FIT — Mud Flaps feature standard mounting holes for easy installation. Standard mounting holes are oval in shape, four (4) across, 3/8″ x 3/4″ in size and located 1″ from the top and sides of the flap, with 6-1/8″ spacing between holes. No drilling necessary.

Product FAQs

Is There An Order Minimum?

Orders for fewer than 10 pairs are charged an “Under Minimum Fee” of $5/pair. Orders are processed on a first-come-first-served basis, with absolutely no bias toward larger orders. Our #1 concern is customer satisfaction regardless of the size of your order.

Can The Text Say Whatever I Want?

We reserve the right to refuse any request due to the inappropriateness of the text, including – but not limited to – sexually suggestive or profane verbiage. Read our Terms and Conditions if you believe this FAQ applies to you.

Do You Offer Stock Lowercase Letters?

No. In-House Letters are all uppercase. The use of lowercase letters will require the purchase of a magnesium tooling die, which is an additional fee.

What Is A ‘DIe Charge’ & How Much Is It?

The ‘Die Charge’ is billed out anytime magnesium die casting is needed to produce custom logos, graphics or typefaces. The amount of the ‘Die Charge’ is based on the total number of square inches of the design. USA Flap shares the cost to produce these custom dies, and will retain possession of it should you wish to re-order your custom Mudflaps.

What Is The Maximum Number Of Text Rows I Can Use?

The answer ultimately depends on the size of the Mudflap, and whether or not you mix-and-match 2″, 3″ and 4″ letters. However, assuming equal size letters and 1″ spacing between rows, you can expect to fit on a 24″ x 30″ Poly/Rubber Mud Flap:

— 2″ Arial Letters: Maximum of 8 text rows
— 3″ Arial Letters: Maximum of 6 text rows
— 4″ Arial Letters: Maximum of 4 text rows

What Does It Cost To Add Stock Graphics To My Stock Letter Mudflaps?

Many customers are surprised to learn that USA Flap does not charge graphic design or setup fees if you choose to add in-house graphics, so long as the color is the same as the text font color. If you would like the color of the graphic to be different than the text, the cost is $1.25 per additional color, per pair.
