At a glance

Overall sentiment is strongly positive: buyers consistently describe Gatorback/SharpTruck mud flaps as premium, heavy‑duty, great-looking, and highly effective at stopping rocks/mud/snow from hitting paint, steps, and trailers. The main reservations are the high price and occasional installation/fitment or hardware/packaging issues, which are often mitigated by responsive customer service and strong warranty support.

What Customers Liked

  • Thick, heavy rubber with substantial weight plates; feels “OTR/semi-truck grade,” doesn’t flap at highway speeds, flexible in cold weather, holds up through winters, gravel roads, mud, and years of use; many repeat buyers across multiple trucks.
  • Significantly reduces rock chips, road debris, mud/salt spray on paint, rocker panels, running boards/power steps, cameras, and keeps trailers/5th wheels/RVs cleaner and protected; coverage often better than OEM or plastic splash guards.
  • Looks “sharp,” classy, and truck-specific; logo/plate options (Z71, AT4X, Ford, Ram, Duramax, flags, black/satin/gunmetal/chrome) get compliments and help the truck stand out; finishing caps appreciated.
  • Many report perfect/vehicle-specific fit with factory-hole mounting, adjustable in/out positioning, good clearance with stock tires, and compatibility with certain trims/fender flares when configured correctly.
  • Generally described as straightforward with the right tools; helpful YouTube videos; bracket kits (especially rear/dually) add stability and make alignment easier; ability to install without removing wheels on some vehicles.
  • Frequent praise for fast shipping, responsive support, quick exchanges for wrong parts, replacement parts/plates/flaps shipped rapidly, and hassle-free warranty (including tears/rips or shipping damage).
  • Replaceable plates; removable lower section on some models for off-road clearance; ability to adjust flap stick-out; some like drilling only into plastic liner (not body).

Things to Consider

  • Most common complaint; many call them expensive/overpriced (often $600–$1000+), sometimes compounded by needing separate bracket kits/plates; some say alternatives may be “good enough” for less.
  • Mixed experiences: some installs are quick, others take hours—especially rear/dually, with wheel-well liners, rock rails/steps, or limited access; right-angle drill and/or removing rear wheels often recommended; alignment can be finicky.
  • Paper instructions sometimes vague, lacking steps, inconsistent with videos, or confusing (hardware ID, left/right orientation, templates, washer placement); requests for better labeling, templates, and model-specific videos.
  • Occasional reports of holes not lining up, needing to drill/elongate slots, bend/trim brackets, trim liners/trim pieces, or create homemade brackets; some rubbing with oversized tires/offset wheels; a few cases of poor fit on specific trims/years.
  • Multiple reviewers note drilling is still required (usually into plastic liner or flap), so ‘no-drill’ feels misleading in some kits.
  • Some dislike plastic clips/nut inserts pulling out/stripping, mixed metric/SAE hardware, bolt length issues, flimsy/galvanized or plastic brackets at high price, silver hardware visible (wish black), occasional missing/mismatched hardware or parts.
  • Some flaps/plates arrived scuffed/scratched or boxes damaged; brackets loosening in transit; a few wrong items shipped or missing pieces (spacers/washers/clips), though support often resolves quickly.
  • Some note low ground clearance depending on model/height; concerns about snagging in deep snow, tall grass, or off-road obstacles; some wish flaps were longer/shorter depending on use.
  • Plate finish can streak/stain (e.g., gunmetal), color/gloss differs from expectations, logos not level in a few cases, and some wish flaps came pre-slotted/pre-drilled for easier install.
