You just got back from a weekend run on a muddy two-track. The truck handled it fine. Your rocker panels did not. A thick stripe of red clay runs from the front fender to the rear door. The paint behind the rear wheels looks like a Jackson Pollock. That is what happens when you run 35s under widened flares with nothing catching the spray. This guide breaks down what actually fits by generation, what to pay, and how to bolt it on in a driveway.
The F-150 Raptor runs wider fender flares and bigger tires than any standard F-150, so regular F-150 mud flaps will not fit. You need Raptor-specific, vehicle-specific flaps sized for the 315/70R17 (Gen 2) or 37-inch (Gen 3 Performance Package) tire footprint. Bolt-on kits exist for 2017-2020 Gen 2 and 2021-2024 Gen 3 bodies. Budget $40 to $120 per set. Install takes about 30 minutes with hand tools.
Why the Raptor Needs Its Own Mud Flaps
Park a Raptor next to a standard XLT and stand behind the rear tire. The Raptor's body is roughly 6 inches wider at the fenders. That gap is filled by factory flared bodywork. The tire sits out closer to the edge of that flare than any other F-150 trim.
That geometry is why universal F-150 flaps look wrong the second you bolt them on. The flap hangs inside the flare line. Mud, rocks, and slush arc past it. Everything you tried to block still lands on your rocker.
Then you have the tires. Gen 2 models ship with 315/70R17 BFG All-Terrains, roughly 35 inches tall. Order a Gen 3 with the 37 Performance Package and Ford stuffs a genuine 37 under there. That tire throws debris further, faster, and higher than the 275s on a regular F-150. Ask anyone with a lifted truck: bigger tire means bigger spray radius and bigger flap needed.
A Raptor-specific flap is cut to hang below the flare. It is wide enough to catch the tire's full arc. It is shaped to clear the plastic body cladding without rubbing. This is not a marketing distinction. It is the only shape that works.
Gen 2 vs Gen 3 Raptor: Body Differences That Affect Fitment
Gen 2 and Gen 3 look similar in a parking lot. They are not the same truck under the flares.
2017-2020 Gen 2 Raptor Dimensions
Gen 2 rolled out in 2017 with the 3.5L twin-turbo EcoBoost, aluminum body, and 6-inch-wider front fenders versus a standard F-150. Wheel well openings are shaped for the 35-inch BFG KO2. Rear flap mounting points sit inside the bed side, using two factory holes plus a plastic clip.
SuperCab and SuperCrew share the same rear flap dimensions on Gen 2. Front flaps are identical across cab configs. If you are shopping used and want a deeper look at year-by-year cabin changes, F-150 SuperCab interior upgrades by year walks through what changed inside those trucks.
2021-2024 Gen 3 Raptor Dimensions
Gen 3 arrived for 2021 with a redesigned front end, a five-link rear suspension, and the option box that changes everything: the 37 Performance Package. Standard Gen 3 wears 35s. Check the box and you get 37s, wider fenders, extended flares, and different mounting geometry for the rear flap.
That means a mud flap kit that fits a 35-inch Gen 3 will not always fit a 37-inch Gen 3. Look for kits that list the Performance Package by name. Ford's own build sheet on the Ford spec page confirms which flare width your VIN carries.
| Generation | Years | Standard Tire | Optional Tire | Front Flare Width vs F-150 |
|---|---|---|---|---|
| Gen 2 | 2017-2020 | 315/70R17 (~35") | None | +6.0 in |
| Gen 3 | 2021-2024 | 315/70R17 (~35") | 37x12.5R17 | +6.0 in / +7.2 in with 37 PP |
Cross-shopping between generations? Do not assume the flaps swap. They do not.
Types of Mud Flaps That Fit the F-150 Raptor
“Great communication. Informative installation videos. Durable seat covers and steering wheel wrap. Nice upgrade from the flimsy, worn-out covers I had.”
“They feel super comfortable and were easy to install! Can't wait to get my custom rear seat covers!”
“There's not much to say — you simply have to buy them yourself because they truly speak for themselves. From the online purchase to the fit, top notch.”
“I couldn't have been more pleased with this product!”
“Great fit, great looks, great quality. Exactly what I wanted for my truck.”
Three shapes dominate the Raptor market. Each has a use case.
