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.

Truck Hardware Gatorback Black American Flag Mud Flaps - Set

Enhance the style and protection of your GMC Sierra with the premium Truck Hardware Gatorback Black American Flag Mud Flap Set. Specifically designed for 2014-2018 GMC Sierra 1500, 2019 GMC Sierra 1500 Limited, and 2015-2019 GMC Sierra 2500 HD and 3500 HD (Single Rear Wheel), these mud flaps offer exceptional defense against road debris while elevating the look of your truck. Featuring the iconic American flag on a stainless steel plate, these mud flaps combine ruggedness with a distinct patriotic aesthetic, ensuring your vehicle stays clean and stylish.

Constructed from 1/2" thick heavy-duty virgin rubber, these mud flaps are designed to endure the harshest road conditions while maintaining their flexibility and strength. Virgin rubber is the highest quality rubber available, providing superior resistance against cracking, fading, and warping, making it ideal for withstanding extreme temperatures and exposure to constant road debris. The 12" wide flaps offer full tire coverage, protecting your truck from mud, rocks, salt, and other road hazards that could damage its paint and body.

The Gatorback series is known for its premium quality and rugged construction, ensuring you get the best heavy-duty mud flaps available. Each mud flap in this set features a high-quality stainless steel plate with a American flag design that measures 10 1/4" x 5", adding a stylish, high-contrast accent to your truck's exterior.

Key Features

  • Heavy-Duty Virgin Rubber Construction: Made from 1/2" thick virgin rubber, these mud flaps provide superior durability and resistance to cracking or fading compared to recycled alternatives. The high-quality rubber keeps the flaps in place without flapping, even at highway speeds.
  • American Flag Stainless Steel Plate: The high-quality stainless steel plates feature a bold American flag design, adding a unique, rugged look to your truck.
  • Full Tire Coverage: The front flaps provide 5" of tire coverage, while the rear offer 7.5", ensuring that your truck is fully protected from dirt, mud, gravel, and other debris.
  • Custom-Fit Rear Support Brackets: The set includes custom rear support brackets (GB756802) for added stability, preventing unwanted movement and ensuring a secure fit for the mud flaps in any driving condition.

Installation

Front Flap Installation: The front mud flaps are designed to fasten directly to the lip of the wheel well using stainless steel self-tapping screws, and existing factory fasteners can also be used if available. The installation is simple and requires only basic tools, making it a straightforward task for any truck owner. Ensure at least 1/2" of clearance between the tire and wheel well to accommodate the flap thickness. The front flaps install flush with the wheel well, allowing seamless integration with accessories like step bars or power boards.

Rear Flap Installation: The rear mud flaps are installed using custom-fit rear support brackets and self-tapping screws. These brackets ensure that the mud flaps remain securely mounted, minimizing movement and preventing contact with the tires. This secure installation ensures that your truck is well-protected, even during off-road driving or in tough weather conditions.

What's Included

  • (2) Front Mud Flaps - 12" x 23" Cut Style (GB1223CUTAFB)
  • (2) Rear Mud Flaps - 12" x 23" Full Style (GB1223AFB)
  • Custom Rear Support Brackets (GB756802)
  • Stainless Steel Self-Tapping Mounting Screws

Care & Maintenance

To maintain the performance and appearance of your Gatorback mud flaps:

  • Rubber Flaps: Clean regularly with mild soap and water to remove dirt, grime, and road salt.
  • Stainless Steel Plates: Wipe down with a non-abrasive cleaner to keep the polished finish looking its best.
  • Periodically inspect all mounting hardware to ensure it remains tight, especially after off-road use or exposure to harsh conditions.

Manufacturer Warranty

It does not cover damage caused by misuse, abuse, or normal wear and tear of brackets, plates, or mounting hardware.

Terms

  • Self-Tapping Screws: Screws that create their own hole as they are driven into materials, simplifying the installation process.
  • UV Resistant: The rubber material is treated to resist damage from ultraviolet (UV) light, preventing cracking or fading over time.
