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.

Really like the color and lettering on bright stainless steal . They are heavy duty to help keep rocks down from chipping the paint .

These brackets fit my 2017 Denali perfectly!

These were easy to use and fit perfectly. I painted mine black with some krylon primer flat paint. I mounted the flaps to the bracket, then the bracket to the wheel well, then was able to drill from the back side of the wheel well from under the truck to mount the additional self-tapping screws without removing the tires.

Easy to install brackets!

Instructions were clear, concise and easy to follow. The brackets provide an easy way to hang the mud flaps from existing OEM fender liner mount screw while aligning and securing the rest of the mount screws. Thanks for the assist!
