At a glance

Overall sentiment is overwhelmingly positive: customers consistently describe Gatorback/SharpTruck mud flaps as premium, heavy-duty, great-looking products that provide excellent protection, with standout customer service and warranty support; the main negatives are high price and occasional installation/hardware/fitment frustrations.

What Customers Liked

Thick, heavy rubber with a substantial feel; durable, flexible in cold/snow/ice; doesn’t “sail” at highway speeds; plates/weights feel robust and can be replaced/swapped.
Significantly reduces rock chips, mud/salt spray, and slush on rocker panels, running boards/power steps, bumpers, trailers/RVs; many note cleaner sides and less debris noise on gravel roads.
Vehicle-specific fit often described as ‘like a glove’/OEM; finishes (chrome, gunmetal, black plates) and logo plates (Z71/AT4X/FX4/Ram/Ford/Chevy, flags, etc.) ‘make the truck pop’ and draw compliments.
Many report straightforward installs, especially after the first flap; helpful YouTube videos; slotted holes help leveling; adjustable stick-out; removable lower section appreciated for off-roading/clearance.
Fast shipping is frequently praised; responsive support for exchanges/mis-shipments/damaged parts; hassle-free warranty replacements (torn/ripped flaps or scratched plates) often sent quickly.

Things to Consider

Most common complaint: ‘pricey/overpriced’ (often $600–$1000 with brackets/plates). Some feel brackets/plates should be included at that price.
Installs can be time-consuming or awkward (especially rears/dually setups), sometimes requiring wheel removal, right-angle drill, extra hands, drilling into plastic liners, trimming liners/trim pieces, or drilling/slot-cutting templates.
Paper instructions sometimes lacking, confusing, or mismatched vs video; hardware bags not well-separated/labeled; left/right not always marked; templates/printer scaling issues; ‘no-drill’ marketing criticized when drilling plastic is required.
Occasional reports of cheap/fragile fasteners, plastic clips/nut inserts pulling out/stripping, mixed metric/SAE heads, silver hardware being visually noticeable, bracket thickness/material concerns (plastic/galvanized vs stainless), and clamp-on brackets potentially rubbing paint (suggest PPF/tape).
Some vehicles need hole elongation, bracket bending, or ‘gerry-rigging’; occasional rubbing with oversized tires/offset wheels; a few reports of mis-shipped parts (two rears), wrong plates/colors, missing washers/spacers/clips/screws, or shipping scuffs/scratches/damaged boxes.

2017 Ford Super Duty flaps

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.

2017 Ford F-450 King Ranch 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.

Excessive labor and ridiculous price.

I overpaid for these cuz they looked cool. Then found out after paying $300 for two rubber mud flaps that I then needed another $250 mounting brackets. I had them too long to return so I threw good money after bad and bought the brackets. The assembly instructions are horrible, had to watch you tube videos to assemble and install. Installation in my opinion is pretty extensive for a set of mud flaps. I’m not impressed at all and disgusted I ended up with $600 in rear mudflaps for a pickup truck. Definitely do not recommend.
