On the questionnaire it asks about whether my truck has flares or not. What are flares??

When we ask about flares we are talking about the extra flare package or wheel well molding that is often added around the wheel wells of the truck. These are either plastic or fiberglass. On several truck models, these flares make it necessary for us to redesign the drill-less truck mud flaps to work with different factory holes.

Here are sample photos of trucks with flares and without flares:

Drill-less…really? How do you do that?

Where possible we pre drill the mudflap to match factory holes already in your fender well lip. However, with the new styles, there are trucks with very little fender well lip and some with no holes in the fender well lip.

Our design team has designed some great brackets to use in these circumstances. To get install directions complete the form on our "Ask the Experts" page. Fill in your truck details and we will send you the install directions for your truck, and a couple of photos of your model with our mudflaps on it. Under the comments section, you can let us know if you are interested in any of our custom weight designs or designs not shown, and we will try to find images of that weight installed.

Do I need the standard length or the extra long?

We design our drill-less mudflaps to hang approximately 9-10" off the ground. Our extra long are designed to hang our maximum length of 7" off the ground. These are the lengths measured on the trucks we get into our shop for the design and fit up. Your truck could sit differently depending on wheel and tire sizes, suspension model and year. Each mudflap description includes how far below the fenderwell the mudflap will hang. So measure your truck and verify that the length listed will work. We are measuring from just below the lowest part of your fenderwell behind the tire. The extra long mudflaps are designed to give maximum protection to a trailer or boat being pulled. When you hook your tow vehicle to your truck it may squat a little, but you should not have to worry about backing into curbs or parking lot blocks when you are towing, so a little closer to the ground should be okay.


Will your drill-less work with aftermarket fender flares?

We also need to know about aftermarket flares. These may cover the factory holes we use, and may require you to drill thru the flare to use the factory hole underneath. If you have aftermarket flares, visit our Ask the Experts page to complete our questionnaire and we will send you the install directions with some photos of installs. Review our install directions for your truck application, and determine if you can reach all the necessary parts on the fenderwell. Many of the aftermarket flares use the same holes that we do for installation, and it is just a matter of removing the bolts they used, and using our slightly longer bolts or screws.

The other possible problem with aftermarket flares is if they have a curved edge where the fenderwell lip is usually flat. This curvature may keep your mudflap from sitting flat.

One last thing to check for is how much wider the flare lip is then the factory flare. If the inside edge is wider than the factory flares, some of our hardware may not be designed to reach around the edge. You may end up having to drill holes after all. Sometimes, it is just a better bet to order our standard installation mudflaps to be certain they will work with those non-factory flares. While we are able to make exchanges on our stock mudflaps, the customer is required to pay the shipping, and that can get costly.

I have oversized tires; can I get mudflaps that will not rub?

With the extra large tires being sold today there is a problem of the tires rubbing on the mudflap that hangs straight down inside the fender well. This is especially true for the front mudflaps when turning the wheel.

We cannot say if you will have a rub issue just based on your tire size. Other factors that affect the rubbing are lifts and truck stance. We always suggest that you place a piece of cardboard inside your wheel well where the mudflap will be hanging down, and turn your front wheels to verify that they will not rub. Our mudflaps are 3/8" thick, so use thicker cardboard to be safe.

If there is a rub issue we recommend our lifted truck brackets...

We design our drill-less mud flaps to be centered on stock tires. If you place a ruler across the tread, centered on the tire, this will show you the coverage you will get from our 12" wide mud flaps. When we design the 14" wide mud flap, we add 1" to the inside and 1" to the outside to keep the mud flap centered on the tire. If your tires stick out 1" or less beyond the fender well, half way up on the wheel well, our 14" wide mud flap should cover out that far. If you have aftermarket, offset wheels you will want to phone and discuss the possibility of us customizing the mud flaps to give you more coverage, and keep your mud flaps centered to your tires. We call this an offset.

If the tires stick out extremely far this may require you to purchase our standard installation mud flaps so you have the ability to position them exactly where you need them.

It does mean drilling holes in your fender well, but if your tires stick out that far, you have probably already been drilling holes elsewhere

These are typical coverage for our 12" wide mudflaps.

I want to use your drill-less, but I need mudflaps longer/wider than the ones you show. Can you make them hang lower, or wider?

Because we make each pair of mudflaps here at our factory we are able to create new cut files based on the customer's needs. Custom lengths or widths may be accommodated for an extra fee. A few things to keep in mind when determining if you need customization are:

  • We recommend that the length be no closer than 6" to the ground. When you are closer, you may hit the mudflap on curbs and parking guards without realizing it. When you want them longer to protect a tow vehicle, remember, when you attach your trailer, your truck will squat a bit, giving your tow vehicle even more protection.
  • If looking at wider mudflaps make sure you have the room inside the wheel well to accommodate them without rubbing on suspension, or being blocked by the liner.
  • Custom size mudflaps are non returnable for anything other than defects, so make sure you measure correctly.
  • Since we cannot see your truck, our recommendations may only be based on what you describe to us.
    Custom orders need to be phoned in: 541-245-9148

Although our drill-less mudflaps do make the installation easier, you will still need some mechanical ability to install them. They come with all the directions and necessary hardware. We try to be available most every day to assist by phone when necessary so do not hesitate to phone if you run into difficulties.
