At a glance

Customer sentiment is overwhelmingly positive: buyers repeatedly praise Gatorback/SharpTruck mud flaps as premium, heavy‑duty, great-looking, vehicle-specific products that provide excellent protection, with standout customer service and fast shipping. The main negatives are high price, occasionally challenging/long installations (especially rears/dually), and periodic hardware/instructions/packaging issues or minor fitment quirks on certain trims/oversized tires.

What Customers Liked

  • Thick/heavy rubber, substantial weight, rugged/OTR-grade feel; holds up for years (5–10+ years reported), flexible in cold/snow, doesn’t “sail” at highway speed; strong brackets add stability.
  • Look “sharp,” “classy,” and OEM-like; logo/plate options (Ford/Chevy/Ram/AT4X/Z71/flags, etc.) get many compliments and add ‘pop’.
  • Many report perfect fit/‘like a glove,’ good tire coverage, options for offsets/oversized tires (e.g., offset versions preventing rubbing), adjustable positioning via slotted holes.
  • Significantly reduces mud/road salt/slush on running boards/steps and sides; helps prevent rock chips and protects trailers/RVs/boats; improves cleanliness on gravel/dirt roads and in winter conditions.
  • Often installs using factory holes and avoids drilling into metal body; videos and written instructions frequently cited as helpful; many install without removing wheels (fronts especially).
  • Consistently praised for responsive support, warranty replacements for tears/rips, quick resolution of shipping damage/wrong parts/missing items, and proactive communication/updates.
  • Fast delivery (often 2–5 days), accurate orders/fitment tools, good packaging noted by many; easy ordering and exchanges/returns.
  • Removable lower section on some models appreciated for added clearance during off-roading, then quick reinstall.

Things to Consider

  • Frequently described as expensive/‘hard pill to swallow’ (some citing $600–$1000+), though many still say it’s worth it.
  • Rears and dually setups often challenging/time-consuming; some recommend removing rear wheels, using a right-angle drill, clamps, or a helper; alignment can take time.
  • Some find written directions vague/confusing; hardware not clearly labeled (washers/spacers), left/right not distinguished, videos not always model-specific; “no-drill” marketing criticized when drilling in liners/plastic is still required.
  • Occasional missing screws/washers/clips/parts; mixed metric/SAE hardware complaints; plastic fasteners/clips stripping or pulling out; desire for stainless/black hardware and better washer/spacer labeling.
  • Some reports of rubbing with oversized tires/turning lock; minor misalignment of holes/templates; driver/passenger side fit differences; not perfect fit for some newer model years or with wheel-well liners/fender flares/steps.
  • Several note rear support brackets feel ‘necessary’ but are not always included; frustration at needing to add brackets separately or not being told upfront.
  • A few cases of brackets coming loose in transit causing scratches; damaged outer boxes; occasional wrong color/plate shipped.
  • Silver fasteners/washer heads stand out; some plates/finishes streak or rust (rare report of rust forming on logo); desire for thicker metal in certain kits.
  • Some note flaps hang low for off-road use; risk of tearing in deep snow, tall grass, or trail obstacles (though removability helps on some models).

The mounting/backing plates went in without a hitch. Then went to install the rubber flaps, watched videos and read directions. No holes in the flaps to match the plates. Very confusing, can't locate holes below with plates installed. They say if you buy them from Ford the flaps are predrilled for the 2017 Super Duty. Payed top dollar for these, should be done right. Not happy with them.
Gatorback mudflaps installation with custom brackets

The installation took several hours due to the instructions not being very clear or user friendly.  I consider myself very mechanically inclined and I had trouble interpreting the instructions. I suggest adding some photos along with the instructions showing how the brackets should look installed. The brackets fit OK, but not great. I had to do some amount of improvising to get things to fit. Aside from this, the installation went well and in the end, the mudflaps look great and the custom brackets provide very sturdy support for the heavy mudflaps. I'm very happy with the installation. In spite of the few issues that I had, I recommend these custom brackets to anybody installing rear mudflaps on a 2017 Ford F-350 dually.

Awesome product, mud flaps are only as good as the brackets that hold them in place. These brackets are as good as it gets at any price. Take the time to watch the tutorials, and installation is pretty straight forward. Installed with (21"X24") Ford Blue Oval flaps and the end result is A+
The flaps come pre-drilled for a universal installation, so when using the no drill brackets, you need to use the included templet to make the holes necessary for a custom installation. I used a uni-bit to drill holes, this also gives you some adjust-ability for a perfect fit.

These are by far the best flaps on the market. My brother bought a set for his 20 f-350 and loved them. I didn't look anywhere else. Easy to install and look great. Next is stainless for my running boards!

Care and Maintenance

To ensure your Gatorback Mud Flap Set remains in peak condition, it's important to follow a simple care and maintenance routine. With regular upkeep, your mud flaps will continue to provide excellent protection and maintain their great appearance for years to come.

  • Cleaning
    • Rubber Flaps: Regularly clean the rubber flaps with water and a mild detergent to remove dirt, mud, and road debris. Avoid using harsh chemicals that could damage the rubber. A soft-bristle brush or sponge works best for scrubbing away grime.
    • Stainless Steel Plates: To maintain the shine of the stainless steel plates, use a stainless steel cleaner or a mild soap solution. Avoid abrasive pads, as these can scratch the surface. Wipe the plates dry with a clean, soft cloth to prevent water spots.
  • Plate Maintenance
    • Periodic Polishing: To maintain the polished look of the stainless steel plates, polish them periodically using a non-abrasive metal polish. This will help remove any minor scuffs or marks and keep the plates looking like new.
  • Hardware Check
    • Mounting Brackets and Fasteners: Periodically inspect the mounting brackets and fasteners to ensure they remain securely in place. Tighten any loose fasteners as needed to maintain stability and prevent any movement while driving. Checking the brackets regularly will ensure that your mud flaps stay properly aligned and continue to offer the best protection.
  • Avoid Excessive Force
    • Avoid backing into obstacles that could damage the mud flaps, especially the rear flaps which are larger. The heavy-duty rubber is designed to be highly durable, but repeated force or impact can cause unnecessary wear.
  • Seasonal Considerations
    • Winter Care: During the winter, road salt can accumulate on the mud flaps and brackets. Be sure to rinse them frequently to prevent corrosion of the mounting hardware.

Warranty Information

Truck Hardware Gatorback mud flaps are backed by a limited lifetime warranty on the rubber portion. This warranty covers replacement due to normal wear and tear for the original owner. It does not cover damage resulting from abuse or extend to mounting hardware, brackets, or plates.

Terms

  • Virgin Rubber: High-quality, unprocessed rubber known for its durability and flexibility.
  • Cold-Formed 304 Stainless Steel: Stainless steel shaped without heat, improving strength, durability, and corrosion resistance.