OEM-Style Bolt-On Flaps
These are the ones Ford's parts counter will sell you. They use every factory hole and sit flush with the flare. They look like they came on the truck. No drilling. No cutting. You lose about $30 to $50 in price versus aftermarket because you are paying for the badge and the paint-matched top edge. Owners who trailer the truck to shows love them. Owners who wheel hard sometimes wish they were tougher.
Flexible Rubber Flaps
Rubber flexes. That matters when you rock-crawl or hit a curb backing into a launch ramp. A rigid flap will crack at the mounting tab. Rubber will fold, bounce back, and keep working. Rally Armor is the reference brand here. Their 2017-2020 kit shows up in half the Reddit threads for a reason. Downside: some rubber flaps sag in Arizona summer heat after a few years.
Molded Thermoplastic Flaps
Husky Liners and Bushwacker sit here. Molded plastic holds its shape in the sun and resists UV fade. It looks cleaner than rubber for a daily driver. The tradeoff is stiffness. Take a hard hit off-road and the mounting point can crack. Fine for pavement and gravel, less ideal for a truck that lives on trails.
You will also see "universal cut-to-fit" options advertised as Raptor-compatible. Skip them. The Raptor's flare curve is not a straight edge. A scissor job on a $30 flap looks like a scissor job on a $30 flap.
Top Made-to-Fit Mud Flap Options for the Raptor
Here is what shows up on Raptor forums when people actually put miles on their choice.
| Brand | Fits | Price Range | Hardware | Best For |
|---|---|---|---|---|
| Ford OEM | 2017-2024 (specify Gen and PP) | $95-$120 | Included | Clean stock look |
| Husky Liners Molded | 2017-2020 Gen 2 / 2021-2024 Gen 3 | $85-$110 | Included | Daily driver, all-weather |
| Rally Armor UR Basic/Black | 2017-2020, 2021-2024 | $150-$180/set | Included | Off-road, urethane flex |
| Rokblokz Original | 2017-2024 (37 PP variant available) | $170-$210/set | Included | Heavy trail use |
| Truck Hardware Gatorback | Gen 3, Raptor R specific | $130-$160 | Included | Anodized style plate |
| Bushwacker | 2017-2020 mainly | $40-$70/pair | Sold separately sometimes | Budget, stock-tire trucks |
The 37 Performance Package throws a wrench in this list. Rokblokz and Rally Armor both offer 37-specific SKUs. Husky's Gen 3 kit works with 35s and most 37s, but confirm before you order. A forum user put it best after cracking stiff plastic options on a Utah trail run: buy once, cry once, and get the urethane if you actually wheel the truck.
Hardware matters. Rokblokz and Rally Armor ship stainless bolts and backing plates. Some cheaper kits give you Phillips-head zinc screws that will rust to orange in one winter. Not worth the $30 you saved.
How to Install Raptor Mud Flaps in Under 30 Minutes
Grab a trim removal tool, an 8mm socket, a 10mm socket, and a T25 Torx. That covers 95% of Raptor mud flap kits.
Front flaps first. Open the door and look inside the fender well. You will see two factory holes with plastic push-clips. Pop those out with the trim tool. The flap sandwiches between the flare and the fender liner. Hand-thread the bolts first, then snug them with the 8mm. Do not power-tool this. Plastic mounting tabs strip fast. Once they crack, you are shopping for a new flap.
Rears are similar but tighter to reach. SuperCrew rear flaps sit forward of the tire. On Gen 3 you may need to pull one plastic pin from inside the bed side to line up the bracket. Test-fit before you torque anything down. Owners on the Ford truck forums note the passenger-side rear on 2021+ trucks lines up about 3mm off if you install it with the wheel turned. Straighten the wheel first.
Torque spec is finger-tight plus a quarter turn. That is it. If the flap wiggles at speed, add a lock washer. Do not crank harder. If you see a factory hole that already has a bolt in it, that bolt is the one you need to remove and reuse. Do not add hardware where hardware already exists.
Keeping the Rest of Your Raptor Interior Just as Clean
Here is what nobody tells you when you install mud flaps: you fixed the outside, but the inside is still where the mud ends up. You climb out of the driver's seat after a trail run, boots caked. You grind clay into that bolstered sport seat every time you slide out.
