The Truck Hardware Gatorback Bucking Bronco Mud Flaps set of 4 combines serious protection with the officially licensed Bucking Bronco logo on a black wrap 304 stainless steel plate for 2021-2027 Ford Bronco models (excluding Bronco Raptor) without rock rails, including Broncos with removable hoop steps. 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 cut from heavy-duty, 1/2" thick premium rubber and mounted on a durable nylon upper bracket with a 1.5" kickback for extra tire clearance, and a sliding channel lets you remove the rubber when you need it. The result is a flap built for the trail that keeps doing its job for the life of your Bronco.
These 12.5" wide flaps protect your Bronco from rocks, mud, gravel, snow, slush and road debris, so you will see your Bronco staying cleaner longer, less mess on your rocker panels and doors, and fewer rock chips in the paint. The Bronco logo plate gives your Bronco a distinctive, bold appearance that is ready for any trail. 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.
- Officially licensed Bucking Bronco logo, black wrap - The logo is die-stamped into a 304 stainless steel plate with a black wrap finish for a bold, blacked-out look that resists rust and corrosion.
- 1.5" offset nylon kickback brackets - The durable nylon upper brackets (1.5" kickback) add tire clearance and resist fading, chipping and cracking, and a sliding channel lets you remove the rubber when needed.
- 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.

Care & Maintenance
- Clean the rubber regularly with a mild soap and water solution to remove dirt, mud and grime. Regular cleaning helps keep the rubber flexible and extends the life of the flaps.

- Wipe down the nylon brackets with a damp cloth and a mild pH-balanced soap to keep them in top condition.
- Clean the black wrap plates with a soft cloth and a stainless steel cleaner, or a mild soap and water solution, to maintain their polished appearance. For tougher stains or minor surface corrosion, use a stainless steel cleaner made for automotive use. Avoid abrasive materials that could scratch the surface or damage the finish, and dry the plates thoroughly to prevent water spots.
- Check the mounting hardware periodically and retighten if needed, especially after off-road or rough-road driving.
