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.

Brackets were a huge waste of time.

The flaps themselves are great. Excellent quality rubber. The problem with this "kit" was the brackets for the rear flaps and instructions for them. Since the brackets are galvanized, I took the time to spray them with a rubber undercoating spray for added weather resistance. The instructions that are shown here are different and incomplete from the  ones included with the flaps. There are overlays that you line up to make mounting holes in the flaps. Problem is the markings did not line up with the holes on the truck. Marking and drilling holes, then cutting out slots in the thick rubber was a job in itself, then not lining up and having to modify them was a real hassle. The front flaps went on easily (no brackets). I was a helicopter mechanic in the Army for 7 years, I'm no beginner at turning wrenches. Save yourself some money and hassle and skip getting the brackets. The fronts I would give a 5 star rating, but the extra hassle brought my overall rating down.
Best mud flaps ever bought .

Are the gator back mud flaps stainless like I mean good stainless I live in mn so road salt here is a big concern. I would not want to buy something that will just rust in a year. Thank you.

- David on 1/29/2018

These are made of 304 stainless steel. This metal will not rust. The flaps were tested and designed in Canada so they will hold up to Minnesota winters.

Made from 12-inch wide heavy-duty premium virgin rubber, these flaps provide full tire coverage and exceptional durability to protect your vehicle from rocks, mud, and other road debris. Whether you're driving through the city or venturing off-road, these mud flaps ensure your truck remains protected and looking sharp.

The Gatorback mud flaps feature the iconic Z71 logo, officially licensed for authenticity, die-stamped into a stainless steel plate with a hand-applied vinyl overlay.

Installation

Front Flap Installation: The front mud flaps attach directly to the lip of the wheel well using self-tapping screws, and existing factory fasteners can also be used if available. Installation is straightforward and requires only basic tools. Be sure to allow at least 1/2" of clearance between the tire and the wheel well to accommodate the flap's thickness. The front flaps install flush with the wheel well, allowing for seamless integration with accessories like step bars, power boards, or side steps.

Rear Flap Installation: The rear flaps are secured using custom-fit rear support brackets along with one or two self-tapping screws to hold them tightly against the wheel well. This method ensures the flaps stay in place and do not flap into the tires, even under challenging driving conditions.

Key Features

  • Premium Virgin Rubber: Made from UV-resistant virgin rubber for superior durability, flexibility, and resistance to cracking—ideal for harsh environments.
