The Truck Hardware Gatorback Rubber Mud Flaps F-450 set of 4 is the clean, no-logo choice for 2023-2027 Ford 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.
The 12" wide front flaps and extra-wide 21" rear 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. 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, 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.
- Stays put at highway speed - Each extra-wide 21" rear dually flap weighs 10 lbs, so the flaps hang straight instead of "sailing" (flapping up) in the wind, protecting your truck at every speed.
- Custom fit, no drilling - Custom fit brackets and hardware made for the 2023-2027 F-450 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:
- Made for the F-450 - This listing is a complete set of 4 for the F-450 (2 front, 2 rear dually). The F-450 uses its own front flaps, which differ from the F-250 and F-350 front flaps, so choose an F-450 specific set.
- 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.
- Plain rubber vs. plate styles - This version is plain rubber with no plate. This F-450 set of 4 is also available in: black Ford oval, blue Ford oval, Super Duty, stainless steel plate, black American flag, FX4, Platinum, black wrap FX4, black wrap Ford oval 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. The front flaps are a custom fit 12" wide with 12.5" of tire coverage below the fender, and the rear dually flaps are a custom fit 21" x 24" with 12" of coverage below the fender, for complete coverage of your F-450 that helps protect your truck, any trailer you are towing and other road users from kicked-up debris.
Fit is built in. Gatorback flaps are designed specifically for the 2023-2027 Ford 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. The front flaps take about 15 minutes per flap with basic tools, while the rear dually flaps take more time but do not need any specialty tools. Note that the F-450 front flaps require the truck's OEM splash guards. 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.

Care & Maintenance

This warranty covers rubber replacement (for example, tear-offs) for the lifetime of the product to the original owner. If a flap comes off the truck or is damaged due to normal wear and tear, let us know and we will send you a replacement piece of rubber at no charge.

Terms to Know
- Virgin rubber - High-quality rubber in its original, unrefined state, which is stronger and more durable than recycled rubber.
- No-drill installation - Mounting that uses your truck's factory mounting points, so no holes are drilled in the body.
- Tire coverage - How far the flap extends below the fender (12.5" front and 12" rear). More coverage means more protection.
