What you get with the set

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.

Instructions were clear, concise and easy to follow. The brackets provide an easy way to hang the mud flaps from existing OEM fender liner mount screw while aligning and securing the rest of the mount screws. Thanks for the assist!

Truck Hardware Gatorback Black Wrap "GMC" Logo Mud Flaps - Set

Add both style and protection to your GMC Sierra with the Truck Hardware Gatorback Black Wrap "GMC" Logo Mud Flap Set. These mud flaps are a perfect fit for 2014-2018 GMC Sierra 1500, 2019 GMC Sierra 1500 Limited, and 2015-2019 GMC Sierra 2500 HD and 3500 HD (Single Rear Wheel). Designed to offer a sleek, custom appearance, these mud flaps feature the classic GMC logo with a striking black background that gives your truck a refined yet rugged look.

Constructed from 1/2" thick heavy-duty virgin rubber, these 12" wide mud flaps deliver outstanding durability and flexibility. Virgin rubber is highly resistant to cracking, fading, and warping, making these mud flaps ideal for enduring harsh environments and protecting your truck from rocks, mud, gravel, and other debris. With the weighted design, you can rest assured that these flaps will remain in place, reducing "sail" even when driving at higher speeds.

The Gatorback series is known for its high quality, and this set is no exception. The officially licensed GMC logo is die-stamped onto stainless steel plates with a hand-applied vinyl overlay, adding a distinctive touch of luxury and personalization to your truck. The plates measure 10 1/4" x 5", providing a prominent display of the iconic GMC brand on both front and rear flaps. Custom-fit rear support brackets are also included, providing extra stability and preventing unwanted movement during use.

Key Features

  • Premium Virgin Rubber Construction: Made from 1/2" thick virgin rubber, these mud flaps are exceptionally durable, resistant to damage, and provide superior protection compared to recycled alternatives.
  • Distinctive GMC Branding: Features officially licensed GMC logos die-stamped onto stainless steel plates with a black background, enhancing the appearance of your truck with a bold, premium touch.
  • Comprehensive Tire Coverage: The front flaps provide 5" of tire coverage, while the rear offer 7.5" of coverage, helping to keep your truck’s exterior protected from dirt, mud, and road debris.
  • Custom Fit with Reinforced Support: Designed specifically for GMC Sierra models, including custom rear support brackets to keep the flaps securely in place, even under tough driving conditions.

Installation

Front Flap Installation: The front mud flaps attach 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 process is simple and requires only basic tools, making it a straightforward task for most truck owners. Ensure that there is at least 1/2" of clearance between the tire and wheel well to accommodate the flap thickness. The mud flaps are designed to sit flush with the wheel well, allowing them to integrate seamlessly with other 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 flaps stay securely mounted and do not flap or shift, even during tough off-road use or adverse weather conditions. Proper installation ensures maximum protection and maintains the stylish look of your truck.

What’s Included

  • (2) Front Mud Flaps - 12" x 23" Cut Style (GB1223CUTG-FULL)
  • (2) Rear Mud Flaps - 12" x 23" Full Style (GB1223G-FULL)

Care & Maintenance

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

  • Rubber Flaps: Clean with mild soap and water regularly to remove dirt and grime.
  • Stainless Steel Plates: Wipe with a non-abrasive cleaner to maintain their polished finish.
  • Periodically check all mounting hardware to ensure it remains tight, especially after off-road driving or exposure to harsh conditions.

Manufacturer Warranty

Gatorback mud flaps are backed by a Limited Lifetime Warranty. This warranty covers the replacement of rubber components (e.g., tear-offs) for the lifetime of the product for the original owner. It does not cover damage caused by misuse, abuse, or normal wear and tear of brackets, plates, or mounting hardware.

Terms to Know

  • Virgin Rubber: Rubber that has not been recycled or processed, providing superior strength, flexibility, and resistance to environmental damage compared to recycled rubber.
  • Self-Tapping Screws: Screws that can tap their own hole as they are driven into materials, making the installation process simpler.
  • Die-Stamped: A process where the logo is imprinted onto the stainless steel plate to provide a sharp, durable finish.
  • UV Resistant: The rubber is treated to resist ultraviolet rays, preventing cracking, fading, or warping over time.
