. I recommend stainless steel machine screws and nuts but anything that's coated and can handle the elements will work. Another similar sized option is the Rockstar Splash guards, part # AC84FR. The hardware is included with these.

  • How do Mud Flaps Install on my 2019 Ram 3500?
    The Buyers Products Mud Flaps part # 337B1218LSP do not have a specific installation process as this is something that is more of a universal fit. On your 2019 Ram 3500 you would trim the flap to fit the contour of your fender well and attach it to the steel that runs around the inner edge of the fender using fasteners of your choice (self tapping screws or machine bolts and nuts). For a custom fit application I recommend using the WeatherTech Mud Flaps part # WT110108-120108 this is...

  • Custom Fit Mud Flaps for a 2019 GMC Sierra 2500
    I do have an option for you but the Buyers Products Mud Flaps part # 337B1218LSP are more or less for commercial use like what you would see on a semi. I am not sure there would be a good way to mount these on your 2019 GMC Sierra 2500. Instead, I recommend you take a look at the WeatherTech Mud Flaps part # WT120036 for the rear or part # WT110036 for the front. These are no-drill options that are super easy to install and you don't need to make any mounting bracket for them. I have...
