Gatorback Plate Finishes

Here are the different plate finishines

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.

Install went fine.  Used the diagram supplied and the install Videos.  The no-drill assy is sturdy, rigid, and secure compared to several other's I've had/tried in my past.  Went onto the TREMOR F350 w/o any issues.    The Carb-grey with the gunmetal flaps looks really amazing.   I'll bump to 5 once I run them over winter in rural MI and dirt, snow and slush for 6 Mos. :-)

These made a hard install very easy. I was wondering how I was going to make these mud flaps work ,until I found these brackets on sharptruck.com.
Curving of flap in the picture is due to improper storage of flaps and in no way shape or form related to the brackets.

Crafted to endure the toughest conditions, these mud flaps offer extensive coverage while adding a unique, rugged look to your vehicle. Featuring gunmetal stainless steel plates, this set combines an aggressive style with optimal functionality. With 12-inch wide heavy-duty front rubber flaps and 21-inch wide rear rubber flaps, these mud flaps deliver 9 inches of tire coverage for the front and 10.5 inches for the rear, ensuring comprehensive defense against mud, gravel, and road debris.

Constructed from 1/2" thick virgin rubber, these mud flaps offer outstanding flexibility and durability, making them ideal for all weather and driving conditions. The gunmetal stainless steel plates measure 10 1/4" x 5" on the front flaps and 17 1/4" x 5" on the rear flaps, adding a striking and resilient finish to your truck.

Key Features

  • Heavy-Duty Rubber Construction: Made from 1/2" thick virgin rubber, these mud flaps are engineered for maximum durability and resistance to cracking or warping.
  • Enhanced Tire Coverage: 9 inches of front tire coverage and 10.5 inches for the rear, providing optimal protection against road spray and debris.

  • Gunmetal Stainless Steel Plates: The gunmetal stainless steel plates add a bold, aggressive look, enhancing the overall style of your truck.

Installation

Front Flap Installation: The front mud flaps mount directly to the lip of the wheel well using self-tapping screws and existing factory fasteners where applicable. The installation process requires only basic tools and is straightforward. Ensure 1/2" of clearance between the tire and the wheel well to accommodate the thickness of the flaps. The front flaps are designed to install flush with the wheel well, integrating seamlessly with other accessories such as side steps or power boards.

Rear Flap Installation: The rear flaps attach using custom-fit rear support brackets and self-tapping screws, ensuring they stay tightly in place. This installation method prevents the mud flaps from flapping into the tires, even during challenging driving conditions or off-road use.

Care & Maintenance

To keep your Gatorback Gunmetal Plate Dually Mud Flaps in optimal condition:
