The Truck Hardware Gatorback Rubber Mud Flaps offset set of 4 is the clean, no-logo choice for 2021-2027 Ford F-150 trucks, including Tremor models, running oversized tires or small lift and leveling kits. Gatorback is a premium mud flap built to a higher standard than typical aftermarket flaps, and it shows the moment you pick one up. Each flap is made from heavy-duty virgin rubber, mounted on custom fit 1.5" offset nylon kickback brackets for extra tire clearance, and backed by a lifetime warranty on the rubber. The result is a flap that clears bigger tires and lifted suspensions and keeps doing its job for the life of your truck.
These 12.5" wide flaps protect your truck from rocks, mud, gravel, snow and road debris, so you will see your truck staying cleaner longer, less junk on your step bars, and fewer rock chips in the paint. This version is plain black rubber with no plate, a tough, understated look for owners who want serious protection without extra styling. Gatorback flaps are some of the highest quality, heaviest duty mud guards in the industry, and they are proudly made in Canada. If you are looking for mud flaps you buy once and never think about again, this is them.
Key Features
- Heavy-duty 1/2" thick virgin rubber - Many aftermarket flaps use thinner, recycled rubber that can curl, sag or tear over time. Gatorbacks use thick, premium virgin rubber that resists cracking and stays strong and flexible through heat, cold, rocks and gravel for years of reliable protection.
- 1.5" offset kickback brackets - Nylon and fiberglass composite kickback brackets set the flaps back 1.5" for extra tire clearance, so they fit every 2021-2027 F-150 trim including Tremor and work with lift or level kits and oversized tires, with no body drilling.
- Removable rubber, black oxide hardware - A sliding channel lets you remove the rubber lower section for extra ground clearance or easy cleaning, and all fasteners are black oxide stainless steel for corrosion resistance and a clean, blacked-out look.
- Lifetime rubber warranty - The rubber is covered for life against tears or damage under normal use, and the nylon brackets carry a 1-year warranty against manufacturing defects.
Which Gatorback Is Right for Your Truck?
Gatorback mud flaps for the 2021-2027 Ford F-150 come in several versions. Use this quick guide to make sure you pick the right one:

Features and Benefits
These flaps are made from heavy-duty, 1/2" thick virgin rubber, a high-quality rubber that has not been recycled, offering better strength, flexibility and wear resistance than reclaimed rubber. The thick rubber stays flexible, resists cracking and holds its shape while it deflects debris. The 12.5" wide flaps give you 9.75" of tire coverage up front and 10.5" in the rear, measured from the bottom of the fender to the bottom of the flap. A sliding channel design allows you to remove the rubber lower section for added ground clearance when needed.
Fit is built in. These offset flaps are custom designed for 2021-2027 Ford F-150 trucks, including XL, XLT, STX, Lariat, King Ranch, Platinum and Tremor trims. The upper brackets are made from a nylon and fiberglass composite that resists fading and chipping while providing flexibility and UV resistance, and their 1.5" kickback adds tire clearance for oversized tires and lift or leveling kits. All included hardware is black oxide stainless steel for corrosion resistance and a cohesive look. The flaps mount to your truck's factory mounting points with no body drilling and work with step bars, power boards and side steps. Note that they will NOT fit trucks with aftermarket fender flares. Gatorback mud flaps are proudly made in Canada.
Installation
Installation is simple, with no body drilling required. The custom fit nylon kickback brackets align with your truck's factory mounting points, and the black oxide stainless steel hardware you need for a secure installation is included. Installation can be done with standard tools you already have at home. Each flap features a sliding channel, so the rubber lower section can be removed easily when you need extra ground clearance. Install videos and installation instructions are available so you can see the full process step by step before you start.

Terms to Know
