Guide to Chevy/GMC Mounting Brackets for Truck Hardware mud flaps
Why use mounting brackets on your Chevy/GMC truck?
While many drivers like to mount their flaps directly to the truck itself, there are different styles of mounting brackets available to strengthen the flap itself and provide better support. This will also result in a nice, straight flap that doesn’t curl, bend, roll, or tear over time. Highway haulers and off-roaders alike will find Truck Hardware’s Gatorback and Razorback bracket systems to be a simple install.
It’s important to note these are support brackets and the flaps still need to drilled into the wheel well and liner for added support. Options come in galvanized steel, aluminum, or stainless steel.
Chevrolet and GM trucks come in all sorts of colors and styles. No matter what your preference is, Truck Hardware mud flaps are geared to keep your paint job chip or knick free so your favorite ride glistens on the highway better than ever.

Universal Brackets
These brackets will fit any vehicle, unlike the custom flaps they might require some drilling to get them installed on the vehicle. You do have a few more options with the universal style.
Offset Brackets - These brackets will give you some more clearence from your tires. If your tires are oversized the offset brackets will keep the flap from rubbing on the tire. They are available in stainless steel and black powder coat, if black is more your style.
"L" Style Brackets - These are angled steel that you can attach to your truck frame. They come in a 12" size for standard flaps but they are also avaiable in a size for dually flaps. Don't be fooled by the simple design, these are effective brackets and will hold up as well as the flaps.
Brackets are specifically important for dually flaps, as they are very heavy and brackets help support their hefty anatomy.
No matter where your travels lead, and no matter how you get there, Truck Hardware mud flaps are manufactured to provide top-of-the-line protection with maximum function. Whether you drive a Ford F150, Dodge RAM, Chevy Silverado, or GMC Sierra, the selection of flaps is tailored to fit virtually any taste.