The Raptor's factory sport seats are more heavily bolstered than any other F-150 trim. Those bolsters are the first thing to wear because you rub against them every entry and exit. Add a shedding dog in the back or a kid in muddy soccer cleats and the rear bench turns into a lost cause by year three.
This is where custom seat covers do the same job for your interior that mud flaps do for your paint. Tailored, OEM-styled covers cut for the Raptor's exact seat shape, airbag-safe, installed in under an hour. Half the price of a dealership reupholster.
If you want the full breakdown for your truck, custom seat covers for trucks lists the F-150 fitments including trim-specific dimensions for the Raptor's sport buckets.
Best Years to Buy a Used F-150 Raptor (and What to Check)
Early 2017 Gen 2s had a rough first year with the 10-speed transmission. Shift hunting, hard 3-2 downshifts, and a couple of TSBs. Ford cleaned most of that up by mid-2018 with reflashes. If you are shopping Gen 2, aim for 2019 or 2020. Both years benefit from the transmission software updates. The 2019 refresh added the Trail Control system.
Gen 3 is still young enough that data is thin, but 2022 and 2023 model years look strong. The 37 Performance Package is worth the money if you actually run trails. If it lives on pavement, save the cash and stick with the 35-inch tire.
Resale is the Raptor's calling card. These trucks routinely hold above 70% of MSRP two years in. Limited build numbers and a cult following do that. The F-150 Limited interior upgrade ideas piece walks through the sister-trim market if you are deciding between a loaded Limited and a used Raptor.
Check the front suspension bushings and the rear shock reservoirs on any used Raptor. Those Fox internal bypasses can leak after 60,000 hard miles.
Other Accessories That Pair Well With Raptor Mud Flaps
Once you have got the mud flaps sorted, the natural next moves are rock sliders or running boards for the rockers. A spray-in or drop-in bed liner saves the bed floor. A set of floor liners gives the mud you track in somewhere to sit besides your carpet.
Interior protection follows the same logic. If you like the off-road look inside as well as out, exact fit leather seat covers show what a full custom set looks like on a Ford off-road platform. Same construction, same OEM-styled cut, sized to the vehicle you actually own.
Frequently Asked Questions
Q: What year F-150 Raptor should I avoid?
Skip the very early 2017 Gen 2 build if you can. Those trucks had the roughest 10-speed transmission behavior before Ford issued the software fix. Shift hunting between 4 and 5, harsh 3-2 downshifts, and a few reports of torque converter shudder. By late 2018 most of that was addressed via reflash. The 2019 and 2020 Gen 2 model years are the sweet spot for reliability, price, and available warranty.
Q: Does an F-150 Raptor hold its value?
Yes, better than almost any other half-ton truck on the market. Limited production, a strong off-road reputation, and steady demand keep used prices high. Two-year-old Raptors regularly sell above 70% of original MSRP. Clean low-mileage Gen 2s from 2019 and 2020 sometimes trade for nearly what they cost new. Standard F-150 trims drop faster. The Raptor badge is a real resale asset, not a marketing story.
Q: What are the best accessories for an F-150 Raptor?
Made-to-fit mud flaps sized for the flare, a quality bed liner or bed mat, rock sliders if you wheel it, and tailored seat covers to protect the sport buckets. Floor liners come next because the Raptor's factory carpet is thin. LED off-road lighting is popular but only useful if you actually drive at night. Skip anything cosmetic that adds weight without function. The truck already looks the part from the factory.
Q: Is a Ford Raptor faster than a Ram TRX?
Straight-line, no. The Ram TRX runs a 702-hp supercharged Hemi V8 and clears 60 mph in about 3.7 seconds. The standard Gen 3 Raptor with the 3.5L EcoBoost puts down 450 hp and runs mid-5s. The Raptor R closes the gap with 700 hp from a supercharged V8 of its own and gets close. But the Raptor is tuned for high-speed desert running and trail agility, not drag racing. Different mission.
Q: Will standard F-150 mud flaps fit a Raptor?
No, and it is not close. The Raptor's fender flares sit roughly 6 inches wider than a standard F-150. The tires push out to nearly the edge of that flare. A regular F-150 flap mounts inboard and leaves a wide gap where spray shoots past. You get almost no protection for the rocker panel or the paint behind the rear wheel. Buy Raptor-specific flaps, or do not bother.
