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.

Bracket GB755006 for 2014 F150

I used rear bracket no. GB755006 for my gatorback mud flaps on my 2014 Ford F150.  Extremely easy to install (remove the tires) and solid once they're on.  Hardware lined up well.  Not a lot of play for adjustment, but didn't really need it.  Great product for '11-'14 Fords.

The orginal brackets are looked corrored and rusty  after 3+ years. so I decided to replace with a set of new brackets.  It's nice to be able get just the brackets and not having to buy mud flaps again. I'm hopng these last longer then the first set. They are a direct replacement, so intallation was super easy.

Specifically designed for single rear wheel F-150 pickup trucks, these mud flaps offer superior protection against road debris while adding a custom, rugged look to your vehicle. Featuring the officially licensed FX4 logo die-stamped onto a stainless steel plate with a titanium darkened finish, these mud flaps perfectly combine functionality with distinctive styling.

The Gatorback Mud Flaps are crafted from 1/2" thick heavy-duty virgin rubber, providing unmatched durability, flexibility, and resistance to cracking and fading. Virgin rubber ensures exceptional quality, making these mud flaps capable of handling extreme conditions while maintaining their appearance for years. The 12" wide mud flaps offer excellent tire coverage, with 9" of tire coverage in the front and 10.5" in the rear, keeping your truck cleaner and minimizing damage from flying debris. Whether you're navigating tough off-road trails or cruising through city streets, these mud flaps will protect your truck and enhance its look.

Key Features

  • Heavy-Duty Virgin Rubber Construction: Made from 1/2" thick virgin rubber, offering superior flexibility, resilience, and resistance to harsh weather conditions.
  • Official FX4 Logo with Gunmetal Finish: The FX4 logo is officially licensed through Ford Accessories, die-stamped onto a stainless steel plate with a titanium darkened finish for added style.
  • Full Tire Coverage: The front mud flaps provide 9" of tire coverage, while the rear flaps cover 10.5", offering maximum protection from rocks, mud, snow, and gravel.
  • Custom Fit Rear Support Brackets: The set includes custom-fit rear support brackets (GB755006) to ensure the mud flaps stay securely in place under all driving conditions.

Installation

Front Flap Installation: The front mud flaps attach directly to the lip of the wheel well using self-tapping screws. Existing factory fasteners can also be used if available. Installation is straightforward and only requires basic tools. Ensure at least 1/2" of clearance between the tires and the wheel well to accommodate the flap thickness. The front flaps install flush with the wheel well, working seamlessly with accessories such as side steps, power boards, or step bars.

Rear Flap Installation: The rear mud flaps are secured using the included custom-fit rear support brackets and one or two self-tapping screws, providing additional stability and preventing unwanted flapping during rough driving conditions.

What's Included

  • (2) Front Mud Flaps - 12" x 23" Cut Style (GM1223CUTFX4)
  • (2) Rear Mud Flaps - 12" x 23" Full Style (GM1223FX4)

  • Periodically check mounting hardware to ensure it remains secure, especially after off-road use or adverse weather conditions.

Manufacturer Warranty

Gatorback Mud Flaps come with a Limited Lifetime Warranty covering rubber replacement (e.g., tear-offs) for the original owner. This warranty does not cover damage resulting from abuse, misuse, or general wear and tear on brackets, plates, or mounting hardware.

Terms
