  • At a glance

    Customer sentiment is overwhelmingly positive: reviewers praise Gatorback/SharpTruck mud flaps as premium, heavy-duty, great-looking protection that fits well and performs in mud/snow/gravel, with standout customer service. The most common negatives are high price and installation/fitment frustrations (sometimes requiring drilling, extra tools, or bracket add-ons), plus occasional missing/damaged hardware or shipping scuffs.

    What Customers Liked

    • Consistently described as thick, heavy-duty rubber with substantial weight/plates; durable, flexible in cold weather (snow/ice), doesn’t ‘sail’ at highway speed; many report years of use with minimal wear.
    • Strong reduction in rock chips, mud/salt spray, and debris on paint, running boards/power steps, bumpers, trailers/RVs/boats; better coverage than OEM or molded plastic flaps; wide/long options praised for gravel roads and towing.
    • Many report perfect/direct fit using factory holes, adjustable in/out positioning, good clearance with certain tire sizes (including some 35" setups); brackets/caps/finishing pieces create an OEM-like look.
    • Flaps ‘look sharp’/classy and make trucks stand out; metal logo/weight plates (Ford/Chevy/Ram/GMC/trim packages, flags, black plate/gunmetal/chrome options) are a major purchase driver; replaceable plate concept appreciated.
    • When it goes well, installs are quick (often 30–60 minutes, sometimes without removing wheels); YouTube videos and templates frequently called helpful.
    • Repeated praise for fast shipping, responsive support, easy exchanges, and quick warranty replacements (torn flaps, scratched/damaged plates, wrong items, missing parts), often shipped same day.

    Things to Consider

    • Most frequent complaint: ‘pricey/expensive’ (often $600–$1,000); some feel forced into buying additional bracket kits or plates, and a few call it overpaid/poor value.
    • Install can be time-consuming or frustrating on some vehicles/trim levels (wheel well liners, rock rails, factory flaps, dually setups); may require removing wheels, a right-angle drill, cutting slots, drilling into liners/plastic, aligning templates, or two-person help.
    • Multiple reviewers note ‘no-drill’ is misleading—often still requires drilling into plastic liners or flaps/templates (even if not into metal body).
    • Complaints about unclear/mismatched paper instructions vs video, too many similar washers in one bag, lack of labeling left/right, metric vs SAE hardware, bolt length/head size, and desire for black hardware instead of visible silver fasteners.
    • Occasional rubbing with oversized tires/offset wheels; some report holes not lining up, needing to elongate/drill new holes, bracket angles not matching, or flaps sitting too low for off-road use (ground clearance concerns).
    • Reports of scuffed/scratched plates from transit, damaged boxes, missing spacers/washers/clips/screws, wrong parts (e.g., two rear sets), and occasional hardware quality concerns (plastic nut inserts/clips pulling out, flimsy brackets in some kits).
    • A few mentions of rear flaps tearing at contour points over years, concern about clamps rubbing paint (suggest PPF), and metal-on-metal clamp/rust worries in salted winter climates.

    I really like how heavy the flaps are and they actually fit  great!
    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.

    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!
