Step by Step Instructions

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.

If you buy the gator back mud flaps you better go ahead and buy these brackets. The mud flaps are very heavy and these brackets support the mud flaps properly. They fit perfect on my 2019 Ram 3500 DRW.

The accessory brackets are a must if you are going to install the gator back flaps, the top bracket requires some thinking to get installed a real challenge for that bracket, after the upper bracket is installed all else goes pretty good. These Gator Backs look great on my truck and are of excellent quality.

Nice product but hardware kit could be better

Mounting Brackets are good quality and designed well. I gave it 4 Stars because the hardware kit
provided is adequate but I don’t understand why
you would use stainless steel split lock washers on a  stainless steel flat washer. Besides the extra effort to put it all together when you are contorting your body under the truck. I would recommend using stainless steel nylock nuts and save yourself time and effort installing the mud flaps with this bracket kit.

The brackets and instructions don’t distinguish which one is left or right.  Also be prepared to get frustrated and try several methods to finally get them in.  If you have long arms or happen to have a truck lift you will probably make easy work of it.  In addition the screws that come with it are fragile so be easy on tightening.  They break with little torque.
