The Truck Hardware Gatorback Stainless Plate Mud Flaps rear dually pair combines serious protection with a polished 304 stainless steel plate for 2023-2027 Ford F-350 and F-450 Super Duty dual rear wheel (dually) trucks. 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 almost a 1/2" thick virgin rubber, mounted with custom fit brackets made for your exact truck, and backed by a lifetime warranty on the rubber. The result is a flap that hangs straight, stays put at highway speed, and keeps doing its job for the life of your truck.

These extra-wide 21" dually 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. The polished stainless steel plate adds a classic, refined look that stays bright and resists rust. Gatorback flaps are some of the highest quality, heaviest duty mud guards in the industry, they are test fit on every model year by Ford Accessories, 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 stays strong and flexible through heat, cold, rocks and gravel for years of reliable protection.
• Polished 304 stainless steel plates - Premium 304 stainless steel resists rust and corrosion, so the plates keep their polished, refined look through harsh weather and road salt.
• Custom fit, no drilling - Custom fit brackets and hardware made for the 2023-2027 F-350 and F-450 dually are included, and Ford Accessories test fits the flaps on each model year, so you get a precise, factory-quality fit with no holes drilled in your truck.
• Lifetime rubber warranty - If a flap comes off the truck or is damaged from normal wear and tear, Gatorback sends replacement rubber at no charge for as long as you own the truck.

Which Gatorback Is Right for Your Truck?

Gatorback mud flaps for the 2023-2027 Super Duty come in several versions. Use this quick guide to make sure you pick the right one:

• Rear pair or complete set - This listing is the rear dually pair only (2 flaps). Add a front pair for front wheel coverage. F-350 dually owners can also choose a complete dually set of 4, and F-450 owners can choose a complete F-450 set of 4.
• Single rear wheel vs. dually - This listing is for dual rear wheel (DRW) trucks, with extra-wide 21" rear flaps to cover both rear wheels. Single rear wheel (SRW) trucks need the standard 12" rear flaps.
• Lifted trucks or oversized tires - Running a single rear wheel Tremor, a lift or level kit, or oversized tires? Look at Gatorback Offset mud flaps, which use 1.5" offset nylon kickback brackets for extra tire clearance.
• Choosing a style - This version is the stainless steel plate style. This rear dually pair is also available in: plain rubber (no plate), black Ford oval, blue Ford oval, FX4, 6.7L Power Stroke, Platinum, Super Duty, black anodized Ford oval, black anodized Super Duty, American flag, black American flag, black anodized aluminum plate, black wrap Ford oval, F-350, gunmetal plate, black wrap FX4 and gunmetal Ford oval.

Features and Benefits

These flaps are made from heavy-duty, 1/2" thick virgin rubber, a high-quality, unrefined rubber that offers better strength, flexibility and wear resistance than recycled rubber. Each extra-wide 21" rear dually flap weighs 10 lbs, so the flaps stay in place instead of sailing at highway speed. These flaps are an extra-wide 21" to cover both dual rear wheels, with 11" of tire coverage from the bottom of the fender to the bottom of the flap. The 1/2" thick rubber keeps debris from passing through, so your truck stays cleaner longer with less damage to the body and step bars, and any trailer you are towing and other road users are better protected from kicked-up debris.

Each flap carries a polished 304 stainless steel plate. 304 stainless steel is a premium grade known for its excellent resistance to rust and corrosion, so the plates keep their polished, refined look even in harsh environments. The plate measures 17 1/4" x 5". You will appreciate the attention to detail in these flaps.

Fit is built in. Gatorback flaps are designed specifically for the 2023-2027 Ford F-350 and F-450 Super Duty dually, including XL, XLT, Lariat, King Ranch, Platinum and Limited trims, and Ford Accessories test fits the flaps on each model year to confirm fitment. The flaps mount to your truck's factory mounting locations with no body drilling, so your truck's body stays untouched and your resale value is protected. They also install flush to the inside of the wheel well, so they work alongside step bars, power boards and side steps without getting in the way. Gatorback mud flaps are proudly made in Canada.

Installation

Installation is simple, with no body drilling required. The flaps mount to your truck's factory existing mounting locations, and the custom fit brackets and hardware you need for a solid installation are included. Installation can be done with tools you already have at home and takes about 15 minutes per flap. The flaps install flush to the inside of the wheel well for a clean, factory look. Install videos and installation instructions are available so you can see the full process step by step before you start.

What's Included

• (2) Gatorback Stainless Plate 21" wide rear dually mud flaps (1 driver side, 1 passenger side)
• Custom fit brackets and mounting hardware for the 2023-2027 Ford F-350 and F-450 dually

Care & Maintenance

• Clean the rubber with a mild soap and water solution. Regular cleaning helps keep the rubber flexible and extends the life of the flaps.
• Avoid harsh chemicals and petroleum-based cleaners, which can break down rubber over time.
• Rinse thoroughly and let the flaps air dry for best results.
• Clean the stainless steel plates with a soft cloth and a mild detergent cleaner, or a stainless steel cleaner and polish, to maintain their shine. Use a cleaner with a pH between 4 and 9 to prevent discoloration, avoid abrasive materials and harsh chemicals that could scratch the surface, then rinse with clean water and dry with a soft cloth.
• Check the mounting hardware periodically and retighten if needed, especially after off-road or rough-road driving.
